Polyurethane differential bushings

Stiffer differential mounts improve your shifting.

Made in the USA

Availability: In stock



The differential is mounted in the car with some surprisingly flexible rubber bushings. Replacing these with stiffer Prothane polyurethane will cut down on differential movement, which actually makes your shifting more precise due to the way the Miata's drivetrain is mounted. There's an increase in vibration, but most people don't mind it at all. A definite plus for competition cars - you don't want to hit 5th instead of 3rd in the heat of competition!

Bushings fit 1990-2005 only.

Worth the effort to install it.
If you’ve ever tried to do a launch and the only thing that moved was your shifter, you need this. On a 28 year old car, the difference is night and day when it comes to the firmness of the entire vehicle. The acceleration becomes smooth and the whee hop is reduced to almost none.
