PARAGON Rotor Rings - Ginetta G55 (GT4) - Front, 378 x 32mm
Paragon replacement rotor rings for the Ginetta G55 Standard, Super Cup and GT4. They bolt to the car's original aluminium front hats, so you can renew worn rings without buying complete rotors. Sold as a left and right pair with new attachment hardware for both rotors.
The slotted rings are cast from CM-250 high-carbon alloy iron, heat treated and CBN machined, with directional vanes that run up to 30% cooler than OE rotors. Lateral run-out is held within 0.03mm and each ring is balanced within 2 g.
Note: Fits the original aluminium hats on the Ginetta G55 Standard, Super Cup and GT4 front brakes. Cross-references Ginetta G50-I0057 / G50-I0058. Installation by a professional is recommended.
