The rear brakes shaved off 1.4lbs per corner due to the lighter 11.2lb OEM caliper. The rear PFC caliper bracket was marginally lighter, weighing in at 8.2lbs for the caliper and bracket assembly. A Brembo e-brake kit was modified to fit the wider PFC rotor as well as a custom bracket.
All-in, the massive PFC brake package ended up just slightly lighter than the OEM brakes it replaced. That’s not a bad tradeoff for delivering more than enough stopping power for the 800hp+ FXMD Time Attack NSX that used 300/310 sized racing slicks.
With slight modification, we were able to stuff these gigantic 14” PFC brakes under a set of 17” Volk CE-28 wheels.
The brakes fit much easier under a new set of 18×8.5” Advan RSII wheels wrapped in 235/40-18 Nitto NT05 tires. To be honest, 13” brakes look a bit small behind 18” wheels, so we were quite happy with the visual looks of the setup in addition to the performance.
A new set of 19×10” Advan RSIIs now reside on the rear of the NSX, wrapped in 275/35-19 Nitto NT05 tires. This wheel and tire stagger is within the OEM stagger tolerances and enables far more tire options to choose from. The PFC brakes and e-brake setup bring a far more modern look and significantly greater technology to our 30-year-old platform.
