GD MK3R

A classic enhancement

The GDMk3R has a more purposeful aggressive stance over the standard GDMk3, its subtle wider arches allow the fitment of wider rubber taking advantage of the ever increasing power on tap from the modern V8.

 

The GDMk3R retains the same proven underpinnings of its siblings, 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


Developed 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 taut and responsive when pushed to the limit.




Body Shell - GRP Composite


Quite 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


The 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


Alloy 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


The GM Gen3/4 LS range of V8 engines have been installed in Gardner Douglas cars since 2001. We regard them as the best choice for power/weight with smooth drivability and offer better fuel economy, reliability and lower service costs. Today’s standard fitment is the 6.2Ltr LS3 or 7.0Ltr. LS7 and tuned variants.




Transmission - 5 or 6 speed H Gate


Tremec TKO 600 close ratio 5 speed or T56 and Magnum 6 speed




Differential - LSD 3.23:1 - 3.45:1


Speed sensitive limited slip differential provides awesome traction and neutral handling.




Brakes - Dual circuit with Bias


Brakes are dual circuit with ventilated discs as standard with AP racing 4 pot front calipers.




Wheels - 15" to 18" 3-piece


Wheels are offered in several sizes to suit preferred aesthetics and driving style. Typically 8.5×18 front and 10×18 rear. Optional classic peg drive.




High performance tyres - sizes vary


Example : Michilen pilot Supersport 245/40/18 F, 275/40/18 R tyres offer good all round performance. Optional track day compounds.




Steering - Rack and Pinion 2.4:1


An optional quick rack is available.




Fuel Tank - 50ltr stainless steel


Stainless steel construction. For safety the fuel tank is mounted between the rear axles. The upright design serves to minimise fuel surge.
