New Bearings and UUC Underdrive Pulleys Installed

May 14, 2009

Lana didn’t get to finish her afternoon runs at the 1st BMW event because the left front wheel bearing started to make noise. A few days after the event I brought the car to Nick at Ace Performance Systems to have both front wheel bearings replaced. Nick is a BMW Technical Training specialist, is BMW Master Level 1 certified and an all-around great guy.

I had been planning on installing them myself, but Nick has all of the right tools and is a much better mechanic than I will ever be. I haven’t had the car on a dyno since last year and can’t provide any accurate “before and after” results, but UUC Motorwerks claims a 4-11 hp increase. The M3 can use every bit in it’s battle with the Evo and STi in the SCCA STU Class.
