911 SC: Suspension tuning for Street/Track car

Hi guys!

Last weekend I was giving it my best at the Zolder track in Belgium. During that time I noticed my a** was being kicked thoroughly by all kinds of hardware. Especially those little Lotus thingies.

On the straights I had more than sufficient power to keep up.

The problem was mostly situated in the corners, where my car seemed to understeer quite a bit (also in the fast corners). This could be caused by either my incompetence as a driver or as an engineer. Or a painful combination of both.

Now for the facts:

Setup (911 SC Coupe):

- 21mm front torsion bars
- 26mm rear Turbo torsion bars
- Bilstein B6 shocks
- Carrera sway bars. 22mm front, 21mm rear
- Corner balanced: with driver 10 kg difference rear and 2 kg difference front

Since the car is already pretty harsh on the road (Belgium = poor road quality) and I do not want to make that much worse. I want to be able to use it for a nice sunny sunday drive. But I've heard that overdamping could compromise ride quality and swapping to bigger bars that match the bilstein shocks better could even improve things. Is this true ?

Possible solutions:

- install 20mm torsion bars in the front
- install 27 or 28 mm torsion bars in the rear
- buy a Lotus


What do you guys think ?

Thanks!
