Carbon Fiber Rear Diffuser Assembly
A carbon fibre rear diffuser assembly for the Porsche 981 Boxster and Cayman, built to OEM fitment. It installs in the factory location with no modification needed, and is supplied as a replacement part rather than a core exchange, so the original diffuser stays with the car.
Frequently asked
Which cars does the Carbon Fiber Rear Diffuser Assembly fit?
Fits your 981 Cayman. Fabspeed lists this piece for: Porsche 981 Boxster/Cayman. Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Carbon pieces are made to order at Fabspeed USA, and the standard one-week lead time doesn't apply: the lay-up and curing process means build times vary a lot with part complexity. That's exactly why these are consult-only — we confirm the current build time with Fabspeed and give you a real date on your free consult before anything is ordered. Delivery to Australia then adds 3-4 days via UPS, included in the price.
Does fitting it require any modification?
No, it's built to OEM fitment and installs in the factory location without modification.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
