RoadsterSport NA/NB Competition Mounts COMBO DEAL - Engine Mounts and Diff Mounts For A Great Low Price!

This is a combo that includes our RoadsterSport competition engine mounts and also competition differential mounts. Buy them together and save! Direct replacements for the Mazda Competition engine and diff mounts, but at a fraction of the price.

Engine Mounts:

Having issues getting third gear when pushing your Miata hard? Might be worn out engine mounts. We also see folks having issues getting their new exhaust install to line up and it usually turns out that one motor mounts is failing and their motor is dropping to one side and taking entire exhaust system along with it.

For years we have sold the genuine Mazda replacement Competition Miata 75 durometer Engine Mounts that are 40% stiffer than stock 55 durometer Miata Engine Mounts. The result is much cleaner shifts and they last longer. We still sell those. BUT Mazda has now raised the price of those mounts by over 200%! That's when we decided to step in and make our own mounts. These RoadsterSport competition engine mounts are just like the Mazda units - exact same design and stiffness - but less than half the cost of the Mazda mounts.

For those who must have the Mazda genuine part, we do offer the Mazda units elsewhere on this site. But for everyone else, get the same performance and spend less!

Simple bolt in replacement.

BRIAN'S APPLICATION NOTES: In track and autocross use the factory mounts are not stiff enough to prevent driveline twist that will make it hard to shift when trying to shift quickly. If you want something that lasts even longer, see our complete upgraded mounts with urethane bushings but those are MUCH stiffer and will mean more vibrations in the dash, etc. If driving your car daily in the real world these are a perfect upgrade in our experience for crisp shifts.

Diff Mounts:

Supplied as a set of 2 these long lasting differential mounts are perfect for higher horsepower and aggressively driven Miatas... but any Miata will benefit from these durable rubber mounts that are 40% stiffer than stock. Suitable for both Street, Autocross, and Track Use. A new set of differential mounts will keep everything in line by minimizing flex, vibration and will make your Miata Feel like new again!

Brian's Application Notes: Improves the shift action! When the motor rocks over hard the transmission twists and that twists the entire driveline and that makes it tough to go from 2nd to 3rd gear when driving hard, harder mounts limit the twist and make shifting easier. Upgrade BOTH your engine and diff mounts for the best performance.
