The Innovative Mounts Billet Rear Differential Mount Kit (B90755) is a high-performance replacement differential mounting solution designed for the 2000-2009 Honda S2000 (AP1/AP2) equipped with F20C and F22C1 engines and manual transmissions. Engineered to improve rear differential stability, reduce unwanted drivetrain movement, and enhance power delivery, this mount kit is an excellent upgrade for street performance, track racing, and high-horsepower applications.

Manufactured from precision-machined billet aluminum, these mounts offer exceptional strength, durability, and a premium performance-oriented appearance. Innovative Mounts' specialized polyurethane bushings help control excessive differential movement during acceleration, deceleration, and aggressive driving while providing a more direct and responsive driving experience.

Unlike factory rubber differential mounts, which can deteriorate over time and allow excessive movement under load, the Innovative Mounts B90755 kit provides a stronger, more controlled mounting solution. Whether restoring a worn factory mounting system or upgrading a modified S2000, this kit delivers improved drivetrain stability and dependable performance.

Higher durometer bushings provide increased drivetrain stability but may transmit additional noise, vibration, and harshness (NVH) into the vehicle. Verify the available bushing options when ordering.

Common Reasons for Replacement

• Worn Factory Differential Mounts: Deteriorated rubber bushings can allow excessive rear differential movement.

• Excessive Drivetrain Movement: Factory mounts may struggle to control differential movement during aggressive driving or high-horsepower operation.

• Wheel Hop During Acceleration: Upgraded differential mounts help reduce unwanted movement that can contribute to wheel hop.

• Drivetrain Clunking: Worn or damaged differential mounts may contribute to clunking noises during acceleration, deceleration, or gear changes.

• Reduced Drivetrain Responsiveness: Excessive movement in factory mounts can create a less direct feeling during power delivery.

• Forced-Induction Upgrades: Turbocharged and supercharged S2000 builds benefit from improved differential stability.

• Track or Racing Preparation: Performance mounts provide more consistent differential positioning under demanding driving conditions.

• Differential Mount Failure: Replaces damaged or deteriorated factory mounting components with stronger billet aluminum alternatives.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a 2000-2009 Honda S2000 AP1/AP2 equipped with a compatible factory-style rear differential mounting configuration.

2. Safely Raise and Support the Vehicle: Use appropriate lifting equipment and jack stands to provide safe access to the rear differential assembly.

3. Support the Rear Differential: Properly support the differential before removing factory mounting components to prevent unintended movement or damage.

4. Remove Factory Differential Mounts: Carefully remove the original differential mounting components following the appropriate factory service procedures.

5. Install Replacement Mounts: Position the Innovative Mounts billet components in their designated mounting locations, ensuring proper alignment.

6. Inspect Mounting Hardware: Verify that all mounting fasteners, brackets, and contact surfaces are compatible and in good condition.

7. Torque Mounting Hardware: Tighten all mounting hardware according to the applicable manufacturer specifications.

8. Inspect Differential Clearance: Verify proper clearance around the differential housing, driveshaft, axles, exhaust components, and surrounding suspension components.

9. Account for Additional NVH: Performance polyurethane differential mounts are stiffer than factory rubber mounts and may transmit additional drivetrain noise and vibration into the cabin.

10. Professional Installation Recommended: Installation by an experienced automotive technician is recommended to ensure proper fitment, alignment, and differential support.
