Has anyone installed any of these products on PASM C2S; EIBACH Springs 7217.140 or BILSTEIN B16 Damptronic Suspension System? All I want is to lessened the wheel gap a little less, currently at 2 fingers gap height, and I would like a 1 finger gap height.

I have an '08 C2S with PASM Used the TechArt springs lowered it nicely...not too far at all perfect with the PASM

Eibach makes the springs for Techart. Both will get you to the ride height you want, inexpensively.

If you've money to burn and will spend quality time at the track, there are several systems in the Bilstein price range to choose from.

Thx col328 and kdurg! Do you know what is the cost of the Techart springs as the Eibach's are approximately $350.00. Do the Techart springs make the car ride firmer like in the PASM FIRM mode or does it feel like PASM NORMAL? What is the wheel gap distance when installed since the Eibach's spec is 1" lowered which would mean no gap since the C2S is already 10mm lower than the standard C2?

Both the Eibach and Techart springs are Progressively loaded. So, the ride while not under load will be comparable to stock.

I've done plenty of research on what if any differences exist between the two springs. Aside from price--Techart being more expensive, no one has been able to elaborate on differences in spring rates or manufacturing process. IMO, although no one from either company will admit this, I think they're the same spring with different branding.

Another alternative is H&R springs. There is a current thread going from Carrera Mike describing the install and ride height measurements on his '06S. H&Rs will drop the car more than either the Eibachs or Techarts-----check it out.

Good Luck.
