Dinan Front Aluminum Strut Tower Brace - BMW G22/G23/G26 4 Series

Under hard cornering loads, the front strut towers on the BMW G22, G23, and G26 flex relative to each other — a subtle deflection that blurs steering feedback and reduces front-end confidence. The Dinan Front Aluminum Strut Tower Brace ties the two towers together, converting that flex into chassis rigidity and delivering more precise, immediate steering response without added weight.

Machined from aerospace-grade aluminum with a Dinan-finished surface treatment, it bolts directly to the factory strut tower mounting points with no drilling or permanent modification required. The result is a noticeably more connected front end, particularly when transitioning between corners.
