APR replaces the factory stamped aluminum brace with a high strength tubular chromium molybdenum alloy steel cross brace that ties both front strut towers to the firewall. The 25mm OD / 19mm ID tubing is TIG welded to billet end caps, finished in black powder coat and supplied with stainless steel hardware, while an integrated turnbuckle lets you set preload to suit the road or the track. Installation is a direct bolt-on with no cutting or permanent modification, and the design adds chassis rigidity under hard cornering and acceleration without introducing extra NVH.
