StopTech Power Slot 07-09 Mazdaspeed 3 Slotted Left Rear Rotor

The black e-coating on this StopTech rotor isn't just for looks; it's a solid layer of corrosion protection that keeps the non-friction surfaces looking good and resisting rust. This rotor is a direct replacement for your factory brake disc, designed to work with your stock calipers. The high carbon metallurgy helps reduce noise and makes it more resistant to cracking under stress, which is especially helpful when you're pushing your Mazdaspeed 3 a bit harder.

You'll notice the difference from the slots machined into the rotor surface. These aren't just for show; they help clear out heat, brake dust, and gasses that can build up between the pad and rotor. This means more consistent braking performance, especially in wet conditions or during spirited driving, and it helps prevent the brake pads from glazing over. The double disk grinding ensures a flat, consistent friction surface right out of the box.
