Dinan Lightweight Tubular Anti-Roll Bar Set – BMW M2 / M3 / M4 (F8x)

OVERVIEW

Nearly every modern street car leaves the factory with anti-roll bars, but they are tuned soft in the interest of ride comfort. Dinan builds and tunes each of its anti-roll bars specifically for the BMW chassis it is fitted to, cutting body roll so the car stays flatter through a corner while still allowing just enough roll to load the tires — for more mechanical grip and a more planted, confident feel at the limit.

The 32mm tubular front bar is adjustable from 57% to 103% stiffer than the stock 24.7mm bar across seven mounting positions, while the 24mm tubular rear bar is adjustable from 0% to 13% stiffer than the stock 22.9mm bar across three positions using the factory end links. Both bars use hollow tubular construction, delivering the larger diameter and higher rate without the weight penalty of a solid bar.
