Product Description

The BMR Rear Lower Control Arms (LCA570) are purpose-built for 2014–2019 Chevrolet Corvette C7 owners converting to a 15-inch rear wheel setup for drag racing. Engineered to provide the necessary wheel clearance while dramatically increasing suspension rigidity, these heavy-duty control arms eliminate the flex and bushing deflection associated with the factory stamped steel arms. The result is improved traction, reduced wheel hop, and more consistent launches when every tenth of a second matters.

Constructed from 1.25-inch DOM steel tubing, the LCA570 features a hybrid design that combines 85-durometer polyurethane bushings with heavy-duty Teflon-lined chromoly rod ends. This provides the ideal balance between articulation, strength, and street drivability while maintaining precise suspension geometry under extreme loads. Whether you're building a dedicated drag car or a high-horsepower street Corvette, these control arms deliver the durability and performance needed to put power to the pavement.

Why Upgrade?

The factory rear lower control arms weren't designed to accommodate a 15-inch drag wheel setup or the extreme loads generated by high-horsepower launches. The BMR LCA570 solves both problems by providing the clearance necessary for drag wheels while dramatically reducing suspension flex and wheel hop. Whether you're chasing a new personal best at the drag strip or building a 1,000+ horsepower C7, these control arms are a critical component for maximizing traction and repeatability.
