I manage to beat my PR by 0.8 seconds! This was during the Drivers Edge HPDE in March https://natsukashigarage.com/2017/03/16/drivers-edge-hpde-at-msrh/. Im really happy I was able to attain that goal since the time is comparable to other M3s with coil overs and sticker tires. I did noticed as my gas level goes down my lap times gets faster too. Im guessing 14 gallon tank weighs a lot more than when you have 5 gallons of fuel. Pretty happy with that time and I hope I can be a better a driver!
Here is the full video but no telemetry though. I have a hard time linking up the go pro with Harry’s Lap to overlay the telemetry. There are some slights and faster cars that pass me so its not totally boring.
