Dinan 21mm Adjustable Rear Anti-Roll Bar for M5 E60 M6 E63 M6 E64
Add 21mm Adjustable Rear Anti-Roll Bar to improve grip and stability by reducing body roll. Adjustable with 3 positions on the bar for easy adjustment.
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.
This 21mm Adjustable Rear Anti-Roll Bar may be added to the Stage 1 Suspension System for those who wish to build their high performance suspension in phases.
+ Less Body Roll

HIGHLY RECOMMENDED: Designed for use with Front Roll Control System for proper balance for cars with less than 30mm difference between the front and rear tire width.
What is the difference between an anti-roll bar and a sway bar?
Nothing. It is common for enthusiasts to drop the "anti" when talking about roll or sway bars.
Doesn't a stiffer bar limit more body roll?
Yes, however this can be taken too far. A bar that is too stiff will limit body roll too much so that not enough weight is transferred to the outside wheels to add to mechanical traction. Beware of the overly stiff anti-roll bars sold in the aftermarket.
