Transform the way your BMW corners with this Dinan 21 mm adjustable rear sway bar. Purpose-built for the E60 M5 and E63 E64 M6, this rear stabiliser upgrade dials out excessive roll, sharpens turn-in and boosts rear-end composure for confident fast-road driving and track days.

The result is a flatter chassis through bends, improved mechanical grip and a more balanced, planted feel without sacrificing everyday usability.
