    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.

    Installation Instructions
    • Made of high tensile strength alloy steel with tubular (hollow) construction for maximum strength while limiting weight
    • Rear bars are 2-hole adjustable allowing you to fine tune settings for environment or comfort preference
    • Larger, more robust, bars; Front - 28mm size (vs. stock 23.5mm), Rear - 26mm size (vs. stock 21.9mm)
    • Increased stiffness to combat roll; Front - 18% stiffer, Rear - 35-48% stiffer
    • Includes polyurethane bushings and grease
    • More stable at the limit
    • More mechanical grip
    • Less body roll
