Almost all street cars come from the manufacturer with an anti-roll bar as it is a common part of modern suspension systems. However, they are designed to be overly soft for maximum comfort. An anti-roll bar does exactly what it says by reducing body roll in all situations. Every Dinan tuned anti-roll bar is built and tuned specifically for each BMW chassis. Lowering the amount of body roll keeps your BMW more level than stock (while still allowing just enough body roll) to improve mechanical grip. This improvement gives the driver a much more planted and confident feeling in every corner.
Front Anti-Roll Bar
Add a 28mm Lightweight Tubular Adjustable Front Anti-Roll Bar to reduce body roll to improve grip and stability while saving weight at the same time. The Lightweight Tubular Adjustable Front Anti-Roll Bar is 44% lighter than a solid anti-roll bar of comparable stiffness. This anti-roll bar is adjustable from 35% to 53% stiffer than the stock bar. This 2 hole bar can be mounted in 3 different positions with supplied end links that are left and right hand threaded for easy length adjustment.
Rear Anti-Roll Bar
Add a 22mm Lightweight Tubular Adjustable Rear Anti-Roll Bar to reduce body roll to improve grip and stability while saving weight at the same time. The Lightweight Tubular Adjustable Rear Anti-Roll Bar is 29% lighter than a solid anti-roll bar of comparable stiffness. This anti-roll bar is adjustable from 39% to 72% stiffer than the stock bar. This 3 hole bar can be mounted in 3 different positions with stock BMW end links.
