Zimmerman cross-drilled rotors do a better job of dissipating heat and gasses from your brakes than standard rotors under extreme braking. Zimmerman cross-drilled rotors have carefully machined holes strategically placed across their surface. The holes in Zimmerman cross-drilled rotors allow air to flow through the actual surface of the brake disc, resulting in huge improvements in cooling and a resulting reduction in brake fade. Zimmerman cross drilled rotors also allow dust and gasses that build up on the rotor surface to escape into the atmosphere rather than affect brake operation. The cumulative result is that Zimmerman cross-drilled rotors run cooler, stop better, reduce fade, and dissipate dust more effectively. Behind the obvious advantages of Zimmerman cross-drilled rotors lie sound basics, like heat-treated steels and precise machining.
Please note: Like all race parts there is no warranty on these rotors except for obvious manufacturing defects. Sold as each.
