These beautifully machined, high-strength billet aluminum hats are used on our Lightweight Brake Rotor Assemblies (Part No. 3540).
Part No. 3542-01 fits Swift and 1983-93 Van Diemen applications (used on rotor assembly Part Nos. 3540-01, -02, and -05).
Part No. 3542-02 fits Reynard applications (used on rotor assembly Part Nos. 3540-03, -04, and -06).
Our Hardware Kit for Lightweight Brake Rotors (Part No. 3543, sold separately) is required to attach the hat to the rotor. These hats accept our Lightweight Drilled Brake Discs (Part No. 3541), Grooved Brake Discs (Part No. 3544-001), or Grooved and Scalloped Brake Discs (sold separately).
Part No. 3542-03 is a special hat used to upgrade Lola Sports 2000 to LD65 calipers with our Part No. 3545-17 or -19 vented rotors. This is a popular conversion for Lola T-594/96/98 and T89/90 & up S2s that originally used the smaller LD20 caliper and solid rotors.
