Had a set of these on my E36 Euro M3. They were really good and were well thought of in the BMW community. Tightened up the handling, roll and were compliant over bumps.

These are £800 or $1200 but include top mounts. Top mounts alone on a 996 turbo are $250 each side so they may be a bargain.

Anyone tried them? I know they don't have a reputation like Bilstein etc.

 

check out the link in my sig. Ive been trying to consolidate suspension threads and reviews.

 

I bought some lightly used set a couple of years ago as a stop gap because my stock stuff was feeling pretty blown out. Didn't intend on keeping them long when I put them on, but I have liked them well enough that they are still there. It's not my main track car but stills sees some time. Plenty good I my opinion for mostly street.

 

I Have them....and like em!. Fully height adjustable, set on fairly soft for the street, much nicer than stock. I have not tracked yet, but I did set to firm for a test, and they were pretty stiff, which should be good for the track. I am glad I got em.
