Matched Rear Carbon-Ceramic Stopping Power for the Dodge Viper
The Rotora RFKC.720.01 brings carbon-ceramic performance to the rear axle of the Dodge Viper, pairing a 4-piston forged caliper with a 355x32mm carbon-ceramic disc. Carbon-ceramic construction sheds significant weight compared to a conventional iron rotor, lowering unsprung mass at the rear axle for sharper turn-in and more predictable rotation under trail braking. The disc holds up to sustained high temperatures without fading, so pedal feel stays consistent through long track sessions. Offered in 10 caliper finishes with a Natural Anodize option shown here, this rear system is built to complete a full carbon-ceramic setup on a Viper driven hard on street and track.
Key Features
- 4-piston RF404 forged caliper for balanced rear clamping force
- 355x32mm 2-piece carbon-ceramic (C/SiC) disc, dramatically lighter than an iron rotor of the same size
- Exceptional resistance to brake fade during sustained high-temperature track use
- Longer service life than conventional iron rotors under equivalent use
- Forged aluminum hats with floating hardware for controlled thermal expansion
- Stainless steel braided brake lines for a firm, consistent pedal
- Available in 10 caliper finishes
- Special Order item built to confirmed fitment before shipment

About Rotora
Rotora designs and manufactures performance brake systems for street and track applications, including forged billet calipers and carbon-ceramic disc platforms such as the RFKC.720.01. Rotora carbon-ceramic kits are engineered to reduce rotating and unsprung mass while extending service life beyond conventional iron rotors, giving Dodge Viper owners a braking package suited to demanding driving conditions.
Frequently Asked Questions
What is the RFKC.720.01?
The RFKC.720.01 is a Rotora rear carbon-ceramic brake system for the Dodge Viper, built around a 4-piston RF404 forged caliper and a 355x32mm carbon-ceramic disc for reduced weight and sustained high-temperature performance.
Does this kit include brake pads?
No. This carbon-ceramic system ships without pads, so owners can select a compound matched to their driving use.
How much weight does a carbon-ceramic disc save versus iron?
Carbon-ceramic discs are dramatically lighter than iron rotors of the same diameter, which reduces unsprung mass at the rear axle and helps rotation under trail braking.
Is this system suited to daily street driving?
Yes. It is engineered for combined street and track use, though the Special Order nature of the part means most owners select it for dedicated performance builds.
Why is this listed as a Special Order item?
Carbon-ceramic discs are produced to order due to the specialized manufacturing process, so lead times run longer than standard iron rotor kits.
Does the carbon-ceramic disc resist fade on track days?
Yes. Carbon-ceramic construction maintains consistent friction and pedal feel across repeated high-temperature stops far better than iron rotors.
What caliper finishes are available?
The RFKC.720.01 is available in 10 caliper finishes, including the Natural Anodize finish shown as the primary listing image.
Will this kit fit stock Dodge Viper wheels?
Most factory wheel sizes clear this kit, though owners should confirm spoke and barrel clearance against the 355x32mm rotor diameter before ordering.
How long does a carbon-ceramic rotor last compared to iron?
Carbon-ceramic discs offer a longer service life than conventional iron rotors under equivalent street and track use, reducing long-term replacement frequency.
Can this rear kit be paired with the front carbon-ceramic system?
Yes. Pairing the RFKC.720.01 rear kit with the RFKC.719.01 front kit gives a matched carbon-ceramic setup across both axles.
Install Instructions
- Raise and support the Dodge Viper on the rear axle, then remove the wheel.
- Remove the factory caliper, bracket, and rotor from the rear hub.
- Mount the caliper bracket to the factory hub using the supplied hardware.
- Install the 355x32mm carbon-ceramic disc and forged aluminum hat assembly onto the hub.
- Set the RF404 caliper over the disc and torque to the mounting bracket.
- Connect the stainless steel braided brake line to the caliper and to the factory hard line.
- Bleed the brake system to remove air from the lines.
- Install a compatible pad compound suited to the intended street or track use.
- Check torque on all fasteners and confirm pad to disc clearance before installing the wheel.
- Bed in the brake pads following a gradual break-in cycle before hard driving.
