Race-Grade Front Braking for the Original Mopar 4-Piston SRT8 Platform
The Rotora RP.11490.4 H9 Super Graphite Metallic front brake pad is Rotora's highest-performance OEM-caliper compound, engineered for circuit racing and sprint-endurance events on the 4-piston Brembo OEM front calipers of the Dodge Challenger SRT8, Dodge Charger SRT8, Dodge Magnum SRT8, and Jeep Grand Cherokee SRT8. Operating in a temperature window of 200 to 800 C with a friction coefficient of 0.42 to 0.59, the H9 delivers absolute fade resistance and a stable, repeatable friction curve under sustained race-level braking loads. The RP.11490.4 is a direct-fit pad for the factory 4-piston caliper with no modifications required, and every unit is built using the same compound material standards as Rotora's full brake kit program. For SRT8 owners who compete and need the peak of what an OEM-caliper pad can deliver, the RP.11490.4 is the answer.

About Rotora
Rotora manufactures high-performance brake systems and pad compounds trusted by professional racing teams and serious track drivers worldwide. The H9 Super Graphite Metallic is the peak formula in Rotora's OEM-caliper pad lineup, developed for applications where brake temperatures remain elevated throughout an entire session and fade resistance is the primary requirement. Every Rotora pad is built using the same material standards as its full big brake kit program, giving RP.11490.4 customers genuine race-grade compound quality in a direct-fit format for the factory 4-piston SRT8 caliper.
Frequently Asked Questions
What vehicles does the Rotora RP.11490.4 fit?The RP.11490.4 fits the 2008 to 2014 Dodge Challenger SRT8, the 2006 to 2014 Dodge Charger SRT8, the 2006 to 2008 Dodge Magnum SRT8, and the 2006 to 2010 Jeep Grand Cherokee SRT8. All share the 4-piston Brembo OEM front caliper that the RP.11490.4 is designed for.
Is the H9 suitable for street use?No. The H9 has a minimum operating temperature of 200 C, meaning it performs well below capability during cold street driving. This compound is intended for track and race applications only. For street or mixed use, the H2 (RP.11490.1) or H6 (RP.11490.2) compound is the appropriate choice.
How does the H9 differ from the H8 for race use?The H9 has a minimum operating temperature of 200 C versus 0 C for H8, and a slightly higher peak friction coefficient of up to 0.59 versus 0.58 for H8. The H9 is optimized for sustained circuit sessions where temperatures stay high throughout the event, while the H8 provides broader cold-performance capability for mixed use. For dedicated race weekends, the H9 is the correct selection.
Is the 4-piston SRT8 caliper the same as the 6-piston SRT caliper on 2015-plus models?No. The 2015 and later Challenger, Charger, and Grand Cherokee SRT models use a larger 6-piston Brembo front caliper. The RP.11490.4 is designed for the 4-piston caliper used through 2014 on the Challenger SRT8 and through 2010 on the Grand Cherokee SRT8. For 2015-plus models, use the RP.14051 series pads.
Does the Dodge Magnum SRT8 use the same caliper as the Charger SRT8?Yes. The 2006 to 2008 Dodge Magnum SRT8 and the 2006 to 2014 Dodge Charger SRT8 share the same 4-piston Brembo front caliper, making the RP.11490.4 a direct fit for both models.
What is the correct bedding procedure for the H9?Because the H9 requires elevated temperatures, a standard street bedding procedure is insufficient. Perform progressive high-speed decelerations on a closed course, starting at moderate speeds and working up to race speed across multiple passes with full cool-down intervals. Follow the specific Rotora H9 bedding protocol included with the pad set before competition use.
How often should H9 pads be inspected during a race event?Rotora recommends inspecting pad thickness between every track session. Race compounds wear faster under sustained high-temperature use than street pads. Always measure remaining thickness against the minimum limit on the backing plate and replace the set before reaching the wear indicator, not after.
Can I run the RP.11490.4 with the factory SRT8 rotors?Yes, though H9 compounds are harder on rotors at race temperatures. Inspect rotor thickness and surface condition before fitting and between each track session. Replace any rotor that has reached minimum thickness or shows significant heat cracking before further race use.
Installation Instructions
- Safely lift and support the vehicle on jack stands and remove the front wheels.
- Remove the caliper retaining bolts and carefully slide the caliper off the rotor. Suspend with a wire hook to avoid stress on the brake hose.
- Remove the old pads and all hardware clips or shims from the caliper bracket.
- Clean all bracket contact surfaces and sliding pins with brake cleaner.
- Using a C-clamp or piston retraction tool, carefully compress all four caliper pistons evenly back into the bore.
- Install the new RP.11490.4 pads into the bracket, ensuring all clips are fully seated.
- Reinstall the caliper and torque all bolts to factory specification.
- Reinstall the wheel and torque lug nuts to specification.
- Pump the brake pedal firmly until full pedal feel is restored before moving the vehicle.
- Top off brake fluid and perform the race-specific H9 bedding sequence before competition use.
