Show original supplier description
The Brembo 1B1.8003A is a GT Series front big brake kit engineered for superior stopping power. This kit features robust 4-piston cast 2-piece radial mounted calipers paired with substantial 355mm x 32mm 2-piece discs. The components are derived from motorsports technology, offering enhanced performance and pedal feel. It is compatible with vehicles at original ride height. Brembo recommends a minimum clearance of 3mm between the caliper and the wheel spoke or rim. Additionally, users should note that 17-inch wheels may not fit over these calipers; an 18-inch wheel setup is often required.
