Dinan Lightweight Tubular Anti-Roll Bar – BMW 1M / M3 (E82/E90/E92/E93)

OVERVIEW

Almost all street cars leave the factory with anti-roll bars, but they are tuned soft for maximum comfort. An anti-roll bar reduces body roll, and every Dinan bar is built and tuned for a specific BMW chassis. Keeping the car flatter than stock — while still allowing just enough roll — improves mechanical grip and gives the driver a far more planted, confident feeling in every corner.

This Lightweight Tubular Adjustable Front Anti-Roll Bar reduces body roll and saves weight at the same time: it is 42% lighter than a solid bar of comparable stiffness and adjusts from 50% to 90% stiffer than the stock bar. The three-hole bar can be mounted in five different positions, and the supplied end links use left- and right-hand threads for easy length adjustment. It may be added to the Dinan Stage 1 Suspension System for owners building a high-performance suspension in phases.
