Frequently asked
Does the Harness Bar & Mounting Kit fit my MP4-12C?
This listing is specific to the McLaren MP4-12C. 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?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
Does this include the harnesses themselves?
No, harnesses are sold separately; this kit is the mounting bar and hardware only.
Will it fit an MP4-12C Spider?
No, this kit is coupe-only.
Can I get a custom colour?
Yes — tell us your preferred colour when you order and we'll arrange custom paint in addition to the standard powder-coated gloss black.
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.
