New Bearings and UUC Underdrive Pulleys Installed

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.
