    Looking to buy and/or trade a OEM 3.62 Differential for a 3.91 or 4.10; OEM starting leaking so now is the time to swap.
  3. Where to get 4.10s installed in SW Ontario?

    ///M3 Forum
    Purchasing 4.10s :excited:, and am looking for a shop to install them. I've heard good things about both Bimmersport and RMP Motors in Toronto. Has anyone had gearsets installed there (or somewhere else) and/or can comment? Thanks
  4. 4.10 gears

    ///M3 Forum
    Can anyone recommend a reputable NY area shop that does work on differentials? I would buy the ring and pinion set along with the installation kit and take it to a good shop to have them rebuild my differential. If anyone in the NY area has changed their gearing please help me out. Thank you...
