• Disc type: Vented disc brake rotor with drilled and slotted surface
• Nominal thickness: 28 mm with discard thickness at 25 mm
• Overall height: 49.4 mm; outside diameter: 328 mm
• Rust resistant coating for extended durability
• Hat finish in Geospec silver grey for corrosion protection
• 5 bolt holes with a bolt circle diameter of 114.3 mm
• Directional brake surface optimized for heat and debris management

Detailed Product Features and Specifications

This disc brake rotor features a vented design that improves airflow to reduce heat buildup during braking, which is critical for maintaining consistent stopping power. The drilled and slotted surface helps evacuate gases, dust, and water, improving brake pad contact and reducing the risk of brake fade. The rotor’s nominal thickness is 28 mm, with a discard thickness of 25 mm, ensuring a long service life before replacement is necessary.

The hat of the rotor is finished in Geospec silver grey, providing additional corrosion resistance alongside the rust resistant coating applied to the entire rotor. With 5 bolt holes and a bolt circle diameter of 114.3 mm, this rotor is designed to fit securely on compatible Lexus and Toyota models. The directional surface pattern is engineered to optimize braking performance by channeling debris away from the pad surface.
