I bought an 04 cobra back in july. The car has aftermarket springs in it already. The car has a really good stance,but that's about it. I took the car to the track about 3 wks after I bought it and my 60' times were horrid and the car spun violently. I ran with my 18'' saleens with et street and my pro stars with 555rs with pretty close to the same 60' times. I know the 18s have no side wall or give and the 555rs are pretty much useless from past experience. I recently bought a set of coil overs for the front and the car has upr upper and lowers. I plan to switch those out with my baseline upper and lowers. I'm also going 90/10s or strange 10 ways on the front. Just curious as to what springs you guys are having luck with?
