No questions just a bit of feedback after getting help from this forum.
E90 330i with 9,000km
Finally fit new Koni Sport springs (lowered it 30mm) and Koni adjustable dampers. Dampers (front) set at 40% from full soft position, rears are non-adjustable.
I had already replaced the OE 17" 162 wheels with 18" jobbies and the OE RFT's were jettisoned in favour of S-03 Pole positions.
A massive transformation from a fairly rolly polly handling standard car.
Body control is excellent, with a huge reduction in roll.
Ride comfort with the this package is better than the standard car with RFTs.
To confirm I took my mate for a spin (he has MB SLK350) and he was mightily impressed with the handling.
Now for the brakes.................
