While most of the differential movement is restrained by the stock Power Plant Frame, stiffer side bushings can also help cut down on it. This means your shifter moves less and more power is transmitted through to the wheels. It'll also help you avoid the classic 2-5 shift.

These are similar to the Mazda Competition parts, but on a budget. Like the Mazda parts, they're about 40% stiffer than stock. They'll increase NVH slightly, but not as dramatically as solid mounts or polyurethane ones.

Fits all NA and NB Miatas. Sold as a pair, enough for one car.

A few installation notes/review

First, these bushings use the OEM Diff Mount Lower Bushing Stoppers. So when you remove the plates to take out the diff, do not burn the rubber off, grind clean and paint as you would with polyurethane or you'll need to order new ones. (Not the worst thing with 28 yr old stoppers but approx $50 each.) Second, my OEM bushings were exceptionally hard to remove and these bushings were exceptionally hard to seat. There is no way it could have been done with the diff in the car. I ended up using a ball joint bushing press with both a air wrench and also a 1/2 in drive ratchet with a breaker bar. Third, I like these bushings! My NVH actually got better since I have the noisy IRP short shifter and these bushings made the vibration better. Only had one drive but shifting (2nd to 3rd) already seems better. Just be prepared for a big job.
