You are looking at the FactionFab Swept Slot Bi-Directional Rotor. This rotor is ideal for street use and for the occasional spirited drive and will improve your overall braking response, brake cooling and thermal stability, pad cleanliness, and overall increased braking performance in any situation.
Shallow Sharp-edged groves are milled into a high carbon cast iron disc to provide consistent pad contact and maximum friction over repetitive use.
High-Carbon content for wear resistance, thermal stability, and cracking resistance
Bi-directional design, meaning rotors are not side specific
Symmetric vane castings to increase heat dissipation efficiency and thermal stability
Double-disc ground, non-directional finish
Mill balanced for reduced vibration
Precision machined with Run-out spec of no more then .002", Disc Thickness Variation (DTV) of .0005"
Fully machined non-friction surfaces for perfect fitment
Electronically applied E-Coating for corrosion resistance
400-hour salt spray tested
Fully coated inside and out
