Now you have additional brake options for your Speedway Engineering Hubs with the introduction of dynamically Mounted Rotor Adaptors to fit Wilwood and Performance Friction rotors.

Dynamically Mounted Rotors have better brake feel, run cooler, align with brake pads better and track truer with minimal distortion under maximum braking pressure.

Conventional brake rotors don’t run absolutely true. They all wiggle a little bit. No matter how careful you are any bearing looseness, rotor wear, manufacturing tolerances of the hub, rotor, and rotor adaptor (or brake hat) all add up. This can cause low brake pedal, less pad contact and in extreme cases can make your brake pedal pulse.

This is where dynamically mounted rotors come in. When you dynamically mount a brake rotor you allow a small amount of movement axially (side to side). When a brake rotor is spinning it can contain large amounts of stored energy. Under Newton's first law of motion he states that any body will continue in its state of motion (still or traveling) until outside forces change it. What this means is once the rotor is spinning it finds where it needs to be and stays there.

Now you can use dynamically mounted rotors on Speedway Engineering 2 inch bearing (howe/vogle), Wide 5, or Grand National hubs.
