A 15-inch GT rotor assembly and red AERO6 caliper are supplied for each front corner, together with aluminum hubs, bearing parts and mounting hardware. BP-20 pads suit the documented configuration, while the separate hat and rotor ring retain the specified two-piece construction.

The company designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, with each part selected to match the complete brake system.

Fitment & Compatibility

This package requires the Wilwood ProSpindle installation shown in DS1100, rather than a general factory-disc spindle. Check the correct drop or standard-height assembly, +0.68-inch hub offset, wheel bolt pattern and complete brake-to-wheel clearance. Hoses are not included.

For a fitment check, give PMB Performance the vehicle details and the actual brake and suspension hardware. Our team has over 20 years of experience working through parts compatibility.

Check the Installation instructions for the full assembly and wheel-clearance requirements.
