What does the price include?

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.
What does this kit actually do?
It reduces the pulsing wind noise you get in the cabin when driving with the windows down, by disrupting the laminar airflow before it reaches the window gap.
Can I paint or wrap it to match my car?
Yes, it comes in a gloss carbon finish that Fabspeed says can be painted or vinyl wrapped to any colour.
How is it fitted?
With pre-applied 3M self-adhesive tape, for a simple DIY installation with no drilling or cutting. Either way works: fit it yourself, or have Rennen Motorsport or an authorised dealer do it for you.
Will it damage the paint if I remove it later?
Fabspeed says it can be removed cleanly at trade-in time or for Concours, thanks to the 3M adhesive tape used.
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?
