Thats funny heal and toe. HAHAHA!!!! Oh Please unless your some race car dynamo at Sebring or something there is not much need for it. Ive autocrossed several times at 5 different locations and only once have I ever shifted into third. (huge airport track in Texas) And only on a VERY rare occasion have I needed to downshift into 1st gear. Im talkin really tight 90 degree corner too at Sunriders.
If you find yourself shifting a lot at an autocross event. Your probably doin something wrong.
