Detailed Product Description

This Power Stop rotor is specifically designed for front axle use on Volvo S40 and V40 vehicles. The high carbon cast iron construction improves thermal conductivity and reduces the risk of warping under heavy braking conditions. The Geomet coating provides a protective layer that resists rust and corrosion, extending the rotor's service life. Its vented design enhances airflow, helping to maintain optimal operating temperatures and reduce brake fade during extended use.

The rotor's precise dimensions, including a nominal thickness of 0.94 inches and an outside diameter of 11.10 inches, ensure proper fitment and compatibility with the specified Volvo models. The mounting bolt hole circle diameter of 4.50 inches and four lug holes align with factory specifications for secure installation.
