Dinan Adjustable Front Sway Bar 32mm for E82 BMW 1M and E90 / E92 / E93 M3
Dinan E90 M3 sway bar is a chassis-tuned, adjustable 32mm front anti-roll bar for the E82 BMW 1M and the E90, E92, and E93 M3. Where the factory bars are sized for comfort, Dinan tunes the bar specifically to the chassis to cut body roll and keep the car flatter through a corner while still loading the tires for mechanical grip, for a more planted, confident feel on the road and track. The large, adjustable 32mm front bar sharply cuts understeer over the stock bar.
