Ultra Racing 2-Point Rear Lower Bar – BMW 1 Series E87 130i

Improve rear chassis rigidity and handling consistency on your BMW 1 Series E87 130i with the Ultra Racing 2-Point Rear Lower Bar.

Designed to reinforce key mounting points underneath the chassis, this rear lower brace helps reduce unwanted chassis flex during hard cornering, braking and acceleration.

Ultra Racing part number:

URTW-RL2-3447

Improve Chassis Rigidity

During fast driving, the chassis is subjected to large forces as vehicle weight transfers from front to rear and side to side.

Hard cornering, braking and acceleration can place very different loads through each side of the chassis, which can allow the body and mounting points to flex.

Reducing this movement helps give the suspension a more stable platform to work from.

2-Point Rear Lower Brace

This Ultra Racing bar connects two structural points at the rear underside of the vehicle.

By reinforcing these areas, the brace is designed to help reduce unwanted movement between the mounting points and improve overall rear chassis rigidity.

Potential benefits include:

• Increased rear chassis stiffness
• Improved cornering stability
• More consistent suspension response
• Improved rear-end feedback
• Greater chassis confidence
• Reduced unwanted body flex

More Consistent Handling

Chassis flex can allow suspension mounting points to move slightly under load.

This can contribute to less consistent suspension geometry and changes in vehicle balance during demanding driving.

Increasing rigidity can help improve consistency during:

• Fast cornering
• Heavy braking
• Hard acceleration
• Rapid direction changes

Improved Suspension Response

Suspension components work most effectively when their mounting points remain stable.

Reducing chassis movement can help suspension inputs transfer more directly through the vehicle rather than being absorbed by unwanted body flex.

This can contribute to:

• More immediate chassis response
• More predictable handling
• Improved suspension feedback
• Greater confidence during performance driving

Helps Reduce Unwanted Handling Changes

Excessive chassis flex can contribute to changes in grip balance under load.

By helping reinforce the rear of the chassis, the Ultra Racing lower bar can support more predictable handling and reduce unwanted movement that may contribute to understeer or oversteer characteristics.

The overall balance of the car will still depend on tyres, suspension setup, geometry and driving conditions.

Ideal for Modified Cars

A chassis brace can be especially useful on cars that already have upgraded suspension or higher-grip tyres.

This rear lower bar can complement upgrades such as:

• Coilovers
• Lowering springs
• Uprated anti-roll bars
• Performance bushes
• Adjustable suspension arms
• Performance tyres
• Track-focused geometry

As suspension stiffness and available grip increase, chassis rigidity becomes increasingly important for maintaining consistent suspension behaviour.

Road & Track Use

The Ultra Racing 2-Point Rear Lower Bar is well suited to:

• Fast-road cars
• Trackday builds
• Performance-focused daily drivers
• Lowered vehicles
• Cars with upgraded suspension

It provides a straightforward chassis reinforcement upgrade without changing the fundamental suspension layout.

Vehicle Fitment

Exact fitment should still be confirmed before ordering, particularly where the vehicle has non-standard exhaust, underbody or suspension components.

If you're unsure whether this bar is correct for your BMW, please contact The Rosso Corsa Collective with your registration or exact model details.

Product Image Note

Product images may be generic or illustrative.

The exact shape, mounting arrangement and supplied hardware can vary depending on vehicle application.

If you need confirmation of the exact bar or mounting points before ordering, please contact The Rosso Corsa Collective.

Professional Installation Recommended

Professional installation is recommended.

All mounting points and fasteners should be checked during installation and tightened to the appropriate specification.

Ground clearance should also be checked, particularly on vehicles fitted with lowering springs or coilovers.
