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

This is the Brembo GT Big Brake Kit for the front of your 1987-1991 BMW M3 (E30). It's designed to give your M3 a significant upgrade in stopping power and heat management, which is crucial for spirited driving or track use. The kit features four-piston calipers and larger rotors that replace your stock setup, offering a more robust and responsive braking experience.

At the heart of this kit are the Brembo GT calipers, cast from aluminum for a good balance of strength and weight. These calipers house four pistons, which apply more even pressure across the brake pad surface compared to smaller, single-piston calipers. This results in better pad wear and more consistent braking force. The rotors are a substantial 330mm in diameter and 28mm thick, providing a larger surface area for heat dissipation. They are also slotted with Brembo's Type-1 pattern, which helps to vent gases and dust away from the pad surface, maintaining optimal friction even under heavy use. The rotors are a two-piece design, with a cast iron braking surface and an aluminum hat, which helps to reduce weight and manage heat transfer.

This kit is a comprehensive solution for anyone looking to seriously upgrade their E30 M3's braking performance. It includes everything you need to get these powerful calipers and rotors mounted up, assuming your wheels have enough clearance. Because this is a significant brake upgrade, it's always a good idea to check your wheel specifications to ensure clearance for the calipers and rotors before installation. This kit is a solid choice for track days or for drivers who demand the best from their braking system.
