Brembo 1B2.8015A3 GT Piston Big Brake Kit Front Slotted - 4 355mm

The Brembo Gran Turismo (GT) 4 Piston Big Brake Kit is engineered specifically for the 2001-2006 BMW M3 (E46), delivering exceptional stopping power for both daily driving and aggressive track use. This complete front brake upgrade features 355x32mm 2-piece slotted rotors with silver anodized finish calipers, designed to bolt directly onto your vehicle's original suspension without modifications to the brake master cylinder or ABS system.

Complete Kit Includes:

• Fixed aluminum 4-piston brake calipers in silver finish
• Two-piece vented and slotted brake rotors (355mm diameter x 32mm thickness)
• High-performance brake pad set
• Stainless steel braided brake lines
• Aircraft-quality mounting brackets and hardware

Key Features:

• Two-piece rotor design reduces unsprung weight and provides better thermal management
• Slotted rotor surface evacuates brake dust and gases for consistent pedal feel
• Corrosion-resistant coating on rotors prevents rust and provides aggressive appearance
• Fixed caliper design eliminates flex for superior pedal response and modulation
• Fully compatible with factory ABS and brake proportioning systems
• Direct bolt-on installation with no modifications to suspension components

Brembo Gran Turismo systems are designed as a complete front brake upgrade for vehicles with high braking demands. The larger rotor diameter and increased caliper piston area provide significantly improved heat dissipation and clamping force compared to stock braking systems. For a matched appearance, Brembo Sport rotors are available separately for the rear axle.

Important: Proper wheel fitment verification is critical before installation. Wheel diameter, offset, and spoke design must provide adequate clearance for the larger caliper and rotor assembly. Minor modification to OE components may be required.
