Front engine, rear wheel drive.
Robust multi-tube 75mm x 50mm x 3mm box-section chassis with comprehensive round-tube triangulation and extensively braced / triangulated backbone section. Chassis includes separate triangulated scuttle-hoop section, structurally laminated into internal body tub and bolted across entire main chassis structure for maximum rigidity. All brackets included for engine, transmission, rear hoop/s, seats, seat belts, door hinges, differential unit, suspension arms & links, steering rack, etc.
Gel-coat finished GRP body, hand-laminated in high-heat distribution resin. All internal panels – passenger compartment tub, boot tub and front inner wheel arches – jig bonded into position, for easy and accurate body / chassis assembly. Double-skinned bonnet, boot and doors. (No GRP work required by the builder.)
Note – Body and chassis are designed to interlock with bonded and riveted faces to form an integrated immensely rigid (rattle & squeak free) structure.
Crumple zone design. Collapsible steering column (plus intermediate steering shaft offset with two UJs). Main chassis rails extend to full vehicle width for greater driver / passenger protection. Optional ‘Explosafe’ fuel tank.
