Mazda, apparantly 🙂
“The world of high performance brake pads has changed many times in the last few years. The first major factor was the banning of all asbestos in any brake material. The next was the introduction of carbon/metallic and carbon/kevlar material. There were initially many different combinations of compounds, virtually none of which were available for any MAZDA. This has finally all settled down, and we are now able to offer carbon/kevlar pads for all the MAZDA’s that work great for hard street driving, autocross/slalom, and road racing. The carbon/kevlar we offer is much less destructive to the rotors as compared to the carbon/metallic. They also require much less “bedding-in”, work fine when cool, warm up fast, and last the same as the carbon/metallic.”
