UMI Performance rear control arm kit for 2005–2010 Ford Mustang addresses flex in the S197 three-link rear by replacing factory components with a boxed upper arm and heavy-duty lower arms built from 1/8-inch wall steel tubing and MIG-welded fabrication. Assembled with greaseable polyurethane bushings and a durable powder coat, the bolt-in kit uses factory hardware. An optional spacer kit is available to reduce the factory 16mm mount hole to 14mm to limit suspension movement.
