The Front Side Of The Rear Suspension Mount Is 2mm Narrower Between The Sus Pins Than The Standard Suspension Mount. Used In Combination With The Rear Suspension Mount (Rear Side/Z4-300LRR) And 1mm Long L5 Suspension Arm (Z4-008RS5), It Converts To A Long Suspension Arm Without Changing The Overall Width. Even When The Suspension Is Set Stiff On High-Grip Surfaces Such As Carpet Or Artificial Grass, It Induces Moderate Chassis Roll And Enhances Turning Performance Without Compromising Handling.

To Further Improve Front And Rear Balance, When Used In Combination With The 1mm Long Front Suspension Arm (Z4-008F1), It Delivers Even Higher Performance.
