Orb, what's the spring rates of the KW's? Since you said you would change them out if you went with KW's.

In would get the Clubsport and order KW 70 N/mm x 170 mm (400 lb/in x 8”) springs. I'm actually running a 200 mm long front spring with 3 N/mm x 80 mm helper spring (compresses to 12 mm). I went with this setup since I will be working within the linear range of the spring even at full travel. The 170 mm long spring barley cuts it for full travel.

The 400 lb/in front and 800 lb/in rear has proven to be a good setup for e90/e92 with the stock M3 roll bars.
