The Porterfield R4S is our favorite pad for performance street and autocross use. It does dust a little, but less than Hawk pads and its carbon kevlar construction is gentler on rotors.
DBA T2 Rotors utilize the proprietary Kangaroo Paw internal pillar design which provides superior cooling and more stable wear under high heat compared to conventional vane designs. All T2 rotors are slotted, not cross drilled! Why? Cross drilled rotors are notorious for cracking. We recommend slotted rotors, never cross drilled for ALL high performance uses and that is what we run ourselves.
Brian's MX5 Application Notes: this is a great aggressive use street and autocross brake setup...but look to our big brake kits for hardcore track work!
Brian's Miata Application Notes: this is a great aggressive use street and autocross MX5 Miata brake setup...but look to our SLOTTED only brake rotors or BIG brake kits for hardcore MX5 track work! Fits with stock calipers on all 06-13.
