Dinan Front Strut Tower Braces - BMW 430i / M440i (G22/G23/G26) 2021-2026

These braces tie the front strut towers into the chassis so the structure flexes less under cornering load, which shows up as steering that stays consistent as the car is loaded up instead of going vague at the limit. They are machined from solid billet aluminum and black anodized, and they replace the stamped and folded factory tubes that sit in the same place, which is the other reason people fit them. Installation is bolt-on with no drilling, and the design clears both the stock airbox and Dinan's own intake systems that retain the brace valley.
