Ford Mustang S550 15-23 Front Lower Control Arms

The SPL Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for S550 Mustangs. Using a mixture of billet aluminum, stainless steel, chro-moly steel, and titanium results in strong, adjustable arms that are 2.0 lbs lighter than stock Performance Pack arms. Non Performance Pack Mustangs will also benefit from eliminating bushing deflection, resulting in sharpened steering response and driving precision.

The ability to run more negative camber greatly improves the peak lateral grip available, dropping several seconds off of lap times when tested on the Vorshlag Dark Horse. This is especially important with better tires and a must-have for anyone looking to prevent excessive outer shoulder wear (and heating) on their tires due to a lack of camber.

The lower control arms come with a ride height sensor bracket to maintain factory ride height sensor location, regardless of length of the arm to keep the Ford chassis electronics happy.
