Thank you. You have rated this product.

This high friction racing material has grown to be a very popular choice for drivers who need the highest possible friction with a low pad temperature. Developed and tested in the vintage racing community the R4-1 gives an average coefficient of friction of .56 with peak levels up to .600. Having tremendous stopping power, the R4-1 pad material can reach upwards of .5 friction level when pad temperature is a very low 200 F . 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. For use when pad temperatures are under 600 F and peak temperatures are not over 1000 F. Widely used on Vintage GT and formula cars the R4-1 has gained great popularity as an excellent auto-cross, off-road and rally-cross pad material. Great modulation, consistent pedal feedback and the same rotor friendliness as our other carbon kevlar compounds. .

BRIAN'S APPLICATION NOTES: This is the MOST aggressive pad you can actually leave on the car between events that has heat range to handle normal street use too....at least in warmer climates. For our RACING BRAKE RX8 big Brake Front kits with RB400 caliper (current caliper in the kit, pictured below...notice CENTER bridge bolt)>

Last week I spoke to Brian, I ordered a aluminum Koyo 37mm radiator for 97 Miata. Brian, you run a first class show! It arrived the next day. It is a fully polished work of art. The welding is perfect. The fit is perfect, old radiator slipped right out, new one slipped right in. Perfect. I am very pleased. Thank you.

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!)
