This a front BBK for E90 and E89 use the F series 4 pot Brembo design with caliper brackets designed to fit E90 and E89 cars.
It uses the standard F series 4 pot brake pads.
It's a true bolt up solution. The existing dust shields will need some trimming or removal.
As its 4 pot pistons have the same total surface area the E90 E89 OE caliper has there's no increase in brake pedal travel.
