I will find out when I call a contact. I have an associated question to ask him.
Many, including Myself, find the MB Silver Arrow setup to be very suited to hard driving. They are much cheaper than all alternatives, fit under 17" EVO 2s, and are nearly a bolt - on.
I have a 355mm setup similar to the Stoptech on one car. It gives even better brake FEEL, although the extra braking ability and resistance to heat up are really unusable on the streets or highways, and they don't fit under 17 inch wheels or possibly some 18 inch wheels.
