What are the best lowering springs for CS?
This car has no PASM button .

I consider these options:

-Champion Motorsports
-H&R

Any others?

 

I think H&R gives the best drop and ride performance on the CS.

 

"best" is a matter of opinion. I know folks noted the H&R brings a negative rake on the Cayman... some say they don't have that issue. Personally, I went with Eibachs and they are working great for me. But it's pretty much split 50/50 between these two. Your choices are really down to H&R and Eibachs, these are the two main manufacturers of springs for our cars.
Then you have folks who go with C/O.

 

If you are just looking for lower ride height then Eibach and H&R are a very popular brand used to do so.

If you want to vastly improve your suspension system look into Bilstein PSS9's.

These IMO are the BEST overall suspension upgrade to your CAymann or Boxster.

 

The Champion springs are made by H&R.

 

eibachs are the best choice(i have driven just about all of the options).

 

I just had some eibach springs installed today and they ride great so far. Car looks a lot better now too.

 

Why not go with CR shocks, springs and bars now that they are available? I think that's what I'm going to do.

 

We are currently running a sale on TechArt 987, 997, 997S, Springs. PM for pricing and details!

 

I believe the TechArt springs are made by Eibach.

 

which springs gives the most drop?
