Technical Description and Specifications

This disc brake rotor features a vented design that promotes airflow to dissipate heat effectively during braking. The drilled and slotted surface helps evacuate gases, dust, and water, maintaining consistent contact between the brake pad and rotor. With a nominal thickness of 22 mm and a discard thickness of 19.4 mm, the rotor ensures safe replacement intervals. The zinc silver hat finish and rust-resistant coating protect against corrosion, which is critical for maintaining rotor integrity over time. The rotor’s 5-lug bolt pattern with a 112 mm bolt circle diameter fits specific Chrysler and Mercedes-Benz models, including the C43 AMG, E55 AMG, and SLK55 AMG.

Compatible Vehicles and Applications
