Thank you. You have rated this product.

The Gen 4 15x7 SM has been optimized specifically for the Spec Miata racing series with a thicker outer flange and thicker inner barrel to handle the special abuse of wheel to wheel banging that happens in Spec Miata Racing. This version is hub centric for the 89-05 Miata.

This wheel is 2.5lbs heavier than our standard 15x7 with a special offset just for Spec Miata Racing and lowest legal weight for the class at 13.1 pounds. 15x7

Brian's Application Notes: Racers loved the original 6UL Spec Miata wheel and it won the 2008 runoffs and they sold used for MORE than original prices. Long term feedback from that original design resulted in this new ultra strong 'gladiator' version. The wheel these are based on is roughly 10.6 lbs so they had the luxury of choosing exactly where to put the extra 2.5 lbs of material necessary to meet legal Spec Miata minimum weight so it actually helps Spec Miata owners win races and seasons on budget. The barrel and flange area are nearly twice as thick as a regular 6UL wheel with the sole focus being to increase the wheel resistance to the specific type of damage typical in Spec Miata.

Purchased the RS Max Power header and midpipe. THESE ARE TRUELY A WORK OF ART! CRAFTMANSHIP IS TOP NOTCH!! SITE PICS DO NOT DUE JUSTICE TO THESE ITEMS! I recommend Brian's site to ANYBODY with a Miata/MX 5. Brian and Co have taken a great automotive platform and elevated it to it's FULL POTENTIAL!

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.
