Glad I could help. I am pretty sure I was using sport tires initially, I use whatever Bob has to use. Definitely requires good throttle control, which is hard with my DS3.
I would get Limited Slip Diff and try playing with that. I always meant to, but never did. Maybe that will be my project for the long weekend. I am thinking of raising all three settings, but probably acceleration the most.
I was also thinking about adding a little more rear camber, to try to keep it from kicking out exiting the corner under acceleration.
Did you do the 7/7 extension settings?
