Thanks for all the coments guys. It's nice to know there are some other people out there who arn't content with goiong in a straight line. I think I will still start out with 400/325 and see where it gets me. This is my first sentra so I thank all of you for any help you can give. The car ran it's first autocross yesterday, on stock suspension, only a set of 15x7 K1"s with 205/50 Azeina's. I was a full second behind first and second place,( both taken by a fully preped BMW 325 with two good drivers) but the car felt really good. I can't wait to start playing with my AD's!!
