The Luke Westfield Pro 4 Point Harness in 50mm/50mm is the narrower-webbing version of the Westfield-specific Pro range. Snap-on shoulder connections, bolt-on lap straps, and the rotary-action release box that opens with a single turn. Cut for the Westfield Sports Cars chassis. Road legal, MOT compliant. Not FIA homologated.
50mm webbing is lighter than the 75mm version and costs less: WPRO4 at £129 versus the 75mm (LUKJGJ2K470 at £157.50). The 50mm is the practical choice for a Westfield that is primarily road registered and occasionally tracked, where saving weight and keeping cost down both matter. The 75mm is worth the extra for drivers who run the car on track regularly or under hard sustained braking.
Fully adjustable on both lap and shoulder straps. Pull Down or Pull Up adjustment available. Black, Blue, Red, Silver and Purple. Supplied with an easy-fit snap hook system and eye bolts, so the mounting hardware is included. Luke straight-stitch construction in Sussex, red release handle for emergency crew recognition, serial code trace on each harness.
If your car is a Caterham, the CPRO4 is the equivalent in Caterham-specific dimensions at £132.50. The two cars use different bolt point positions and cockpit geometries, so they are not interchangeable. We carry the Westfield Pro range in both strap widths. Ask us if you need lead time confirmed before ordering.
