EBC RK860 Ultimax Slotted Rear Brake Rotors for 1998-2003 BMW 525i, 528i and 540i

Upgrade the braking performance of your compatible BMW with the EBC RK860 Ultimax Slotted Rear Brake Rotor Set. Designed as an OE-style disc kit, these vented rotors use progressively angled slots to improve brake cooling while avoiding the excessive air noise often associated with aggressively slotted designs. The result is quiet, consistent operation for daily driving and spirited road use.
The angled slots help draw cool air across the braking surface, supporting more stable brake performance under repeated braking. They also help clear excess brake dust, debris, and gases from between the pad and rotor, helping maintain strong pad contact and consistent grip. By reducing surface contamination and managing heat, the Ultimax design may also support longer pad service life when paired with properly matched brake pads.
This EBC Ultimax rotor set is engineered for the rear axle and is compatible with applications using FMSI pad number D1239. Each rotor features a vented construction, five bolt holes, a 75-millimeter center hole, and a 20-millimeter braking surface thickness. The 298-millimeter rotor diameter and 61-millimeter height support the original equipment fitment requirements without listing overall product dimensions. Verify vehicle configuration and brake system details before installation.
