Schroth Profi II ASM 4 point Westfield harness. A professional 4 point harness, specifically configured for Westfield Sportscars. Recommended for use with competition type seats which normally have slots in the seat backs to allow free passage of the harness, although some high back, integrated headrest seats are not suitable for use with 4pt harnesses. These harnesses feature 3" shoulder straps with lightweight aluminium adjusters and anti-submarining (ASM) technology, with 2" pull down lap straps and Schroth's RFR race style rotary buckles, fixed to the inboard lap belt, with eye bolt snap hook type fasteners. The rotary buckle can be added to with a crutch strap to change them to a 5 or 6 point harness. Supplied with 4 eye bolts.
