This is a new old stock, still in the box,  set of Alcon Raybestos 4 piston, billet aluminum narrow speedway solid bridge, radial mount differential, 38mm / 42mm titanium 4 piston for 328mm x 28-32mm rotors w/
a 15" wheel or larger. Part #PC1000 R&L. Pad shape is Raybestos #R2002, PFC  #7700 & #7718. One new set of pads is included. These fit the same mounts and rotors as the Brembo Speedway clip bridge
models but are smaller in size and stiffer with better performance . Because of their compact size, these are super stoppers on lighter cars and imports. Great Drift Car Brakes! LAST SET
