Thank you. You have rated this product.

These Competition Diff Mounts from I.L.Motorsport are born from the extensive testing in the European MX5 Race Series.

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 Diff 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 twist 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.

I have to say that your website is one of the cleanest, most functional and easy to use. There are a lot of independent part sellers that have horrible websites and it was a joy to use yours and even explore the customer car gallery and the good win build page. Thank you for a great experience.

Wanted to say thanks. The exhaust system fit perfectly, no drone at steady throttle, but a nice sound winding thru the gears. And it does sound a lot like my old Alfa. The Racing Beat lowering springs are just right. Appreciate the tech advice and the service.
