Leaf + coil springs?
Hey guys. I just got a set of used pfadt v1 coilovers.
Looking online at the spring rates, I'm seeing this:
C5 Z06: 526# Front, 714# Rear
Pfadt Coil-overs: 425# Front, 575# Rear
My c5 is non-Z with hotchkis sway bars and I would like more roll stiffness at the track. Personal preference.
Is the lower spring rates mean it'll be softer or is there a weird moment arm and wheel rate thing going on?
If it'll be softer than stock leaves, can I add a 100lb spring on the shocks and have it help the leaves?

The point of Coilovers is to replace the Leaf spring setup. You don't run both. I would suggest running the coil over with the springs they have on them and then stiffening from there. You can get a pretty much infinite number of spring rates from a lot of places. Also Id check to make sure those Pfadts aren't blown as from reading a lot of people had issues with those coilovers blowing.
