Brembo 00-05 IS300 Front GT BBK 4 Piston Cast 2pc 328x28 2pc Rotor Drilled-Silver

This Brembo GT Big Brake Kit starts with 4-piston calipers, a solid choice for increasing clamping force over stock. The calipers are cast from aluminum, keeping weight down while offering a strong foundation for the braking system. They are paired with 328x28mm two-piece rotors, which allow for better heat dissipation compared to single-piece designs. The rotors are drilled, helping to vent gases and moisture away from the pad surface, which can improve performance in wet conditions and under heavy braking.

The two-piece rotor design is notable because it separates the rotor ring from the caliper mounting hat. This construction helps to reduce thermal stress and can prevent rotor warping over time, especially during spirited driving or repeated hard stops. The caliper hats are typically made from aluminum as well, further reducing unsprung weight. This kit is designed to be a direct fit for the 2000-2005 Lexus IS300, meaning it replaces the factory brake components without requiring significant modifications.

When installing a big brake kit like this, it's important to ensure you have adequate clearance for the larger calipers and rotors within your wheels. While this kit is designed for the IS300, you'll want to confirm that your specific wheel size and offset will accommodate the new components. It's also a good idea to consider upgrading your brake fluid to a higher boiling point type to take full advantage of the increased braking performance.
