i just started the autocross in my area. i didnt do to bad i took 4th place in my class out of 13. but seems to like to wag its tail around in some of the more tight corners im thinking about getting a full Tien suspension kit to help with the body role and just stiffen the car over all what do you guys think is Tien the way to go or is there something better

Yes, I would say that for right now the Tein Complete Coilover system is the way to go. I say that Tein's are the best route for what's out there now. Unless others have a different opinion?
