HI all, we are selling the kit off our E90 for the rear brakes, as we are converting it to a drag setup. This kit will include the calipers and the brackets we make already installed for a direct bolt on for the rear brakes. All you will need to source is the rear M-Performance rotor, brake pads and the pad clips. The calipers are used so they have some scratches and chips, but they are in perfect working order. $1,200 for the kit both calipers.
