Ultra Racing Front Lower Brace - 1 Series (F20)

Unlock sharper handling for your BMW with a front undercar chassis bar

Give your BMW 1 Series F20 a serious front-end upgrade with this Ultra Racing underbody reinforcement bar. By bracing the lower section of the front subframe, it cuts flex and keeps your suspension geometry stable under load, delivering crisper steering response, flatter cornering and a more planted feel on fast road drives and track days.

Why enthusiasts choose this front lower arm bar

• Increases front-end rigidity for confident turn-in and precise feedback
• Helps dial out push on corner entry for a more neutral balance
• More consistent braking stability and road-holding over bumps
• Flatter, more composed cornering with reduced chassis twist
• Enhances driver confidence and comfort on British B-roads

Construction and finish

• Manufactured from lightweight carbon steel for high strength-to-weight performance
• Signature solid white finish for durability and corrosion resistance
• Engineered to use factory mounting points for a clean, reversible install
