Large Single Vane Splitter Ramp / Diffuser / Tunnel

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:

• 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

Tyre wake is one of the most overlooked areas in vehicle aerodynamics — these ramps directly address it.

Key Features

Universal Motorsport Fitment

Designed to be mounted to a wide range of front splitters and aero setups. Suitable for custom builds and race applications.

Aerodynamic Multi-Vane Design

Internal vane splits and guides airflow progressively, maintaining flow attachment and reducing separation.

Tyre Wake Reduction

Minimises turbulent airflow generated by rotating front wheels, improving downstream aero performance.

Optimised Ramp Geometry

Smooth transitions reduce drag and prevent pressure spikes at higher speeds.

Lightweight, High-Strength Construction

Manufactured from durable engineering polymer for excellent strength-to-weight ratio.  Anneled post-manufacture to further enhance strength. 

Designed to universally suit phenolic plywood thickness

Pick from 9mm, 12mm, 15mm and 15mm plywood thicknesses or message us for custom board config.

OEM+ Motorsport Finish

Satin black surface with laser-etched Performance Delta branding.

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.
