Front spring question

[FredG]

I can tell you from experience that you need a soft spring rate in the front because these cars are so light. I installed camber plates and 350Lb Eibachs and they are too stiff. I will be swapping them out for 300 or 275 lb springs. The racing suspension shop that did the alignment and weight balancing told me to go to progressive rate springs.

My 92 buildhad a very bad ride , the rear spring spring jack bolts would bottom out in the top spring pocket.these were original springs hat were weak replaced all rear control bushings with energy suspencion bushings and 325 pound rear Iebach springs ride is greatly improved.do need to go with the pro shocks I think haven't done anything to front set up but ddidtake off sway bar it is just to big for these low weightcars in my opinion

C5GTO. You mention that a change to coil overs can happen with a lower control arm change. Is that all? Is the upper shock tower strong enough to handle the forces of a coil over setup?

Yes, that's the only change I had to make. The upper part of the spring still uses the same spring mount/seat as a regular MII spring. It's a conical spring so the spring width tapers from larger at the top to smaller at the bottom. I've seen several sources for this type of "coil over" for MII suspensions. I suggest you shop around to find which would work best for your situation.
