Ultra Racing Rear Lower Brace – MINI F56
Improve rear chassis rigidity and handling consistency on your MINI F56 with the Ultra Racing Rear Lower Brace.
Designed to reinforce key structural points underneath the rear of the chassis, this brace helps reduce unwanted flex during hard cornering, braking and acceleration, giving the suspension a more stable platform to work from.
Ultra Racing part number:
URKR-RL2-3056
2-Point Rear Lower Brace
This Ultra Racing brace connects two structural mounting points across the rear underside of the vehicle.
By tying these areas together, the brace is designed to help reduce unwanted movement between the mounting points and increase rear chassis rigidity.
Potential benefits include:
- Increased rear chassis rigidity
- Improved cornering stability
- More consistent suspension response
- Better rear-end feedback
- Greater chassis confidence
- Reduced unwanted body flex
Reduce Chassis Flex
During performance driving, the chassis is subjected to significant loads as vehicle weight transfers around the car.
Fast cornering, hard braking and acceleration can place uneven forces through the body structure and suspension mounting points, allowing the chassis to flex.
Reducing this movement helps provide a more stable platform for the suspension to work from.
More Predictable Rear-End Behaviour
When the chassis flexes, suspension mounting points can move slightly relative to one another.
This can make the rear of the car feel less precise during harder driving.
By reinforcing the rear lower chassis, the Ultra Racing brace can help provide:
- More consistent rear-end response
- Improved stability through corners
- Better suspension feedback
- More predictable weight transfer
- Greater confidence during fast driving
Supports Suspension Performance
Suspension components work most effectively when their mounting points remain stable.
Reducing chassis flex can help springs, dampers, bushes and anti-roll bars work more consistently.
This makes the rear lower brace a useful supporting upgrade for MINI F56 models fitted with:
- Coilovers
- Lowering springs
- Uprated anti-roll bars
- Performance bushes
- Higher-grip tyres
- Track-focused geometry
- Other chassis bracing
Ideal for Modified MINIs
As suspension stiffness and available tyre grip increase, unwanted chassis flex can become more noticeable.
A rear lower brace can complement other handling upgrades by helping the rear suspension work from a more rigid and consistent structure.
Road & Track Use
The Ultra Racing Rear Lower Brace is suitable for:
- Fast-road MINIs
- Trackday builds
- Performance-focused daily drivers
- Lowered vehicles
- Cars with upgraded suspension
It provides additional chassis reinforcement without changing the fundamental suspension geometry.
Vehicle Fitment
Designed for:
- MINI Hatch F56
- MINI Mk3 / GEN 3

Exact engine, drivetrain and model compatibility should be confirmed before ordering, particularly where the vehicle has non-standard exhaust, underbody or suspension components.
If you're unsure whether URKR-RL2-3056 is suitable for your MINI, please contact The Rosso Corsa Collective with your registration or exact vehicle 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 brace 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 after installation, particularly on vehicles fitted with lowering springs or coilovers.
