The minimum upgrade I would recommend for every 135i is Koni Sports or FSDs, E92 M3 front swaybar, the $65 HD front bushings, and for track, camber plates. I didn't mention the linear rear springs because I don't have any experience with them, so I don't have an opinion about them.

Thanks for the advice. So I guess this would be the list of items I am contemplating.
- Koni Yellow Shocks x4 (How often do people play with the rear external adjustables? Want to know if it's worth it)
- 09 Stock Springs vs 2010+ Linear Springs vs PS Springs... or other Spring recommendation with minimal drop but won't expose the subframe bushing weakenss too badly?
- Ground Control Hybrid Camber Plates vs Voshlag Camber Plates? I know the Dinan doesn't give enough camber without M3 wishbone, which would probably put me into a hole of getting the M3 tension rods and M3 control arms also..? Probably also stiffen stuff up too much in the front to expose some bushing weakness up front.
- E92 M3 front sway
- HD front bushing
