I will try to find information on front m3 control arms for alignment shop. In several threads, some people mentioned that rear M3 arms are the same as regular 3 series and that other than providing better bushings, no other gains are to be had. Is there a difference between upper and lower rear control arms (m3 vs regular)? Just to clarify further, are uppers same as regular 3? Are lowers same as regular 3? |

Rear M3 arms are _identical_ to stock arms with the exception of the way they're made. Same length, same bushings, same spherical bearing. They have _zero_ effect on handling, don't waste your money. The M3 lower camber arm (spring arm) retrofits cleanly with the exception that the shocks will need to be changed to accommodate the different lower mount design. Helps a bit with handling but afaic not worth the effort without replacing the inboard bushings with welded-in spherical bearings.

Rear subframe bushings recommended and i need and you may need to rear camber arms. With my lowering and monster tires i need to adjust the camber slightly more than oem allows. Wait till alignment to find out if you need.

bushings are def on the list. I think I might do M3 set instead of powerflex. However, I will cross that bridge when i get to it.

I used stiffer than m3 and no regrets. The stiffness of m3 is v65. There's v75, v95, and solid. I used AKG v95 black so there was some but minimal give. Works great.

I should also mention I've used the M3 upper arms for about 20K miles and then switched to BimmerWorld adjustable arms with Aurora Performance Race ballends and the difference is obvious and an extreme improvement. The M3 arms just weren't ever right, definitely didn't help handling at all.

Do you have a study with results for a 335 with OEM arms vs M3 arms in the rear. I just installed rear m3 control arms 2 months ago and the bushings in the m3 arms are not the same vs the bushings in the OEM arms. |

[edit] The main point here is that the M3 arms offer absolutely no improvement in handling at all. If you've driven a car that can handle the difference is readily apparent. [/edit]

Do you need to do anything besides the 4 sub frame bushings? Any improvement from doing diff bushings or anything else while I am in there? My car is DD so I want to keep it very streetable. I am looking at whiteline bushings. I have had them on other cars in the past and they were very good.
