I am going to try some progressive rear springs on a metric street stock has any one else tried this ? I have used them on a car built for a pure stock type car they where moog cargo coils they worked well . I am going to buy racing springs for this street stock.

Tried them, Hated them! I had excessive wheel hop off the corner and they just felt "weird". Maybe my shock combo wasn't right with the springs but I didn't feel like throwing money at them to get them to work right, if that's possible.

Won a lot of races with them this season. To do the same thing the year before I had to changed springs after ever race...

I think the trick is to run the lightest sold (150 to 350) and run a pretty stiff front spring package. If I told you how stiff our fronts were -- well you wouldn't believe I won't. However, I will be trying to lighten the fronts this season just to see what I might be leaving on the track by being too stiff. It was just nice to have a set up that ran well wet or dry...and never once changed a single spring.

We run a 6 compression 8 rebound LF, 5 – 7 RF, 5 – 5 LF & 3 – 5 RR for a dry track. We adjusted the LR last season with a 4 – 5 early in the night, but this year I’ll be changing the RR from a 4 – 5 to the 3 -5, getting back on track with the conventional wisdom that you lighten your shock numbers as the track gets dryer. I use QA1 shocks and re-valve them myself.
