The Vauxhall Cavalier Mk1 and Mk2 cover two distinct generations: the Mk1 ran from 1975 to 1981 as a rebadged Opel Ascona B and Manta B, and the Mk2 followed from 1981 to 1988 on the GM T platform. Both are now firmly in the historic and classic competition categories, and both see use in regularity rallies, historic sprints, and concours events. The floor geometry differs between Mk1 and Mk2 but the combined sub-frame listed here covers both platforms, which Corbeau have confirmed to their specification.
This sub-frame uses the floor fixing positions common to the Mk1 and Mk2 Cavalier, working from the original bolt points rather than drilling into floor steel that may be 40 to 50 years old. On a car of this age, preserving the structural integrity of the floor is a genuine concern during any seat installation. The kit may be a complete replacement frame or an adaptation bracket set depending on the specific configuration.
For base-mounted and reclining sport seats only. Side-mounted FIA race seats require separate hardware. Priced at £245 exc. VAT per seat position. Order twice for both sides. Note the Corbeau seat model in the checkout comments and we will confirm the fit before dispatch.
