@JOVA1982 , @Killrob, @TrackpadUser, you guys are awesome. I will have to try these based on your advise
- Reduce turbo little bit to see if that can compensate lag (still trying to achieve the acceleration of 4.5), reduce ar ratio
- increase height,
- @Obfuscious - The rear grip is a slighly curved line, the break force is just above that line
The other question is , the steering graph tends to show over-steer for most of the speeds no matter what.
