Raybestos ST-43 are a favourite intermediate track pad. Very aggressive pad, yet easy on the rotors. They are down slightly on overall friction and initial bite from the most aggressive offerings, with the flipside being lower running temps and increased component life.
We have customers running them in Ferrari Challenge cars, Evo's, STi's, Vipers, Corvettes and more. If you rely on ABS, these pads will be more forgiving with their initial bite. When you read the factory literature for these pads, they downplay them a bit as being not very aggressive. Developed for Nascar, so heavy, high-horsepower, lots of tyre and downforce.
