StopTech Sport Rotors are 1-piece, slotted direct replacement rotors for your factory brake system and stock calipers. 

StopTech Slotted Sport Rotors StopTech Sport Rotors are premium quality replacement brake rotors that feature a signature "short slot" design. The slot improves brake system performance by wiping away the debris of used friction material that otherwise accumulates between the rotor and pad. This keeps fresh pad material exposed to the rotor surface and helps prevent pad glazing. The edges sweeping the pad slightly increase the effective coefficient of friction or "bite," amplifying brake system response to pedal input. By providing an escape path for water, slotted rotors can also improve initial brake response under wet conditions.

Premium materials are the key to premium performance

 Power Alloy metallurgy is another unique feature of the StopTech Sport Rotors. Quality and performance live inside the rotor too.  Power Alloy iron specification is an enhancement in the carbon and molybdenum content of the iron. Carbon and molybdenum improves crack resistance and reduces noise, vibration and harshness (NVH).

Stoptech premium rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation (DTV). Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad-rotor break in. This special finish also provides quieter and smoother stops.
