Supplied boxed as a set of two.
Brian's Application Notes: A nice redesign of the factory mount it manages to come in a few ounces lighter on weight despite being much stiffer, thanks to slightly less metal in the cradle but substantially more rubber, and that rubber is higher durometer. We used a set in our forum Project Blue 2.5 conversion to make high rpm shifts easier and more precise. Also used these in our Budget NC Project. For any NC project that is doing track and autocross but still used for a lot street driving this is the upgraded Miata engine mount choice we suggest.
In 2016 I purchased a 2008 PRHT with 88,000 miles. Within a few months I drove to Brian's shop where the world famous Rocky (in his shop) installed a giant slew of gear. This included a new MZR 2.5, triple pass radiator, Happy Meal Combo, upgraded brakes, Progress Coils and Sways, full stainless exhaust from ceramic headers to the lovely Super Q, and more. Since then with the continued support of Sean, Ryan and Brian I added Hypergrams, a recovery tank and other goodies.
One thing we forgot were motor mounts. A big mistake. Now with 122k on the original mounts I was having serious issues. Last March 2020, just as Covid was starting to rip apart the world, my car was falling apart. It sounded like the exhaust system was slamming the chassis, like a heat shield was rattling off the car. I was scared to drive it. Numerous shops could find nothing loose.
In Feb of 2021 I installed competition motor mounts and the car was like new. (Thanks Ryan) Everything was quiet and tight. It was as if I had installed a new transmission. The car never performed like this since I bought It. It became the tight slot car I always wanted. This of course was due to the fact my 88,000 mile Miata had worn mounts that must have seamed "Good Enough". My engine was banging on the chassis! However, the introduction of the 2.5 and all of the extra goodies just finished off the mounts in the following years.
These new mounts have completely changed the character of my car. I now want to drive it all of the time. My transmission never shifted as smooth and tight as it does today. Thanks to everyone at Goodwin for supporting our Miatas, especially NCs. If you have miles on your Miata you owe it to yourself and your car to change your mounts. I can think of no modification that improved my driving experience more than these new competition mounts.
