GT500 Mustang Front Lower Control Arms

(No reviews yet) Write a Review
The SPL Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for the Shelby GT500 and 2020 GT350. 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 arms.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.

GT, EcoBoost, V6) Front Lower Control Arms Install Instructions SPL FLCA GT500 Instructions IMPORTANT INSTALL INFO S550 KNUCKLE TAPER VARIATIONS Ford made numerous variations of the front knuckles across the S550 Mustang and Shelby line-up. These knuckles vary across nameplates (Mach 1, GT350, etc), years (2019 vs 2020 GT350), and even options (Handling Pack 2, etc). Each knuckle variant may have different conical tapered seats where the front control arms mount. It is VERY IMPORTANT to verify the supplied conical tapered spacer fits snuggly into the knuckle, has near zero lateral end play (as-in it will not rock within the bore), and seats fully into the knuckle when installed at the proper torque value. If you need clarification or feel you may have the wrong spacer for your Mustang, then please email us.
