BMW G8X Anti-Roll Bar Kit Part Number: E40-20-057-01-11

Take control of your chassis with our newly released front and rear anti-roll bar kit, engineered specifically for the latest generation BMW M2, M3, and M4 (G8X platform).

Proudly manufactured at our Californian facility, this kit features lightweight tubular construction with 3-point adjustability on both the front and rear bars — giving you the flexibility to fine-tune handling balance to suit your driving style, road conditions, or track setup.

Development was no desk job. We partnered with a leading US race team to put the bars through their paces on track, refining the design through real-world testing and driver feedback. The result is a precisely tuned, performance-focused upgrade that excels in both spirited road driving and dedicated track use.

Key Features:

• Direct-fit application for BMW G8X chassis (M2, M3, M4)
• Tubular construction for an optimal strength-to-weight ratio
• 3-point adjustability, front and rear, for tailored handling balance
• Track-developed in collaboration with a US race team
