Front Splitter Ramps – Universal Aerodynamic Tyre Wake Control
Improve airflow, reduce turbulence, and increase front-end stability with Performance Delta Splitter Ramps.
Designed for universal motorsport applications, these aerodynamic ramps help control airflow around the front tyres — one of the largest sources of drag and instability on any performance vehicle.
Ideal for track cars, time attack builds, race cars, and high-performance road setups.
What Do Splitter Ramps Do?
Splitter ramps are mounted ahead of the front tyres and are used to:
Tyre wake is one of the most overlooked areas in vehicle aerodynamics — these ramps directly address it.
- Deflect high-pressure air away from the tyre face
- Reduce turbulent tyre wake (a major aerodynamic loss)
- Improve airflow along the vehicle side and underbody
- Increase effective front-end downforce and stability
Key Features:
- Designed to be mounted to a wide range of front splitters and aero setups. Suitable for custom builds and race applications.
- Internal vane splits and guides airflow progressively, maintaining flow attachment and reducing separation.
- Minimises turbulent airflow generated by rotating front wheels, improving downstream aero performance.
- Smooth transitions reduce drag and prevent pressure spikes at higher speeds.
- Manufactured from durable engineering polymer for excellent strength-to-weight ratio. Anneled post-manufacture to further enhance strength.
- Pick from 9mm, 12mm, 15mm and 15mm plywood thicknesses or message us for custom board config.
- Satin black surface with laser-etched Performance Delta branding.
Performance Benefits:
- Improved high-speed front-end stability
- Increased cornering confidence and turn-in precision
- Reduced drag caused by tyre turbulence
- Enhanced airflow into side skirts and underbody aero systems
Applications:
- Track day cars
- Time attack builds
- Club motorsport vehicles
- Race cars (circuit, sprint, hill climb)
- High-performance road cars with functional aero
Installation:
- Bonds or bolts directly to the top side of your front splitter surfaces
- Position typically aligned with front tyre leading edge or slightly outboard
- Can be adapted to suit a wide range of splitter designs
Dimensions:
- External (largest): 29cm wide, 25cm long, 6cm tall
Why Choose Performance Delta Splitter Ramps?
Most splitter ramps on the market are cosmetic. These are designed with one goal: functional aerodynamic performance.
If your build prioritises real performance over appearance, these ramps are engineered to deliver measurable gains.
