Magic Pads are the new brake pad brand of choice for many professional racing teams in the USA. These custom designed compounds have proven themselves at the highest levels of racing and are now becoming available for club racing use. 

Magic Pad Compounds from Most to Least Aggressive. Descriptions are very generalized and as with all things on a race car applications are specific:

RP 41 - Heavy, high powered cars with lots of grip. Incredible initial bite and high friction. Advanced driver use only.

RP21 - Recommended for B46 and Spec E46 front pad. Can also be used as a rear pad when more friction is needed or for small rear brake system.

RP1H - Rear use only - lower friction and smooth bite and release characteristics for optimal trail braking and prevention of ice mode on stock ABS systems. As used on the rear of a B46 and Spec E46.
