Dinan Sway Bar Set BMW M2/M3/M4 G80/G82/G87

OVERVIEW

Sharper turn-in, more mechanical grip, and a more planted, confident feel in every corner. Anti-roll bars are a car's main line of defense against body roll, but factory bars are tuned soft for comfort, not performance. Dinan's tuned Anti-Roll Bar Set replaces the factory sway bars with larger, more robust, tubular alloy-steel bars — built and calibrated specifically for the G8x chassis — reducing body roll while keeping just enough compliance for a confident, planted feel at the limit.

SPECS

• Larger, more robust bars: Front 28mm (vs. stock 23.5mm), Rear 26mm (vs. stock 21.9mm)
• Increased stiffness to combat roll: 18% stiffer front, 35–48% stiffer rear
• Less body roll, more mechanical grip, more stability at the limit
• Rear bar is 2-hole adjustable for fine-tuning stiffness to your environment or preference
• High tensile strength alloy steel, tubular (hollow) construction for maximum strength with minimal added weight
• Durable powder-coated blue finish for long-term wear resistance
• Legal for sale or use on Emissions Controlled, Non-Emissions Controlled, and Racing Use Only vehicles (does not affect emissions)
