Professional grade, slotted rotors for greater braking performance. Smart slots and internal vanes keep these one-piece, high carbon iron rotors running cool. Be confident on highways and twisty roads with direct OEM replacements behind your wheels. Don't fall victim to the cross-drilled myth. These are a Kappasphere exclusive. Price is per set of 2 front rotors. Order all 4, save $50. Slotted, not drilled to Prevent Brake Fade - Slot edges continuously clean and refresh the pad surface.
- Maximized friction surface.
- Prevent containments from collecting between the pad and disc.
- Prevent water film on the disc in wet weather, maintaining the best brake response.
- Slotting allows hot gases to escape during hard braking.
- Helps keep the rotors cooler to prevent brake fade.
- Use with modern brake pad materials for more than adequate hot gas release.
- Porterfield R4-S Pads - Fronts
Why not cross-drilled? - Slotting keeps rotors cooler and lasting longer than cross-drilling.
- Proven on brake dynos around the world.
- Cross drilling compromises the structural integrity of the rotor
- Each hole is an opportunity for cracks to form.
Side Specific Internal Cooling Vanes - Cool both left and right sides (not just one).
- Right-side rotors spin clockwise; left-sides spin counter-clockwise.
- KSRdiscs' internal cooling vanes are optimally angled from left to right with those rotations in mind.
- Properly configured cooling vanes dissipate heat, and rotors run cooler.
- Many rotors don't take clockwise vs. counter-clockwise spin into account, neglecting one side!
- Cooler rotors are better performing and longer lasting.
