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 suspension upgrade is 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 the Front Roll Control System to improve grip and stability by reducing body roll. This system moves the mounting points of the stock anti-roll bar so that it acts like a stiffer bar thus reducing body roll.
Designed for use with 21mm Adjustable Rear Anti-Roll Bar for proper balance for cars with less than 30mm difference between the front and rear tire width. This Front Roll Control System and the 21mm Adjustable Anti-Roll Bar may be added to the Stage 1 Suspension System for those who wish to build their high-performance suspension in phases.
