1. What are the spring rates for the MTM/eibach springs.

2. I'm not sure I quite understand why Stasis coilovers use a stiffer spring in the rear when the car has 60% of the weight over the front. Please explain.

3. What is the height adjustibility (fender height) range of Stasis coilovers and ABT coilovers.

Thanks.

I believe stiffer rear springs will help offset natural m4d understeer.

higher spring rates in the rear would promote a neutral driving experience. I would suggest getting 600 front 700 rear and hold off on a swaybar if you had plans to put one on. You will find that it will track quite well with that setup.

That's why I've felt that Avant coilovers on a sedan is actually a great way to get a more neutral feel on other coilover kits such as H&R and KW coilovers.

The weight of the front also contributes to the understeer of the car. Springs are meant to balance the car if setup right and the stasis kit tends to do this very well.

360/270 Eibachs. The advantages of running a progressive similarly weighted spring as stock with a shock with a lot of high compression dampening(Bilsteins) is that you get the best of both worlds in terms of comfort and body roll elimination. By letting your rear bar to the work it was designed to rather than having the rear end be independently stiffened at each wheel, you get the advantage of not having to worry about rear bump steer from road obstacles that aren't present on the street. It is more for a GT set up instead of a track/street set up. This way the shocks and spring design adjust to road conditions vs. the driver having to be more conscious of potholes and road camber changes. Two schools of thought on whether the shocks should do the work or the springs. On a track, of course, advantage goes to the heavier spring. Road course may be different. Also, I dumped my metal rear links and re-installed the plastic ones as I was getting halfshaft contact and a solid axle feel. The plastic links make a big difference in progressive side to side weight transfer in the twisties than the solid links. Still using shims with the rear sway mounting bracket to eliminate potential rear link to half shaft contact. I have a lot of faith in original Audi design engineers and only wish to dial in the product to suit a specific need; being a stealth attack dedicated roadcar.

.... I run H&R Sport Coilovers (470F/470R) with Neuspeed 22 mm rear bar set to stiff. Soft enough for every day street use, but completely neutral on the track with little lean. 1" lower all around. Clears standard bump stops.

22mm/firm with the bracket support kit rules contrary to popular opinion.

Yeah, the kit's a must. Plastic drop links hanging in there fine with many track events (so far).
