TW/FT: SD Bilstein suspension

This setup is very stiff. Not suitable for daily commutes at all. This is the ONLY reason I want to go for a different, softer setup.

Stewart Development revalved Bilsteins
550 front springs
400 rear springs
Allstar adjustable perches
Fat Cat bump stops all around
ISC top hats all around

Setup has around 2,500 miles on it. Really would rather trade for a softer setup instead of selling but if I'd have to put a price tag - $1,100 + shipping would do.

would you consider a trade for barely used megan EZ streets? less than 500 miles on them.

I've paid right around $1,400 for this setup so I guess around $500 is reasonable without top hats. What generation FM springs?

$500 on top is a bit much for me

Have you owned different suspension prior? I had the same spring rates and it was quite comfy. Comfy enough that I moved up to a stiffer spring rate, 672/448. Are they shortened? Bilsteins IIRC originally have 4" or so of stroke in the rear, maybe it is hitting the bumpstops too often? I almost want to get your opinion of ride comfort in my car.

Here are PDF's of the shock dyno.

These look to have just a bit more rebound than my SD Billies by about 50# at 2 inch second on the fronts.

Awesome track set up, I have 2 sets on 2 different cars-550#F/350#R. Very firm on public roads, good road feel but bumps are pronounced. I'd say that they are overkill and a bit harsh for a purely street driven car. For a street driven car I'd suggest 300#-450# front rates.
