Thank you. You have rated this product.

PAIR of new Engine mounts (picture shows just ONE compared to stock mount, but you get right and left mounts on this order!). For the serious Miata performance enthusiast we bring you polyurethane motor bushings for the NA and NB Mazda Miata MX5 in substantially upgraded mounts. The stock Miata soft engine rubber block in cup mounts allow a great deal of motor movement...so much that autocrossers and track day racers have complained to us for years about high speed shifts that can be vague and difficult. Our upgraded Mazda MotorSport bushings (sold elsewhere on this same website) fix just half the problem but leave the weak stock mounts (which also tend to deteriorate over time).

These COMPLETE upgrade mounts dramatically reduce motor movement for much more precise operation of your shifts and much more direct application of power to the ground.

Price is per PAIR.

BRIAN'S APPLICATION NOTES: We use a set of 70 durometer in our supercharged Miata. The 88 and 95 Durometer are so stiff as to be considered DEDICATED RACE CAR ONLY...track and autocrossers who also drive on the street should look to our 70 durometer mounts!!! First day is brutal...they take about 500 miles of use to break in! (photo shows stock piece on right). Note that even the 70 is massively stiffer than stock mounts and you can expect some vibrations in the dash, etc.

REVIEWS

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.

Hi Brian, I just bought a heatshield and a cruise control relocation bracket for my '95 Miata from you. It is in the mail now. Thanks for such fast service. (My cruise is just wrapped up in a microfiber shoprag at this time!)
