The Dinan adjustable front and rear sway bar set for the 21-27 BMW M3/M4 (G80/G82/G83) has 28mm & 26mm bars. Tuned for that chassis, it reduces body roll while still allowing just enough roll.

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.
