GrimmSpeed 15-21 Subaru WRX/STI Strut Bar – Red

Bridging the gap between form and function, the GrimmSpeed Strut Bar is engineered to increase front-end chassis rigidity and improve driver feedback without unnecessary complexity. Instead of relying on standard sheet metal and welds, they opted for forged 6061 aluminum end brackets. These precision-machined forgings provide outstanding strength and a clean OEM+ appearance under the hood.

This bar features a hollow bent mild steel tube, powder coated in your choice of red or black. Each end is clamped via a dual-shear eyelet bolt design, chosen for its ability to maintain rigidity even in vehicles with slight chassis variance. Installation is straightforward, and no tuning or modifications are required. As with all GrimmSpeed products, they supply top-quality stainless-steel hardware to ensure lasting durability in the harshest engine bay conditions.
