Inspired by a 60′s icon, the GDMk3 is an uncompromisingly modern sports car suited perfectly to a European landscape of narrow, winding roads and tracks where handling is pre-eminent over straight line speed, the latter comes easy!

Depending on final detail fitments the GD Mk3 can be every bit the classic sports car or take on a more contemporary appearance, whichever you prefer, It is the underpinnings that make the GDMk3 so indulgent and rewarding to drive!

The GDMk3 is available as a factory built car ready to drive away, or supplied in component form for self assembly. Prices are available to suit most budgets. All factory cars are built to order to individual customer preferences. For self build projects a full breakdown component pricelist is available on request.

Chassis - Tubular backbone

MK3 ChassisDeveloped for road and track use, the backbone design cloaks the power train and accurately locates the suspension for excellent power delivery with positive and precise control. Designed for huge V8 power the chassis always feel taught and responsive when pushed to the limit.

Body Shell - GRP Semi-Monocoque

MK3 BodyQuite unlike conventional body shells the GD body shell is a one-piece rigid semi-monocoque (tub) design with double skin mouldings. A composite construction made of glass fibre reinforced plastic with critical areas strengthened with advanced woven glass materials.

The tub rigidity is enhanced with front and rear bulkheads, engine bay, foot-wells, transmission tunnel and all inner mouldings as an integral part of the structure. Further occupancy protection is gained by injecting energy absorbing polyurethane foam into the body sides and the use of sliding anti-intrusion beams within the doors.

The body tub is insulated from the chassis with anti-vibration mounts adding further comfort and longevity.

Suspension - Double Wishbone

SuspensionThe chassis features independent double wishbone suspension with aircraft grade alloy uprights. Compared to conventional designs the suspension offers lighter unsprung weight and provides better camber control with adjustment for static camber, caster and toe-in settings. The suspension design gives the GD unrivalled levels of road holding and ride quality.

Spring Dampening - Adjustable Coil Over

DamperAlloy bodied shock absorbers are fitted with coil springs rated for intend use. The units are adjustable for damping resistance and ride height changes.

Engine - All alloy GM LS V8
