This notice is posted for all prospective customers who may involve in track racing to read, so they become a more knowledgeable and understandable in tracking their cars.
NOTICE FOR TRACK RACING
RB two-piece rotors are made from specially formulated alloys and high carbon cast ion, and are proven in the race tracks that they are highly resistant to wear, warping or thermal cracking under extreme heat cycles than OE or others.
Since our disc material is made harder (190-230 BHN) than stock, the same racing pads (compounds) you used to know or use that work on OE or competitions' rotors may not work well on our rotors. One of the most common issues is the pad deposit which is a substance emitted from the pad under high heat and transferred to the rotor surface that can cause vibration, pedal pulsation and hot spots on rotors surface resulting in thermal cracks and/or pre-mature brake failure.
It's individual racer's responsibility to ensure that a right pad compound is chosen can resist to the temperature he/she expects w/o emitting the deposit.
Understand that pad deposit comes from pad and stays on rotor, not originated or part of rotor. When it happened it can cause ill effect of braking performance which is beyond our control as a rotor manufacturer.

We have sold thousand sets of high performance rotors (one piece, two piece and brake kits), so far we received two complaints resulting from the pad deposit (build up):
First customer used RB one piece rotor for his front EVO and he used Ferrado 2500 pad:

Second customer used RB two piece rotor for his front STi and he used Carbotech XP10 pad:
http://forums.nasioc.com/forums/showthread.php?t=936395
Both cases were well discussed on their respective forums. However other customers with the same combination could produce satisfactory results.
Brake is a rather complicated system to optimize:

We also consulted a racing pads expert dealing with NASCAR racing teams, and his comments on brake pad deposit (build up):
Always check your pad suppliers, talk to your friends and make sure the pad you choose is appropriate for your braking temperature range and use (handle) them properly.
If you experience brake deposit, we recommend to clean it rather than resurfacing the rotor, although it may appear like rotor surface is grooved but actually it's metallic compounds emitted from the pad and it's removable. Per recommended procedures below.

We also consulted a racing pads expert dealing with NASCAR racing teams, and his comments on brake pad deposit (build up):
"There are several reasons that an unusual pad build up can occur on a rotor. It is important that the rotor be machined well with good parallelism, flatness, and run out. From our experience the RB rotors meet this standard and this should not be a concern. Some pad compounds are more prone to leaving build-up on rotors than the other. This especially occurs when the pad is used at temperatures outside the operating range the pad was designed for. It is important for racers to have an idea of what temperatures their brake systems are operating in at any given event and choose an appropriate pad for that temperature range."
