think i figured out why i have traction issues-
 

as some of you may know, my suspension works differently than most of you
cut a 1.8 60' on street tires

well i had shorter rear springs, (out of a 3rd gen rear) and im pretty sure it had a different spring rate as well
thats when i hooked hard 8) 8)

now, i put my stockers back in a month or 2 ago and havent really ran it much at the track, and when i did, the best i cut was a 1.99 on DR's! :huh: :scratch:

so im switching back to those other ones because thats the only thing i could thing of. ill have to get pics of them to clarify it furthermore

If you can get the spring diameter, number of active coils, and coil thickness you can calculate the rate.

sounds like a good idea
