Thank you. You have rated this product.

For those racing stock class autocross, we offer just the blocks and bolts of the Racing Beat Sway Bar Brace kit (the blue arrow points to the blocks).

Please be careful to select year...this is the set for ALL years except those 90-95 Miatas with power steering. White cross brace seen here NOT included. IF YOU HAVE POWER STEERING IN A 1990 through 1995 Miata please see the OTHER version of this blocks and bolts kit at the bottom of the page.

BRIAN'S APPLICATION NOTES: IF you want to install protection that you can forget (but is much more work to install) see our product item 20-1021 HD Mounts. These blocks and bolts are MUCH easier to install but need to be checked for tightness at least once a year.

Watch the Video by STR Racer Mike Heinitz. First video is WITHOUT protecting the mounts and the deflection under load is half an inch, which will eventually tears those mounts!

Now watch the second video by STR Racer Mike Heinitz and notice that with the blocks/bolts installed the flex is greatly reduced!

As you can see, i placed another order for more parts for my car. I wanted you to know that I'm pleased at how quickly the wheels/tires came, and the radiator too. Great service and response time.

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.
