Thank you. You have rated this product.

KONI has a long-standing reputation in racing circles as a manufacturer of high performance, top quality shocks and struts. KONI uses superior materials in the manufacture of their components to ensure significantly improved handling and excellent durability. These externally adjustable shocks will improve the handling performance of your car!

Brian's application notes: As with NC application, so it is with ND application that you are changing from stock high pressure monotubes to lower pressure twin tubes. On the NC this change added half an inch of lowering of the car, we found about the same lowering with our install on our Fiat 124. Picture below is our Fiat 124 with our Progress Springs and KONI SPORT Shocks. Super impressed with the improvement these brought to our Fiat 124, car is much more composed over the road, driver's control at the limit is more predictable and confident. With help of these Koni Sport shocks our Fiat 124 was in the trophies at our first SCCA event with this project.

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.
