Product details

Fitment & Compatibility
Match this component to the documented Nissan 240Z brake conversions. Confirm the mounting stack, center location and rotor hardware; vehicle model alone does not establish compatibility with a modified brake system. Select the rotor and attachment hardware separately for the documented assembly. Follow the installation drawing for engagement and clearance at every mounting point.
