Slotted Brake Rotor - Front Left (Hyundai Genesis)

StopTech Sport Rotors - the new name for one-piece performance upgrade rotors from StopTech. Formerly known as Power Slot or SportStop rotors, StopTech Sport Rotors are still the best aftermarket performance upgrade rotors around - only the name has changed.

If the rotors are the same, why the name change?
Simple - the new ‘StopTech Sport Rotors’ name more easily identifies their function, and more closely aligns them with the company’s other performance upgrade products. This includes the StopTech Sport Kits, which feature the StopTech Sport Rotors, along with StopTech braided stainless steel brake lines and StopTech Street Performance pads.

Will anything else change?
The part numbers will remain exactly the same, only the packaging, labels, catalogs and promotional materials will reflect the name change.

StopTech^® recognizes that great brakes need to look as good as they perform. Performance wheels and tires are best complemented with StopTech^® Slotted (prefix 126), Cross-Drilled (prefix 128) or Drilled+Slotted (prefix 127) Sport Rotors.

StopTech^® slotted, drilled and drilled+slotted brake rotors prevent glazing of the pads, add bite and improve wet and dry braking performance.

Every StopTech^® Sport Rotor is produced from a high quality Centric Parts^® blank casting and finished in a durable e-coating for corrosion resistance.

Engineered to look good behind the wheel and perform at the same time

StopTech® Sport Rotors look great behind custom wheels, improve the initial bite of the brake pads, and help wipe away the debris that forms between the pad and the disc. A set of StopTech^® rear replacement Sport Rotors is a great way to match the aesthetics of a StopTech® Big Brake Kit.

E-Coated Finish

Most StopTech^® Sport Rotors are finished with black e-coating on both sides of the hat, inside the cooling vanes, and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these area can lead to installed lateral run out issues.

Power Alloy Metallurgy

Power Alloy metallurgy is an exclusive feature of many StopTech^® rotors. In specific vehicle applications, StopTech works with foundry partners to increase the molybdenum or carbon content of the castings, and to carefully control the cooling rate during production to reach targets for hardness and tensile strength.

Cooling Vane Design

Nearly all StopTech^® 1-piece rotors have unique slot or hole patterns for the left and right sides of the vehicle. For these directional patterns, straight vane or pillar vane rotors are used to ensure that a drilled hole never touches a cooling vane.
