Anti-roll bars are a common part of modern suspension systems whose job it is to do what the name implies – reduce body roll in all situations. However, from the factory, they are often designed to be overly soft for maximum comfort and not explicitly for improved driving dynamics.

Every Dinan tuned anti-roll bar on the other hand is built and tuned specifically for each targeted BMW chassis to provide a more responsive and crisp experience. By reducing the amount of body roll your BMW is kept much closer to 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 making it a must-have upgrade for back road and track enthusiasts alike.

Larger, more robust, bars; Front - 25mm size (vs. stock 23.1mm), Rear - 19mm size (vs. stock 18mm)

Increased stiffness to combat roll; Front - 56% stiffer, Rear - 54-66% stiffer

Rear bars are 2-hole adjustable allowing you to fine tune settings for environment or comfort preference
