Track Maintance

Untitled

A good rule of thumb, at least with me, is to do oil changes every 4 track days or every 3k miles, whichever comes in first. Another good thing to do that is often overlooked, is to do brake flushes once a year. I visited my buddy Fernando that owns Backyard Auto for my oil change and brake flush.

Untitled

Brake fluid is corrosive. Eventhough the brake lines are a closed system, they do get dirty and can significantly impair brake performance. If you don’t track your car its still a good idea to do yearly brake flushes. Its maintenance that will keep your car running forever and avoid serious complications later.

I use Motul dot 5.1 brake fluid for my M3. Motul dot 5.1 does the job for the track abuse and normal city driving. My experience from the track, is the Motul performs exceptionally well and never had them boil. The brake pedal feels consistently firm and great bite. I can modulate the brake pedal nicely to adjust my braking distance. Only at COTA is when I had brake fade issues but I think that track exceeded the stock brake system. If I had race brake pads and fluids then it wouldn’t be an issue. Motul dot 5.1 is little more expensive than normal dot fluid but its way cheaper then higher temp brake fluids. For me its the perfect match for track abuse and city driving.  The M3 only required one bottle for the stock brake system.

While I was doing waiting, I notice within one week I managed to crack my lip. Comes with the territory when tracking. Unfortunately during TX86 Day, there was a cone in the middle of course and I was unable to avoid it. The lip is still intact but you can see the crack is visible. Battle scars.

Texas 86 Day

86 DAY-01

Soon after coming off from a 12hr shift I headed straight to HPD training academy for TX86 day. I was pretty tired but my tiredness soon went away when I arrived.

86 DAY-08

TX86 day was a event hosted by the people from NST on August 6, hence 86 day. That day celebrates the Toyota AE86 and the newer Scion FRS, and Subaru BRZ. TX86 didn’t allow non 86 owners to participate, but they did offer a pre screening for some slots. Luckily I was one of the few that was allowed to drive at the track.

86 DAY-10

When I arrived there where already a lot of 86 owners that was getting ready for the driving event or the car show. I was contemplating if I should grip or drift, but after seeing the famous Taka Aono do a drift session I made up my mind to go drifting. I brought my spare wheels with brand new Nexin N9000 rubber and slapped them on the rear.

86 DAY-02 86 DAY-10

It was super hot and humid that only got worse in the afternoon. Regardless, people stayed for the show and grip/drift event. From past experiences at that track, its always a good idea to bring drinks for hydration.

86 DAY-03 This Lexus IS300 fitment was spot on. One of the few non 86s that was allowed to drive at the track. 86 DAY-04

It even has an old school Nardi wheel and roll cage for tandem drifts. They didn’t allow tandem drifts at this event and kinda glad becuase Im not at that level.

86 DAY-05 This yellow FRS is rocking Volk TE37RTs with Advan Neovas, and dressed in TRD accessories. Most the cars drifted the course but this car looked well planted focusing on grip. Seems like with this chassis you can tune it for grip or drift, it does both pretty well. 86 DAY-06

86 DAY-07 86 DAY-09

A right hand drive AE86 that was in the show section. Sporting some very deep dish Work wheels and sticky Nitto NT01s.

86 DAY-11 Looked like a work in progress but headed in the right direction. 86 DAY-12

86 DAY-13 A FRS/BRZ rocking the Varis body kit in the show section. The aero looks soo aggressive that it could do a time attack.

86 DAY-14

The Volk and Brembro combo looking nice.

86 DAY-15 86 DAY-17

Slammed BRZ in the show section. I remember when I was about that life.

86 DAY-29 Simon Chan’s TSX. 86 DAY-31

86 DAY-32 Neon interior light for JDM. 86 DAY-16

Simon setting up the drift course for the RC cars.

86 DAY-30 RC drift action. 86 DAY-34

86 DAY-28 86 DAY-19

86 DAY-20 The NST booth that hosted the event. The black AE86 with the NST logo is actually Taka Aono old drift car in the OG days. 86 DAY-21

86 DAY-22 86 DAY-26

The AE86 with the red wheel is Taka Aono current drift car that competes in the Formula Drift series. It produces 700hp!

86 DAY-23 The 700hp beating heart. 86 DAY-24

86 DAY-25 Taka Aono and Yoshie Shuyama offer drift school in California. I feel pretty thankful that they came from California to Houston to celebrate 86 day. The VIP drivers got an opportunity to get lessons, which I felt like I missed out on. I didn’t get a chance talk to them personally but I could tell they made their passion into a career and thats something I want to work towards too. I like nursing but my passion has been racing.

Simon Chan was able to get a dope picture of me sliding and kicking dirt up.

After 24hrs of no sleep, a day of just drifting and catching up with friends the tiredness caught to me again. Next thing I knew, it was 4pm and was hotter than an oven.I had a great time but I was feeling the heat. So I switch to my Volks, packed my gear, and headed home. Till next year, I hope I can join TX86 day again!

I think its only appropriate to end this coverage with my homie Thaison and his newly acquired AE86 Black Edition. Thaison just slapped on Work Equips and really gives that Hawaiian/Cali look to it. Dope photo taken by the famous Simon Chan.

SCCA Track night: MSR Cresson

Another fun day at the track. This was my first time racing at this track and was pretty far drive from Houston (4hrs). I racked up about 800 miles part of which was because I stayed overnight in Austin. Even though I track once a month I joined the novice class becuase it is my first time here. I was thinking the track would be pretty empty since its was 102 degrees outside. Surprisingly I counted 11 cars in the novice class, and was actually less drivers in the intermediate and expert class.

MSR cresson-02 When I got there, the covered garage was filled! Grudgingly I unloaded all my tools and tires in the Texas sun. I did leave my tires and tools in the shade, at least there was room for that. Untitled The silver Lexus IS300 is actually pretty fast in the straights, I later found out it was LS swapped! The track day included 3 sessions, each being around 20 mins. On the first session, I was behind the IS300 when it started smoking bad with the smell of burning metal. Soon afterwards it smoked very badly and pulled over to the side of the track. Then session was black flagged and required everyone enter the pits. We waited roughly 10 mins for the track workers to clean up the spill and I found out the IS300 blew a power steering hose. Thankfully we were able to get back on the track to complete our first session. MSR cresson-03

This Jaguar was just cruising on the track top down. Not that Im saying its slow at all but you could tell the guy was just out there to have a good time. Its about the experience.

MSR cresson-04 Mini Cooper on Bridgestone RE-71R. I’ve seen a lot of people run RE71Rs on the track and autocross. They say its better then the RS3. I need to try those out. MSR cresson-13

The 2nd session went through without problems and I got in a friendly competition with the Mustang Shelby GT350R. These days you always see jokes and memes how bad mustangs handle. Even on YouTube, just a simple search and you can find videos of drift and burnout fails of mustangs. I got to hand it to Ford making a track oriented car. The GT350R could never pull away from me but I couldn’t pass it either. We were evenly matched and pushing each other to the limit. This was the hardest I pushed myself and the M3. The last couple laps my tires got too hot and grip fell off. I had to back off and let my tires cool but thankfully the checkered flag was waving. After the session we shook hands on a great race. Unfortunately, which seems to happen often, my memory card was full by my 2nd session and the epic battle wasn’t recorded.

MSR cresson-20 This was the GT350R I had a friendly battle with. Definitely sounds like a roaring V8, and the owner recently bought it! Still has the paper plates! For those of you that don’t know the Mustang 350R here is a little info:

After such an adrenaline filled session, on my last and 3rd session I just played it chill and didn’t go to hard on the M3. I was shifting early and using 3rd gear on 2nd gear corners. That session went on without incident and was great. The 350R did catch up to me but I let him pass, I know he probably wanted another duel but sometimes if you go over the limit that when bad things happen. After the 3rd session, the sun was setting and was just that perfect lighting to take a picture.Happiness eludes those who seek it. True happiness is the by product of the journey. #abrhouston #bmw #m3 #hankooktires #te37rt #tracknight #scca #natsukashigarage MSR cresson-12

Lady driven Porsche boxer was in our run group.

MSR cresson-18 MSR cresson-05

Lots of V8 today.

MSR cresson-08 Mustang Cobra is supercharged with pullies and tune. The car is mainly used for drag racing but the owner still had a good time at the track. MSR cresson-07

This truck was a complete custom build, tube chassis, modified frame and with a supercharged V8. Unfortunately it only did one session becuase trucks are not allowed on the circuit. Look good though, like the rat rod look.

MSR cresson-06 You get a good mix of cars in the run groups which makes things more interesting. MSR cresson-09

Four bangers were also out too.

MSR cresson-14 MSR cresson-15

I thought this S2000 was on Hankook TD but its was rolling on Ferderal tires… I wonder how they feel at the track.

MSR cresson-16 Big Wang. MSR cresson-17

Harrys Lap timer was working seemlessly and I managed to clock 01:31.53 seconds, which I have no idea if thats fast or not. But it felt good just being out there.

MSR cresson-19 Heat cycled Hankooks did a really great job. They only over heated once because I pushed too hard on my 2nd session and grip fell off. It handled the abuse in the 102 degree heat.

Untitled

MSR Cresson consists of high speed long sweepers, late apexes with a few tight twisties (aka the rattle snake). The track isn’t terribly fast, but I managed to hit 100mph on the straights. With shorter straights and longer sweepers, the track isn’t harsh on the brakes compared to COTA or Harris Hill. You can with the amount of brake dust after my last sesson. What I really did like was how smooth the track was. The track is well kept and very close to gas stations, some even offering racing fuel. I’ll be back again. MSR cresson-23

SCCA track night Harris Hill

Ever since my first track day at COTA, I’ve been going to track events once a month. But this will be my first time at an SCCA track night event, and I wish I knew about these events sooner. Its like HPDE except its a lot cheaper, with fewer sessions and you learn at your own pace without an instructor.

Track day 🏁 #m3 #bmw #herrishillsraceway #te37rt #hankook #natsukashigarage Harris Hill is about a 30 min drive from Austin, with elevation changes and long sweepers. My friend Jason, with his track oriented Miata was able to join in on the action. It was our first time at this track, so we joined the novice group. Thankfully there were only 7 cars in the novice class. Probably the Texas summer heat might be to blame for low number of cars but I wasn’t complaining. I hate to race in a crowed track. What a great way to end the day #miata #m3 #herrishillsraceway  #natsukashigarage

SCCA track night is $150 which includes three 20 min sessions. The novice class also gets paced laps before the beginning of the first session, and drivers meeting between sessions. Luckily SCCA does offer discounts and I was able to get $25 off. The people are pretty chill and its about having fun in your car. You get to experience what a track day in a chill atmosphere. You don’t get an instructor, but in the paced laps, the lead car shows you the preferred line. I still like HPDE becuase they offer instructors and more track sessions (5),  but the price sometimes is too much for some people. SCCA track night just makes it more affordable to the general public.

Untitled

Unfortunately my lap timer was acting up and I wasn’t able to time myself but I still had a blast. My first impression was this track is slow but its decently fast. I was able to hit 110 mph on the straights with no brake fade! The stock M3 brakes are more than capable for track use. The only time I had brake fade was at COTA with stock brakes, Im pretty sure if I get track pads and higher boiling point brake fluid then it wouldn’t be an issue.  I can really feel the g forces in the long fast sweeper. Harris hill is mainly a 2nd to 4 gear track. The only thing I didn’t enjoy so much was how bumpy the track was. My suspension isn’t super stiff, but if you are not careful the bumps could upset your car and lose control. I didn’t run into any issues, but it was a rough ride that my helmet would occasionally hit the roof. During the drivers meeting, the SCCA track host gave us pointers around the track which did help avoid some of the bumps. By my third session, I was pushing the car harder and I really enjoyed the capabilities of the M3. I will be back again.

Dreaded Bleeder Screw

Since I do a track event once a month, and its the middle of  Texas the summer. I knew I would be racing in 100 degree plus heat. I was nervous about about overheating during my next track day at Harris Hill. With my M3 hitting 60k miles, and just a week before track day, I took my car to ABR Houston for a coolant flush. Unfortunately the plastic bleeder screw is fragile and can break easily, which is what happened on my way home after the leaving the shop. My low coolant light came on midway driving home. I immidiately added distilled water from a nearby grocery store and the low coolant light never came back on. But when I got home and opened the hood…

Untitled

Looks like the expansion tank spilled coolant everywhere! I was totally bummed and worried that I wont be able to make it for my upcoming track day. I let the car cool down and called the guys at ABR Houston. The service advisor informed me that some coolant did spill out during the radiator flush but when I first popped the hood to add distilled water the amount of spilled coolant was minimal. I didn’t really worry but I started thinking…. It only got worse when I arrived home after adding distilled water. I didn’t overfill the expansion tank since there is a bevel that tells the max level. You could still see the fresh coolant around the bleeder screw.

Untitled

After letting the car cool and being all bummed about what happened I started to wipe the dried coolant from the engine bay. As I was wiping the expansion tank the top of the bleeder screw came off!!!

Untitled

Worse case scenario, I have a partial screw that is stuck in the expansion tank. I did some research and found out that the plastic bleeder screw is known to break easily. I called up ABR Houston and spoke to Alex about the situation. Alex, the shop owner, was nice enough to drive from his shop to my apartment in downtown, and this was during rush hour! Alex was able to remove the broken bleeder screw with a left handed drill bit. The left handed drill bit catches on screw and which enables the screw to turn counter clockwise. The broken bleeder screw was replaced with an aluminum bleeder screw that wont break. So I was able to make it to my track day and race without any issues. The guys at ABR Houston know how to work on BMWs and really take pride their work. ABR Houston also did my engine bearing replacement the beginning of this year. VAC coated bearing with ARP rod bolts and no problems so far.

Learning Levels of Grip

Recently my last track day, the forecast called for thunderstorms. This was a good thing because I wanted to feel how summer tires fair in the wet when you are really pushing the limit. I was on worn out Nitto NT05, and on the dry they are great tires. This is actually my 2nd set and the cheapest 200 treadwear tire for my size. I would like to thank Alex from http://www.street-form.com/blog with the dope pics!

Untitled

Unfortunately I didn’t have a tent for my tools and spare wheels so those got soaked. At least I didn’t need to use them. Out on the track its was a challenging to drive clean and being careful not to go off course.

Untitled

What I learned racing in the wet:

1. Don’t go all out in your first run….. I noticed people at the track tend to go all out when its the beginning of the session. For me, thats not how I do it. How can you run if you can’t crawl, right? If you go balls to walls on the first run, you have a higher chance of spinning out or worse crashing becuase you are not familiar with the course or track surface. I like to go smooth and steady first and learn the course before I really push it. Slowly increasing speed and braking later with each run. You got all day, whats the rush.

Untitled

2. Nitto NT05 work well in the rain even in when its worn out! I thought I was going to be all over the place but for the most part my car felt stable and grip was there. There is a long sweeper on the course and I was thinking the NT05 wont be able to turn in the wet but it gripped! I was even adding gas to the sweeper to see if it would understeer but I got oversteer, which isn’t a bad thing. I want oversteer instead of understeer becuase you can turn the car in better and can control it better (if you get it right). When the tires did loose grip, it was still predictable and progressive. The NT05 gave me confidence to push harder. I never had a sense that I was all over the place.

My tires my before track day

Untitled
My tires after tack day. They wore out pretty fast even in the rain, but I was running nonstop with a couple of 15 mins rest sessions.

3. You can’t go as fast compared to the dry… Duh. I know it sounds dumb and common sense but to actually experience this is something that you really understand. The grip is very low in the wet and its something you have to account for. Your braking comes in sooner, than in the dry, and the pedal modulation is more sensitive to your input. I was learning to control the tires from spinning too much or sliding out of control. Hydroplaning is a big thing to watch out for and trust me when it was pouring, like cats and dogs, it felt like those tightrope walkers. One wrong move and its the end. You have to find that very small window of grip because too much or too little gas, brakes or steering can send you out of control. The faster you go, that small window of grip becomes even smaller. Yes is did go off course a couple of times but that is becuase of driver error and not the car. Here is video of me learning the course then losing it but luckily managed to stay on course.

4. A wider tract makes a difference! So last week before this event I went on to a autocross and I took off my spacers, because I was worried of rubbing. Well since it was raining I didn’t want to get wet removing my spacers, so I kept it on. I can tell the 15mm spacer made a significant difference. The 15mm spacer in the rear made the car feel more stable and planted than without the spacer. I was feeling this in the rain, what more when its dry!

Untitled

Managed to get 0.8g in the wet! I honestly don’t know how accurate that is but I was using my iPhone for my car telemetry.

5. Its okay if your car gets dirty. Maybe I should pull up to Wekfest like this….
