Hi,
I have a similair setup and also not happy with my car handling.
- Full m3 stuff, Drexler LSD, suspension/engine "mounts" replaced with medium hard rubber versions
- M-sport sway in the front
- M3 sway in the back
My issue: I lose traction halfway the corner on my outer rear wheel.
This is caused due to the to stiff rear m3 sway bar.
My plan:
- Chamber plates in the front (More negative chamber)
- Linear spring around and in the rear also stiffer springs
- Replace the rear sway with a normal m- sport sway
With replacing the rear sway back to original I hope to achieve 2 things:
- Bring the car back in balance
- Allow the rear wheels to move more independent
With the more heavy rear springs I hope to keep longer traction on both wheels in the corner avoiding sudden oversteer.
I have learned quite a bit myself form the following two sources:
http://www.racingonthecheap.com/reco...andling-guide/ (Very clear per situation)
and this book:

My adjustments should be finished around the 15th of October and I hope to return to a race track early november before the winter kicks in over here.
Hope this is useful for you..
