Dinan 21-26 BMW 430i/M440i xDrive (G22/G23/G26) Adjustable Front & Rear Sway Bar Set - 25mm & 19mm

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. Front: 25mm - Rear: 19mm - Adjustable - G20/G22/G23/G26/G42 Dropping of the subframe is required so professional installation is highly recommended.

Constructed from high-tensile-strength alloy steel with a tubular, hollow design, these Dinan sway bars deliver increased stiffness without unnecessary weight. Compared with stock bars, the front bar is 56% stiffer and the rear bar provides approximately 54% to 66% greater stiffness, depending on adjustment position. The rear bar features two adjustment holes so drivers can fine-tune handling balance for driving conditions, track use, or personal comfort preferences. Polyurethane bushings and grease are included for a complete installation.
