034Motorsport Dynamic+ Sway Bar Kits - F2X/F3X

Transform your BMW F2X and F3X handling with a premium anti roll bar upgrade

Take control of body movement and sharpen your BMW’s responses with the 034Motorsport Dynamic+ anti roll system. Engineered for the F2X and F3X platforms, this front and rear ARB package delivers flatter cornering, quicker turn-in and adjustable chassis balance for both spirited road driving and track days.

Crafted from high grade spring steel and finished in a durable black powder coat, the bars are built to take punishment while maintaining precise roll stiffness. We run this kit on our own car and have installed it for many customers – the feedback is consistently outstanding for improved confidence and stability.
