Grip not too bad really - quite progressive and manageable coming on the power overall but defintiely struggles with grip more compared to when it was running at 1.5 bar.

Having the Syvecs traction control is handy at dealing with it most of the time so far, especially whilst I'm getting used to the power!

Looks good man. I'll bet it brings many a smile to your face every time you drive it :)

Does anybody know what a 600hp Supra would trap in the standing quarter? (rough figure, i know the launch affects it etc, but let's say an average launch for the purpose of this question)
