Thank you. You have rated this product.

This version of our 6UL has been specifically engineered for the 2016+ MX5 Miata. It will fit under unmodified fenders on this car and any ride height with any suspension and support up to 235/40/17 tires (running any bigger requires fender roll)..

15.4 lbs
Low pressure cast - Flow Formed outer rim - Monoblock construction
T6 heat treated
67.1mm center bore
Double valve design
JWL approved
VIA Certified
TPMS compatible
Painted, clear coated finish
Cap included
Valves not included.

Always test wheel for adequate clearance to fenders, chassis and suspension components before using these wheels. Failure to do so could result in vehicle damage, loss of control, injury or death.

YES, fits ALL our big brake upgrades including 12.88" BBK and 4 and 6 piston caliper upgrade kits. Also clears the Brembo brakes.

Size 235/40 tire fits nicely without rolling fenders but may rub plastic fender liner at full lock and/or full suspension compression depending on how much car is lowered, amount of negative camber, suspension choice, and tire choice.

Below is 245/40/17 which requires fender roll front and rear and minimum heights of about 13.25 inch center of wheel up to fender lip or more.

I should thank you. The parts ordered have greatly enhanced my MX-5 and they were received well before I could have reasonably expected them. I'm an enthusiastic new customer. Regards, John

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.
