If any of you are still out there, I need some advice.
I have a 128i with M-Sport Suspension 90k miles.
For street fun and autocross.
I would like to upgrade the stock dampers (and springs if possible?)
The dampers are due to be replaced anyhow I'm sure.
Springs, I'm not so sure about?
If I keep the stock M-Sport springs, which Bilsteins would match the springs?
As much as I would like to go with the B12 Pro Kit I can't afford to lower the front any more than it is now. (Fronts were rubbing where the fender/bumper connect going over speed bumps and in to driveways. It has self clearanced) However, if the front springs are sagging and the B12 springs would actually keep the front where it is, I'd be a happy man.

I should add that when auto crossing, the front suspension bottoms out in tight corners. I figure new dampers would help, springs and dampers would be much better.
I'm running:
Front
17x8 40mm offset 225/45
Rear
17x9 45mm offset 245\40
