BMW X3M F97 and X4M F98 Front GT Performance Brake Package by Brembo — 8‑Pot Calipers, 412 x 38 mm Two‑Piece Discs

Transform the braking on your S58-powered BMW X3M and X4M with Brembo’s GT Street front axle performance brake package. This premium setup delivers serious stopping power for fast-road driving and occasional track days, pairing 8‑piston cast monobloc aluminium calipers with massive 412 x 38 mm two‑piece brake discs in your choice of cross‑drilled or slotted surfaces. If you are searching for a front brake conversion for the F97 X3M or F98 X4M that provides stronger bite, superb pedal feel and consistent performance under heat, this is the upgrade enthusiasts trust.

We have installed and used these kits on our own builds and many customer cars. Feedback is outstanding: sharper initial response, smooth modulation, excellent heat management and fade resistance, plus a refined street experience thanks to the included anti‑noise components. This is the go-to front brake upgrade for BMW X3M and X4M owners who want confidence on B‑roads and stability during repeated high‑speed stops.
