WBR Run True Technology Metallurgic-Gray (MG) Finished Rotors All World Brake Resources (WBR) brake rotors with Run-True technology are manufactured to match the exact OE fit, OE construction, and precision finishing to ensure quick and easy installation, as well as trouble-free functionality for the life of the rotor. The Metallurgic-Gray coating is applied to all outward non-friction surfaces including in the gap between the plates covering the cooling vanes and cured through an oven drying process. The Gray coating provides an effective anti-rust protection to help maintain a clean appearance. The coating used for WBR is also similar to the OE color used by many OE car makes. WBR Brake Rotors with Run-True Technology have ultra tight tolerances that provide the finest braking experience, from break in throughout the life of the rotor, reducing the chance of warping even under extreme braking temperatures. The coated brake disc provides a protective water based coating that prevents rust and corrosion, extended rotor life and improved visual appearance. WBR Brake Rotors are manufactured to meet or exceed the original equipment manufacturer specification for durability, fit, and function.

Product Features:

• High metallurgical and machining standard to improve stopping distances
• Produced to match OE design fitment – G 3000 gray iron

Optimally engineered: ATE PremiumOne Disc Brake Rotors During heavy acceleration, a driver has to depend on bringing the vehicle to a safe stop in critical situations. Achieving maximum braking performance is guaranteed by the ATE PremiumOne Disc Brake Rotors. Its multifunctional infinite loop groove diverts gasses and dirt which could reduce braking performance. Fading is avoided and the life of the brake disc is extended. Water, dirt and the gases generated during braking can greatly reduce the braking performance of your vehicle. The ATE PremiumOne Disc’s continuous groove diverts these elements. The advantages are: better braking response and the cleaning effect of the continuous groove ensures score free, even wear which increases durability. Patented RotorLife wear indicator – Helps technicians and vehicle owners gauge rotor thickness at a glance, and notice when they are due for replacement. The wear indicator’s interlaced elliptical grooves are machined into the rotor face at complimentary angles. Groove design enhances dissipation of heat and gases to reduce brake fade, extend pad life, and looks great with cast spoke wheels. The MetaCote protective coating formulation is cured at approximately 572F. No grease or oil to remove. Helps protect against road salt, brake fluid and other corrosives – sheds water and dirt for clean appearance behind cast spoke wheels. Reduction in overall installation time. Application specific design is engineered to tighter tolerances than rotors that take a one size fits all approach. Fits and performs like or better than the original equipment it replaces – provides added value and convenience for brake technicians and their customers. No machining needed.

Product Features:

• Minimal fading. Maximum braking performance due to the revolutionary multifunctional groove
• Minimal scoring, even under high stress
• Longer service life
• Meta Cote anti-corrosion protection
• Safe braking on wet pavement
