For a dedicated track car, is there a real difference between Weltmiester rear springs and Eibach? I am thinking 140 lb springs on Bilstein sport shocks.

Sway bars to be decided later, or should that determination be made in conjunction with the springs/shocks?

If I had my choice, I would choose Eibach, but I have no scientific evidence to support that decision.

weltmeister 140's are what i drive on the street.... i think you would want stiffer springs for a dedicated track car...just mah .02

Eibach's all the way. Weltmeister's, with the exception of the 140# springs are progressive. I have found that to cause handling to be different, depending on the corner. Lower speed aharp turns caused me to understeer like a snow plow. I have found "suspension heaven" with 22mm torsion bars, 22mm Tarett sway bar, 200# rear springs. Next up is a set of Muellers Bearings and a set of those fancy strut mounts

"dedicated" in what class ? is this a PCA Stock Class Club Racer, some kind of Improved Touring class, or an all-out big-horsepower/monster slick class ?

my preference would also be for Eibach but i don't have any hands-on A/B data to support it ...

there's also a few valvings of Bilsteins so just knowing the name doesn't help specify much, although i agree with your choice :-)

yes - the suspension is a system - springs (torsion bars), antiroll bars, dampers (shocks) and all the parts must play together (for best results).

as always - Step Zero is to read the rulebook for your intended class and make sure you know what modifications are legal before beginning...
