Thank you. You have rated this product.

Custom made for us for the new Fiat 124 factory front brake calipers!

This high friction racing material has grown to be a very popular choice for drivers who need a pad that bites when cold for street use but also has a high temperature ceiling to withstand track use.

Drivers can still have a high friction brake pad without worry of the pad becoming too cold to be effective when the car is driven only moderately. This makes for a pad that CAN be driven on the street. But, be aware, this is a racing pad at heart - it WILL dust! All track pads do. The R4-1 has gained great popularity as an excellent auto-cross and track day pad that can do it all. Great modulation, consistent pedal feedback and the same rotor friendliness as our other carbon kevlar compounds.

BRIAN'S APPLICATION NOTES: I first drove these in Vintage racing a Triumph TR4-A....which is the same weight as a Miata. I really liked the bite of these pads and they worked great at tracks like PIR. Finally decided to try them on our 2007 supercharged track and autocross car and again the bite is great and they have low temperature performance that other race pads can't seem to deliver sufficient for use as your ONE choice for BOTH autocross and track and street driving in warmer climates.

This pad is made to order. Please allow one week for production.

As you can see, i placed another order for more parts for my car. I wanted you to know that I'm pleased at how quickly the wheels/tires came, and the radiator too. Great service and response time.

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.
