Brembo 87-91 M3 (E30) Front GT BBK 4 Piston Cast 2pc 330x28 1pc Rotor Drilled-Black

If you're looking to significantly improve the stopping power and heat management of your 1987-1991 BMW M3 (E30), this Brembo GT Big Brake Kit is a solid choice. This kit replaces your factory front brake components with a much larger and more capable setup, designed to handle the demands of spirited driving and track use. The core of the system is a pair of robust 4-piston calipers paired with substantial 330x28mm two-piece rotors, offering a much larger swept area and greater thermal mass than stock.

The calipers themselves are cast from durable aluminum, featuring a 4-piston design that applies more even pressure across the brake pad surface for improved braking force and feel. These calipers are paired with 330mm diameter, 28mm thick one-piece rotors that are drilled for better heat dissipation and gas venting. The drilled pattern helps prevent pad glazing and keeps braking performance consistent, even under heavy use. This kit is designed as a direct replacement for the front axle, making installation more straightforward than custom setups. You'll notice a significant difference in pedal feel and fade resistance, especially during repeated hard stops.

When installing this kit, it's important to ensure you have adequate clearance within your wheels for the larger calipers and rotors. We recommend consulting the manufacturer's installation guide for specific details on brake line connections and caliper mounting. This kit is a substantial upgrade for any E30 M3 owner looking for top-tier braking performance.
