Up for sale is a set of DBA (42633S) Rear Slotted T3 4000 Survival Series Uni-Directional Rotors.

The 4000 T3 was built on the foundations of the T2, but the T3 slot design features additional precise CNC machined tri symmetrical slots, resulting in an even quieter, more responsive and smoother brake pedal feel. The T3 slot increases the number of exit points for brake pad friction dust and gases to escape through, further increasing the consistency and effectiveness of every brake stop. T3 rotors are denoted by the suffix (S) in 4000 Series part numbers.

Thermo-Graphic paint markings on the edge of DBA's 4000 Series rotors change color at specific temperature thresholds allowing you to check your braking performance quickly and easily. Green changes to white at 856°F, orange will change to yellow at 1022°F and the red will change to white after 1166°F. Ideal braking temperatures are between 850°F and 1000°F (so the green will become white and the orange and red are unchanged).
