  • Deep six run-flats for non-run-flats
  • Sub M3 for wimped stock rear subframe bushings
  • Install limited slip differential
  • M3 sways - only if LSD installed

Just installing the M3 subframe bushings will fix this. Huge improvement. But this isn't a job for the timid.

Hi.
I recently installed this Dinan kit on my stock M Sport suspension. I have a 2011 e92. I noticed a big difference right away:

http://dinancars.com/product/d110-0008-rear-upper-shock-mount-kit-10mm-for-bmw-325i-328i-330i-335i-335is-2/?series=3-Series&mid=1122/

Also plan on doing the Whiteline subframe bushings, hopefully this week with this kit:

Look into these for low cost mods.

I'm switching to non run flats this spring.

you are better off asking that in the UK subforum... insurance laws vary greatly from country to country.
