AP Racing Radi-CAL ll complete brake kit complete with 6 Pot front and 4 Pot rear calipers, 12 groove discs, AP Racing brake pads and a full fitting kit including bells, brackets and fasteners.
The forged 4 and 6 Piston calipers incorporate AP's patented technology allowing the road user to experience the superior performance that Rad-CAL™ offers.
In addition the calipers incorporate all the features demanded by the road market including, dirt seals, an attractive painted finish and noise abatement solutions.
Offering less mass, improved rigidity and better cooling characteristics than conventional and World Radi-CAL 1 Brake caliper designs, the Radi-CAL™ concept represents a major innovation in braking technology when it was introduced.
The Supertec Racing kit is carefully selected based on our road and track testing experience to work with the Nissan Skyline GTR brake system using the BM57 17/16” (27mm Piston) brake master cylinder as used on the R33/34 GTR models.
Both the adapter brackets and lightweight bells are made from billet 7075 T6 grade aluminium. Not to be confused with cheap kits, Supertec Racing Kits are designed manufactured to the highest standards in the UK with FEA (Stress analysis and simulation) to ensure the highest strength and reliability.
In order to maximise stopping power and help cooling by dissipating unwanted heat while still operating with in the correct temperature window - we have opted for 380x36mm front discs and 355x32mm.
One piece front and rear lightweight bells with reduced diameter for compatibility with Skyline e-brake diameter.
Kit is compatible with R32, R33, R34 GTR models. Will also fit Nissan Silvia (S13/14/15) and 300ZX.
