Designed as a performance replacement for the factory engine and transmission mounting system, the Innovative Mounts 90750 provides increased drivetrain stability, reduced excessive engine movement, and improved throttle response compared with worn factory rubber mounts.

The Honda S2000's high-revving F20C and F22C engines deliver exceptional performance, but deteriorated factory mounts can allow unwanted drivetrain movement during aggressive acceleration, deceleration, and shifting. This movement can contribute to drivetrain clunking, inconsistent engine positioning, and a less connected driving experience.

The Innovative Mounts 90750 replaces the factory mounting components with durable steel assemblies featuring high-performance polyurethane bushings. These bushings are designed to resist excessive drivetrain movement while providing a degree of vibration isolation.

Unlike the billet aluminum B90750 kit, the steel 90750 package includes the rear transmission mount, providing a coordinated upgrade for the driver-side engine mount, passenger-side engine mount, and rear transmission mounting position.

Featuring CAD/CAM-engineered mounting geometry, stress-analyzed components, and Innovative Mounts' no-tear polyurethane bushing design, the 90750 is an excellent choice for daily-driven S2000s, naturally aspirated performance builds, supercharged and turbocharged applications, and dedicated motorsport vehicles.

Important: The Innovative Mounts 90750 is designed for factory-style F-Series engine and manual transmission applications. It is not a complete K-Series engine swap conversion kit.

Available Polyurethane Bushing Hardness Options

75A – Black – Street / Performance

The softest available bushing option for the 90750.

Recommended for daily-driven and performance-oriented Honda S2000 applications where improved drivetrain stability is desired while retaining some vibration isolation.

Manufacturer horsepower guidance: approximately 250–400 HP.

85A – Grey – Performance / Race

Provides increased drivetrain rigidity for modified engines, aggressive driving, and competition applications.

Manufacturer horsepower guidance: approximately 400–500 HP.

95A – Red – Extreme Race

The stiffest available polyurethane option, intended for high-output engines and dedicated racing applications.

Manufacturer horsepower guidance: 500+ HP.

These horsepower ranges are general manufacturer bushing selection guidelines rather than guaranteed load ratings or minimum horsepower requirements.

Important: Increasing bushing hardness generally increases noise, vibration, and harshness transmitted into the vehicle cabin. The 75A option is typically the most appropriate starting point for a street-driven S2000.

Common Reasons for Replacement

• Cracked Factory Rubber: Aging rubber can deteriorate and allow excessive engine movement.

• Deteriorated Factory Mounts: Original mounting components may lose their ability to control drivetrain movement.

• Leaking Factory Mounts: Fluid-dampened mounting components can lose effectiveness when damaged.

• Separated Mount Bushings: Worn factory mounts may develop excessive movement under load.

• Excessive Engine Rocking: Firmer polyurethane helps control unwanted drivetrain movement.

• Clunking During Acceleration: Worn mounts may allow excessive movement that results in noticeable drivetrain noise.

• Clunking During Gear Changes: Excessive drivetrain movement can contribute to noticeable movement during shifting.

• Reduced Drivetrain Stability: Performance polyurethane helps maintain more consistent engine and transmission positioning.

• Performance Engine Upgrades: Modified F20C and F22C engines can benefit from firmer drivetrain mounting.

• Track and Racing Applications: Provides increased mount rigidity for demanding driving conditions.

• Coordinated Mount Replacement: Replaces the three primary mounting positions together rather than upgrading only one mount.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a 2000–2009 Honda S2000 AP1 or AP2 equipped with a compatible F-Series engine and manual transmission.

2. Inspect the Existing Mounts: Check the factory engine and transmission mounts for cracked rubber, fluid leakage, separation, corrosion, or excessive movement.

3. Support the Drivetrain: Properly support the engine and transmission before removing the factory mounting components.

4. Remove the Factory Mounts: Follow the applicable Honda S2000 factory service procedures.

5. Inspect Mounting Locations: Check the chassis, subframe, transmission crossmember, and mounting brackets for damage or corrosion.

6. Install the Driver-Side Engine Mount: Position the Innovative Mounts 90710 in the factory driver-side mounting location.

7. Install the Passenger-Side Engine Mount: Position the Innovative Mounts 90720 in the factory passenger-side mounting location.

8. Install the Rear Transmission Mount: Position the Innovative Mounts 90730 at the factory rear transmission mounting location.

9. Verify Mount Alignment: Ensure all mounts and brackets are properly aligned without excessive preload or binding.

10. Install the Required Hardware: Use the hardware specified by Innovative Mounts and reuse applicable factory fasteners where instructed.

11. Torque Mounting Fasteners: Follow the Honda S2000 factory service manual and Innovative Mounts installation instructions.

12. Inspect Drivetrain Clearance: Verify that the engine, transmission, driveshaft, exhaust, and surrounding chassis components have adequate clearance.

13. Check for Additional Vibration: Some increase in noise, vibration, and harshness is normal when upgrading from factory rubber mounts to performance polyurethane.

14. Perform a Final Inspection: Verify proper mounting alignment and secure hardware before operating the vehicle.

15. Recheck After Initial Use: Inspect the mounts and mounting hardware after the initial driving period.

Important: Innovative Mounts advises that mounts showing bolt impressions from installation cannot be returned or exchanged. Confirm fitment before installation.

Professional installation is strongly recommended.
