FAQ
What is the RSK.720.01?
The RSK.720.01 is the Rotora Super Challenge rear big brake system for the 2003-2010 Dodge Viper. It features a 4-piston RSK monoblock aluminum caliper with oversized 2-piece directional rotors in natural anodize finish, available in slotted or drilled disc configurations.
Does the RSK.720.01 fit all Viper generations?
The RSK.720.01 is designed specifically for 2003-2010 Dodge Viper models. Later Viper generations use a different rear hub and bracket interface and require a different part number.
Should I pair the RSK.720.01 with the RSK.719.01 front kit?
Yes. Rotora engineers the RSK.720.01 rear kit to balance with the RSK.719.01 front kit for consistent brake bias and predictable pedal feel across all four corners.
What disc configuration should I choose for the Viper rear?
Slotted rotors deliver consistent performance across a wide temperature range and suit spirited street driving and track days. Drilled rotors offer excellent initial bite and reduce unsprung weight. For extended track sessions, slotted is generally recommended.
Does the RSK.720.01 include brake pads?
Yes. A set of high-performance street brake pads is included with every RSK.720.01 kit.
Will this kit affect my Viper's ABS or parking brake?
No. The RSK.720.01 replaces only the caliper, rotor, and brake line assembly. The parking brake mechanism and ABS sensors are not modified.
Is installation of the RSK.720.01 straightforward?
The RSK.720.01 is a direct bolt-on kit using factory mounting points. All brackets, hardware, and brake lines are included, and no machining is required.

How does the SKU suffix work on the RSK.720.01?
