Carbon Fibre Rear Diffusers

for Road, Track and Racing

We manufacture a range of Carbon Fibre rear diffusers for universal fitment and Lotus, Caterham and Noble cars. We manufacture Carbon Fibre diffuser tunnels in various widths that can be joined together to form a rear diffuser with a 10° ramp angle which fixes along the front mounting edge that can be retained or cut to fit almost any vehicle.

Ideally, our diffusers should be mounted between 6° and 12° - we offer a range of adjustable stainless steel stays to allow mounting the rear of the diffuser and for fine tuning its angle.

Universal diffuser elements are 800mm long and available as 127mm, 270mm, 630mm or 790mm wide. We also offer separate diffuser vanes that can be bonded on to increase the number of elements on the diffuser. We produce a Group C style diffuser element that also allows for multiple elements to be bonded together that is 305mm wide and 1470mm  long.

We are able to customize our diffusers to suit your requirements, length and shape of vanes are available to any profile or depth, please specify when ordering or contact us for more information.

We also supply a range of accessories suitable for our diffusers allowing for convenient fitment to your vehicle and adjustment for optimum downforce. We have also built custom diffuser for individuals who require something different from our standard universal range, call or email to discuss your requirements.
