anyone autocrossed a 2011 gt auto if yes did you lock the tranny in a gear if yes which one.
also how did it do overall??
I have autocrossed mine a couple times now. I first tried just keeping it in second, but found on courses with a longer straight I hit the rev limiter with stock 3.15 gears. I ended up just leaving it in "D" and got much lower and more consistent times.
