Rear Underbody Brace for BMW 1 Series E81 E87 2004 to 2011

Unlock tighter handling and a more connected drive with this rear lower chassis brace designed for the BMW E81 and E87 1 Series range. This undercarriage reinforcement links key mounting points at the back end of the vehicle to curb body flex, giving you crisper turn-in, improved stability through fast corners and a more confidence-inspiring feel on both fast-road and track-day setups.

Chosen by enthusiasts for its robust construction and precise fit, this upgrade is a proven way to sharpen steering response without increasing cabin harshness. Our workshop has fitted many of these units and customer feedback has been consistently positive, especially on spirited road cars and lightly tuned builds where extra rigidity transforms the chassis balance.

Why enthusiasts choose this rear chassis bar

• Reduces flex across the rear subframe area for a more planted, confidence-inspiring drive
• Sharper turn-in and more predictable mid-corner behaviour
• Enhances traction on bumpy roads and during hard acceleration
• Ideal foundation for suspension upgrades, performance tyres and alignment tweaks
• Purpose-built to suit OEM geometry for an accurate, repeatable fit

Compatibility
