Ford Focus ST(2013-2018) Rear Strut Bar (Booty Boot Camp)By bracing the spring perches and shock mounts, rear traction and grip will be dramatically increased! Bolt on the competitive edge you need with this lightweight rear strut bar! Dont trust competitors that only brace the top of the shocks. This simply leaves way too much performance on the table. This brace connects both the spring perches and the shock mounts for a fully integrated strut bar! Stiffen up the rear suspension immensely! Hand Mig Welded
