Baer Eradispeed Rotors are offered in Eradispeed & Eradispeed Plus Versions. The standard Eradispeed Rotors are a direct replacement performance rotors are all cast with an integral hat or hub/hat section just like the original OEM rotor. Each one, however, is a unique casting which employs either a directional curved vane or the patented Kangaroo™ port design. All benefit from additional mass in the “firepath,” as well as a proprietary, high-friction iron formulation. Each EradiSpeed™ unit is also crossdrilled, slotted and then zinc washed for rust resistance.

EradiSpeed+ versions are still direct OEM replacement units, but the “plus” indicates rotors which are of a two-piece design. The center “hat”, or “hub/hat” portion of EradiSpeed+ rotors are CNC machined from billet or forged aluminum. The centers are then anodized black to finish the “look” and are bolted to the rotors with National Aerospace Standard (NAS) stainless, reusable fasteners, the same hardware used to affix the rotors to an Indy Car. With their two-piece design, EradiSpeed+ units also provide a welcome reduction in total rotor weight.

For certain applications, Baer additionally offers Eradispeed + 1 Rotors. These rotors are of a size larger than the original, which will still work with original calipers. This results in increased performance (brake torque) by virtue of the increased leverage of the larger diameter rotor. Slight modifications are required for these larger rotors.

For “ES+1” applications, Baer provides all the hardware required to move the location of the stock factory caliper outward. In some cases an intermediate bracket is employed, in others new factory style caliper anchor plates are provided. In all cases, except as noted, +1 upgrades install without bleeding the brakes and many, such as the ES+1 for the rear of the C5, also fit the OE wheels.
