Rear Brake Confidence for the Original American Supercar
The early Dodge Viper demanded respect on every drive, and the RFK.720.01 Rotora Street Challenge Rear Brake System gives the 2003-2010 generation the rear brake upgrade it deserves. A 4-piston RF404 forged aluminum caliper paired with a 355x32mm 2-piece floating rotor replaces the stock rear setup with hardware built to handle repeated hard stops without fade.
Key Features
- 4-piston RF404 forged aluminum caliper for strong, consistent rear clamping force
- 355x32mm 2-piece floating rotor for reduced weight and improved heat dissipation
- Direct bolt-on fitment for the rear axle, no permanent modification required
- Available in 10 caliper finishes including Natural Anodize (Zinc)
- Slotted or Drilled rotor face options to match braking preference
- Stainless steel braided brake lines included for firmer pedal feel
- Performance brake pads matched to the RF404 caliper included
