Innovative Mounts 90-05 NSX Mount Kit C32 - Part #80550
NSX mounts are not something the aftermarket rushed to build, so a 20 to 35 year old car with sagging factory mounts usually has no good option. This is the replacement kit for a C32 powered NSX with a manual transmission, and on a mid-engine car with the drivetrain right behind your shoulder, the difference between good mounts and tired ones is not subtle.
What It Is and Why It Works
Tapered polyurethane bushings replacing the factory fluid filled mounts. On an NSX the engine sits transversely behind the cabin, so drivetrain movement transmits into the chassis differently than it does in a front drive car: you feel it as the whole rear of the car shifting on throttle transitions rather than as wheel hop. Holding the C32 still cleans up that motion and sharpens throttle response.
75A is the durometer for a street driven NSX, which describes nearly all of them. 85A for track use. 95A is a race durometer, and in a car this well insulated it would be an odd choice unless the car lives at a circuit.

This kit is for C32 powered cars with a manual transmission. Innovative also builds a K-series swap kit for the NSX, part 81550, which we already carry.
What to Know Before You Buy
Verify the engine before ordering. The NSX ran the C30 through 1996 and the C32 from 1997 in the six speed cars, and Innovative lists this kit for C32 applications. If your car is an early C30, confirm fitment with us before buying rather than after.
Get the car on a lift and look before you order anything. NSX mount access is not a driveway job, and if the car is going up anyway it is worth inspecting everything back there at the same time.
Stay at 75A unless the car is tracked. An NSX is a refined car and its owners notice noise that a Civic owner would never register. Mounts cannot be returned once they have been bolted down.
