LW Steel Rotor .810in. x 12in.

The LW Steel Rotor .810in. x 12in. from Diversified Machine is a lightweight, slotted brake rotor engineered for performance-focused automotive builds where weight reduction and thermal management are priorities. Designed for street and track applications, this rotor reduces unsprung mass while maintaining the structural integrity required for reliable braking. It's ideal for enthusiasts upgrading domestic muscle cars, hot rods, or any project vehicle where cutting rotational weight translates directly to improved acceleration, handling response, and fuel efficiency.

This rotor features a 12.000-inch outer diameter with a 0.810-inch thickness and mounts via an 8 x 7.000-inch bolt pattern, making it compatible with most domestic brake applications. The slotted design enhances pad bite and gas evacuation, helping to scrub brake dust and improve thermal dissipation under repeated hard stops—critical when running higher-performance pad compounds. Manufactured from iron in a natural finish, the lightened construction reduces rotating mass by approximately 5.93 lbs compared to OEM equivalents, lowering the mechanical load on wheel bearings and suspension components while maintaining proven iron durability over carbon alternatives.

Mechanics and performance builders commonly specify the LW Steel Rotor for front or rear axle upgrades on Chevy, Ford, and Mopar platforms, as well as generic applications requiring a 12-inch rotor with that specific bolt spacing. Installation requires standard brake service tools and familiarity with rotor removal and pad change procedures. Pair these rotors with high-friction brake pads and quality brake fluid for optimal stopping power and fade resistance, especially on vehicles running larger engines or frequenting the track.
