Rear adapter plates backordered, will be about 6 weeks froom 7/27. Spacer plates still in stock. If you order tehy will ship when they are ready. 

A perfect pairing for our M3/M4 front brake kit. Our product options make it possible to fit the 370x22mm rotors and Brembo calipers from the F8x M3/M4 to any E8x or E9x. These rear brakes are massive compared to non-m brakes. The increased rotor size gives this brake package much more thermal capacity. This helps your brakes stop better, for longer. With the front and rear kit on our 650hp 1M clone we no longer have any fading issues at the track.

Depending on what car you have, you'll need a different combination of parts

NOT COMPATIBLE WITH LCI E90/E91 MODELS. E92, etc LCI works. 


E8x Non-m (128i,135i, etc): The most simple. The adapter plate kit lets you simply bolt on the brake package and go. 


E9x Non-M (325i, 335i, etc): Will either need to change to E9x M3 knuckles and use the spacer plate option, or make your car 10mm wider on each side by changing your hubs to those on the 135i and use our rear adapter plate kit. We do not recommend shaving down the knuckle as seen online. Changing the rear hubs is basically the same as replacing your wheel bearings. 


M Models (1M and M3): All you need is our spacer plate option. 

 

Both kits come with all the hardware required.
