Hi all,
I just picked up this 2009 e92 335i with the M Sport. The front struts were replaced about 10K miles ago with B4s. I don't think the rear shocks have been replaced (113K on the car). I am thinking about taking the car to the track, maybe 2 or 3 times a year (High Planes raceway outside of Denver). I am happy with the ride height but I would like to upgrade the handling a little. I was thinking maybe the Bilstein B6 shocks and struts or B8s. Any thoughts here? Seems like maybe the B8s are for lowered cars or am I getting bad info? What do you guys recommend? Given 97% of the time, the car will be spiritedly daily driven and not at the track, is this a good plan? On a scale of 1 to 5 where 1 is the slushy stock suspension and 5 is race car, I'd like to be somewhere around a 2.5-3 if that makes sense.

Second, I see that Turner has M3 control arm kits by TRW for the front and rear that upgrade the joints for a tighter feel, better feedback. Is this worth the price ~340 for the front kit and ~ 520 for the rear kit? Or should I be looking at something else? I figure with 113K, the joints are probably toward the end of their service life.

Am I going to be happy with this setup or should I just go full coilover kit now? Any other options for the control arms?

I do plan to replace the strut and shock mounting hardware when I do shocks and struts too.

Any feedback is appreciated.
