Dinan Matte Carbon Fiber Strut Tower Brace - BMW M2/M3/M4 (G8x) 2021-2026

The Dinan Carbon Fiber Strut Tower Brace ties the front strut towers together to cut chassis flex under hard cornering, sharpening steering response and mid-corner stability. It replaces the OEM two-piece strut bar with a single blended structure molded from 2x2 twill carbon fiber with inset aluminum mounting points. At 2.8 lbs it saves 5.6 lbs over the 8.4 lb factory steel assembly, and it bolts on using the factory mounting hardware.
