Carbon Fiber OEM-Style Rear Diffuser Fins
Carbon fiber rear diffuser fins for the Ferrari 458 Italia and Spider - six fins only, designed to attach to the existing rear diffuser panel rather than replace the whole diffuser. They install as a direct replacement over either the factory fiberglass or carbon diffuser, so you don't need to swap the diffuser itself to fit them. No core exchange is required, so your original fins stay with you.
Frequently asked
Does the Carbon Fiber OEM-Style Rear Diffuser Fins fit my 458 Italia?
This listing is specific to the Ferrari 458 Italia. 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.
Do I get the whole diffuser or just the fins?
Just the six fins that attach to the existing rear diffuser panel, not a full diffuser replacement.
Will these fit if I already have a carbon aftermarket diffuser?
Yes, Fabspeed says they install as a direct replacement over either the factory fiberglass diffuser or a carbon diffuser.
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.
