Thank you. You have rated this product.

From our friends at Konig comes this new heat treated 15x8 with 25mm offset and 4x100 bolt pattern WIDE fitment Miata wheel. Weight just 13.2 pounds. YES, this aggressive fitment requires a substantial fender lip roll for Miata fitment...but worth it for the same FAST offset that has proven fastest in Spec Miata. Fits brakes on all 1990 through 2005 Miatas...and fits our BIG BRAKE kits!

Brian's Application Notes. Notice that we have both a 20mm version and 25mm version. Obviously the 25mm version is an easier fit, but will still require fender lip roll. Also, the 25mm will have lower steering effort than the 20mm. Finally, please notice that the 20mm has polished lip while the 25mm is all silver powder coat with clearcoat over. Spoke shape and lip width are the same for both 20mm and 25mm (the 5mm difference is made by shaving down the pad on the back of the wheel).

Takes an optional 73mm hubcentric ring available on this website (73/54 for Miata).

MOUNTING NOTES: The Drop Center on this wheel is several inches from the top lip, making it difficult to mount stiff race tires on this rim unless you flip the wheel on the mounting machine.

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!)
