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.
Add a 19mm Lightweight Tubular Adjustable Rear Anti-Roll Bar to reduce body roll to improve grip and stability while saving weight at the same time. This anti-roll bar is adjustable up to 359% to 474% stiffer than the stock bar*. This 3 hole bar can be mounted in 3 different positions with stock BMW end links.
Add a 25mm Lightweight Tubular Adjustable Front Anti-Roll Bar to reduce body roll to improve grip and stability while saving weight at the same time. This anti-roll bar is adjustable up to 45% to 93% stiffer than the stock bar*. This 3 hole bar can be mounted in 3 different positions with stock BMW end links.
The stock bar is 22.5 mm on the 228i/230i/320i/328i/330i/428i/430i which means the new bar can be adjusted from 61% to 93% stiffer than the stock front sway bar.
