Under heavy cornering or hard launches, the factory control arm link deflects and flexes due to the weak stamped steel design. BMR designed these 2015-2019 Mustang vertical control arm links to eliminate that. These links are constructed from high strength steel to eliminate flex as well as transfer power to the tires better. These vertical links come upgraded with polyurethane bushings to help give you an enhanced feel of the road and will last much longer than the factory rubber bushings. These vertical links are constructed to withstand extreme race conditions time after time. Polished with a fine red coating to ensure a clear finish that withstands any condition.
