What This Product Does

A seat shell kit is the structural and padded starting point for building a complete classic car seat. Instead of supplying a finished seat in a predetermined colour or material, the kit can be passed to a vehicle trimmer for covering in leather, vinyl, cloth or corduroy. This allows the upholstery, stitching, piping and other finishing details to be selected to suit the vehicle’s existing cabin or restoration specification.

The Spa-Francorchamps design follows the profile of purpose-built sports seats associated with the late 1960s and early 1970s. Its square-tube construction, formed side and back padding, separate cushion and headrest create a period-style bucket seat suitable for classic road cars and interior restoration projects. This version is intended for use with a suitable 3-point seat belt arrangement.

Functions

• Provides the supporting frame and shaped padding for an upholstered seat
• Allows the covering material and trim details to be specified separately
• Uses flexible Duralastic belts to support the padded seating areas
• Creates a period-inspired sports-seat shape with defined side support
• Includes a separate headrest for completing the seat assembly
• Supports installation with an appropriate 3-point belt system

Technical Details

• Square steel-tube frame construction
• Includes the seat frame and Duralastic suspension belts
• Supplied with formed side and back foam
• Seat cushion and headrest are included
• Fire-resistant foam is used within this type of seat kit
• Incorporates 360 mm Porsche 914 and standard 385 mm mounting patterns

Symptoms of Fault

• Original seat foam has compressed, hardened or become misshapen
• The cushion sags or provides uneven support
• Corrosion, fatigue or previous repairs have weakened the existing frame
• Suspension straps beneath the cushion have stretched or failed
• Seat movement or rattling indicates worn mounting components
• A complete foundation is required for an interior restoration

Why Replacement Matters

Beginning with a complete frame and foam kit gives the trimmer a consistent base on which to shape and tension the upholstery. It avoids applying new covers over deteriorated padding or a damaged structure and provides greater control over the finished appearance. Seat height, angle and adjustment will depend on the runners and vehicle-specific mounting hardware selected. Seat mounts, belt anchorages and belt routing are safety-critical, so installation should be completed or inspected by a suitably experienced specialist.
