Miata coilover suspension kits include springs and threaded body shocks (or
sleeves with the GC conversion kits) to give YOU precise and independent
control over the height of each corner of your Miata. The threaded body
means that the outside of the shock tubes (or sleeve with the GC kits) are
threaded like a bolt and this allows the threaded spring perch to be moved
up or down to fine-tune the ride height. Want it level? You can do it.
Want some rake? You can set whatever height and rake you want. We even
have customers in heavy snow states who use our Miata coilovers to raise
their Miata for winter driving and lower it for summer. And Miata coilovers
give you the ability to precisely corner balance with your weight in the

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.
