Performance Shifter Cables
Numeric Racing's performance shifter cables for the 981 Boxster, Cayman, GT4, and Spyder, built with a wider cable diameter, aluminum rod ends, and stainless steel mounting connectors in place of the factory parts. The factory cables are known to eventually break, and Numeric Racing designed this set to eliminate the excess play that causes that failure, sharpening shift engagement in the process. It's a DIY install, though Numeric Racing recommends their 27mm bulkhead cable wrench to make the job easier, and the set is backed by their limited lifetime warranty. Some owners notice a bit more noise or vibration through the new metal cable ends, which the optional insulation tubing is designed to quiet down. It can also be fitted through Rennen Motorsport or an authorised dealer near you, for owners who'd rather not do it themselves.
Frequently asked
Which cars does the Performance Shifter Cables fit?
Fits your 981 Cayman. Fabspeed lists this piece for: Porsche 981 Boxster, Cayman, GT4, and Spyder (2012-2016). 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.
Will these cables eventually wear out and break like the factory ones?
Numeric Racing designed this set specifically to eliminate the excess cable movement that causes OEM cables to break, backed by their limited lifetime warranty.
Do I need any special tools to install these?
A 27mm bulkhead cable wrench is highly recommended, sold as an optional add-on if you don't already have one.
Will I notice more noise after installing these?
Some owners notice a slight increase in noise or vibration from the metal cable ends — Numeric's optional insulation tubing is designed to address that.
Which option should I choose?
The bulkhead cable wrench is a specialty 27mm tool for installation — worth adding if you don't already have one on hand. The cable insulation tubing is only worth adding if noise or vibration through the new metal cable ends bothers you; it's not required for the cables to function.
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.
