Chassis - Tubular spaceframe
A comprehensive braced space frame fabricated from steel tube. The design offers great rigidity and strength as you might expect, but also offers high levels of occupant protection. Front and rear crash frames solid bulkheads, triangulated double skinned side pontoons and full roll-over bar cross-braced to meet race regulations.
Designed for high output V8 power, the chassis always feels taught and responsive when pushed to the limit.
On a practical point, the chassis pontoons provide ample stowage for soft luggage.
Body Shell - GRP Composite
The body panels are moulded in composite. Front and rear panels can be easily removed for access to mechanical components. The optional windscreen offers pleasant road comfort at speed while being detachable if preferred for track use.
Options include moulded exterior colour saving the need for paint, rear canopy vents, venturi and front spoiler.
Suspension - Double Wishbone
Purpose designed independent double wishbone with aircraft grade alloy uprights. Rocker arm mounted damping offers long wheel travel while maintaining excellent camber control. Carefully selected spring rates gives the GD T70 exceptional levels of mechanical grip while maintaining a surprising high standard of ride. Damping is adjustable for bump and rebound resistance and ride height changes.
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 EFI V8
The GM 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 driveability and better fuel economy, reliability and lower service costs than earlier types.
Typically we offer four normally aspirated options:
Stock GM Gen. IV LS3 6.2 litre V8 430bhp
Uprated LS3 6.2 litre V8 - 520bhp
Stock GM Gen. IV LS7 7.0 litre V8 540bhp

Transmission - 5 or 6 speed H Gate
Typically 5 or 6 speed Porsche 911 family transaxles. Sequential options can also be installed.
Differential - LSD 3.44:
For frequent track use the Porche differential unit is quite often changed in favour of an ATB LSD to provide better traction and neutral handling.
Brakes - AP 4-pot Ventilated
Brakes are dual circuit non-servo assisted as standard. Optional bias adjustment is available for track use.
Modular Roof - GRP Composite and Perspex
The windscreen is specific GD design, E marked with integral demist element, bonded in to a detachable housing to work in conjunction with the canopy system.
The canopy comprises a clear rear cover with integrated high-level brake light, bulkhead partition, roll bar cover, T-bar connection with air intake, roof panels and door side screens.
This uniquely engineered solution allows the owner to use all components in which ever configuration they choose. The car can be used with the full system in place providing all-weather protection or driving with the roof panels removed for the targa experience and that sensual excitement of wind in your hair with that V8 soundtrack. Completely removing the whole system takes minutes should you wish to drive your car in the classic open-racer form on track days.
