Brembo 1A4.6003A2 GT Piston Big Brake Kit BMW Drilled - 4 E30 M3 Front 330mm Red

The Brembo Gran Turismo (GT) 4 Piston Big Brake Kit is a complete bolt-on brake upgrade system engineered specifically for 1987-1991 BMW E30 M3 models. This performance brake system features 330x28mm one-piece drilled and vented rotors paired with red-finished aluminum four-piston fixed calipers, delivering exceptional stopping power for both aggressive street driving and track use.

Complete Kit Includes:

• Four-piston fixed aluminum brake calipers with red powder coat finish
• 330mm x 28mm one-piece drilled and vented front brake rotors with corrosion-resistant coating
• High-performance brake pad set
• Stainless steel braided brake lines
• Aircraft-quality mounting brackets and hardware

Key Features:

• Direct bolt-on installation to original suspension mounting points
• Fully compatible with stock brake master cylinder and ABS systems
• Cross-drilled holes feature bi-angle chamfering to reduce stress cracking under high-temperature operation
• Corrosion-resistant rotor coating prevents rust and enhances visual appeal
• Significantly larger rotor diameter improves heat dissipation and brake modulation
• Fixed caliper design provides consistent pedal feel and superior clamping force

Installation Note: This kit requires minor modification for proper fitment. Wheel clearance measurement is critical before installation to ensure compatibility with your specific wheels. The larger caliper and rotor assembly requires adequate spoke and inner barrel clearance.

Brembo Gran Turismo systems are engineered to handle the demanding conditions of high-performance driving while maintaining excellent performance for daily use. The four-piston caliper design ensures even pad pressure distribution across the rotor surface, while the drilled rotor face aids in heat dissipation and wet-weather performance.
