Dinan Anti-Roll Bar for 2006-2010 BMW M5 (E60)/M6 (E63) | D120-0491

The Dinan Rear Anti-Roll Bar (D120-0507) is a performance-engineered component designed to reduce understeer and significantly improve the mechanical grip and stability of various 2006-2013 BMW 1-Series and 3-Series models. Stock anti-roll bars are often designed to be overly soft for maximum comfort and to add understeer. This Dinan-tuned rear bar reduces body roll and keeps your BMW more level than stock, resulting in a much more planted and confident feeling in every corner.

The 15.8mm rear Anti-Roll Bar provides a substantial stiffness increase depending on the application. For the common 13mm bar found on many E9x models, the Dinan bar is 118% stiffer. For the E82 135i with an 11mm bar, the stiffness increase is up to 326%. This component may be added to the Stage 1 Suspension System for those building their high-performance suspension in stages.

Features:

• Substantial Stiffness Increase: Provides up to 118% stiffer than the stock 13mm rear bar and up to 326% stiffer than the stock 11mm bar (depending on application).

• Improved Dynamics: Significantly reduces understeer and body roll for sharper handling and a more stable feel at the limit.

• Enhanced Grip: Keeps the chassis more level than stock to dramatically improve mechanical grip.

• Precision Sizing: Large 15.8mm diameter ensures maximum performance from the rear axle.
