Thank you. You have rated this product.

Having issues getting third gear when pushing your Miata hard? Experiencing excessive wheel hop leaving the start at autocross? It might be worn out engine mounts or differential mounts!

We also have seen folks having issues getting their new exhaust to line up during installation and it usually turns out that one motor mounts is failing! This causes their motor to drop to one side, taking entire exhaust system along with it. These mounts are genuine Mazda Motorsports 75 durometer rubber engine and differential mounts which are 40% stiffer than stock 55 durometer mounts. The result is much cleaner shifts, reduced wheel hop and bushings that last longer. These are a perfect match for a dual purpose car that you do not want increased noise, vibration and harshness from polyurethane mounts.

These are a simple bolt in replacement, price is for a pair of engine mounts and a pair of differential mounts.

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. Those tracking or autocrossing their Miata should replace these motor mounts every year. 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.

Thanks for making this work and providing great customer service! I had a full weekend with the install, but man was it worth it. The flywheel was such a good choice. I can't believe how much easier rev-matching down shifts are. The ACT is surprisingly easy to live with, even with the engagement point very low. I'll tackle that when it stops raining. Thanks again for making this happen this weekend.

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.
