Brembo GT 4-Piston Front Big Brake Kit - BMW M3 (E46) - 355mm
A Brembo GT front upgrade for the E46 M3. Silver four-piston calipers and 355 x 32mm two-piece floating rotors replace the factory sliding calipers, adding clamping force and heat capacity so the brakes stay consistent through a full track session.
Both kits have silver calipers. Choose Type 3 or Type 3L slotted rotors.
Note: These calipers and rotors are larger than the factory brakes, so check that your wheels clear them using Brembo's clearance drawing in the photos before ordering. Installation by a professional is recommended.
