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 26.1mm), Rear - 19mm size (vs. stock 17.8mm)
  • Increased stiffness to combat roll; Front - 50% stiffer, Rear - 54-66% stiffer
