WTB 128i M Performance brake kit 34110444772

[Thunderguts]

I waited too long to get the 34110444772 front and rear kit and now it's NLA. If anyone knows where one might be stashed away, please let me know.

I don't think I'd be interested in a used kit, but maaaaybe.

There are many used 135i brake sets on eBay for roughly $900 (set of 4 calipers only). That's a pretty fair price for what you get. ECS tuning also continues to sell the front performance calipers. Oddly, they are cheaper than the std 135 calipers even though the only difference is paint.

Build your own set. 135i calipers in the front (or the performance calipers from ecs) and the e90 328i calipers for the rear. Same brakes, lower price.

By the way, I did this exact retrofit on my e87 118i.

Yep, I decided to go this route. Using the ATE calipers, I was able to build an entire rear caliper set for under $300 with all the hardware. Now I just need to decide if I want the OEM front kit which is still available or the upgraded set with 2-piece rotors. The Performance front rotors are basically 2-piece, except that they're riveted together permanently.

I went with a pair of durago rotors for mine and I am very happy so far (2 piece identical to the OEM 2 piece) Model DuraGo BR900986. I don’t push my 118i like my 335i but they do great!
