Willans MX-5 6-point Road and FIA Harness NEW: FIA approved to FIA 8853-2016 for Road and Competition Use. This NEW harness has been specifically developed for these MX-5 cars. It features brand new patented aluminium lap adjusters that clip directly into the composite Rotary Buckle. This enables the maximum adjustment of the length of the lap straps and ensures they can be tightened fully with absolute ease. This has solved the issue that some MX-5 owners traditionally have with normal harness adjusters that can be harder to adjust in some circumstances. Willians Aluminium Adjusters to the Shoulder Straps are also a standard feature on this top of the range MX-5 harness.
These MX-5 harnesses have shorter shoulder straps designed to wrap around a roll bar or harness bar, they are ideal for use in your MX-5 if used on the road, for FIA events, or just for track days.
As standard they feature shoulder straps manufactured to the correct length ready to wrap around your roll bar or harness bar, the NEW lap straps are tensioned by pulling downwards away from the central buckle. Lap straps have Snap Hook fixings and eyebolts are supplied that fix to the original seatbelt mounting points in the car.
A harness bar manufactured specifically for the MX-5 can be supplied if required. Please use dropdowns to order.
Patented lightweight composite Rotary Buckle finished in satin black with a black Willans badge as standard; the badge (not the buckle) can be upgraded to Signature Red or Blue.
The Rotary Buckle is permanently fixed to the crutch strap. Shoulder Straps are all 3 inch (75mm) wide. Lap straps have the option of 2 inch (50mm) (recommended) or 3 inch (75mm), Crutch straps are 2 inch (50mm). Signature range includes additional colours and the option of the Historic Willans Label if required. Stitching thread is self-colour (same as harness colour) unless upgraded to a Signature colour using the dropdowns on the page. Shoulder pads are available in Black, Blue or Red only with Modern or Historic Labels. All straps are fully adjustable. Superb Willans quality throughout. Manufactured in the UK. A free Safety Hammer is included with every order.
