StopTech Power Slot 89-93 Mazda Miata SportStop Slotted Rear Left Rotor

When you're looking to get a little more out of your braking system on your 1990-1993 Mazda Miata, especially if you're driving it hard or just want a more responsive feel, a slotted rotor like this one from StopTech is a solid choice. It's designed as a direct replacement for your stock rear left rotor, making the swap straightforward. The main job of these slots is to help clear out heat, brake dust, and gases that build up between the pad and the rotor surface. This helps prevent the pads from glazing over, which can reduce their effectiveness, and it also gives you a more consistent and improved initial bite, whether you're braking in dry or wet conditions.

Beyond the slots, StopTech uses high-carbon metallurgy in these rotors, which is a step up from standard cast iron. This means they're built to handle the stress of repeated braking better, offering improved resistance to cracking from thermal stress. Plus, the black e-coating on the non-friction surfaces helps protect the rotor from rust and corrosion, keeping it looking good behind your wheels. This coating also works with the advanced metallurgy to help quiet down pad squeal, which is especially noticeable when paired with higher-friction brake pads.
