The fix for this issue is to go to the M3 bush system great for a road car on road tyres.
But if you are doing track days and semi slicks go for the soild bush set up from Turner Motor Sport, at the same time go with the M3 arms or for track cars use the Megan arms.
Or if you can find one go the complete M3 rear with LSD and go from there, the sky is the limit with these cars
We have done many differant setups if i can help just give Peter a ring at Advan Performance
