GR55 - continued
1. All new chassis construction. Highly advanced materials and lay-up allowing lower weight but increased stiffness, impact resistance, and safety.
2. Gould own designed gearbox. Based on a highly successful F1 gearbox we have designed a gearbox capable of withstanding over 350ft/lbs, using proven Xtrac transverse internals, our own cam and pawl differential, maintaining high strength, rigidity, and reliability.
3. A new rear wing construction features significantly improved load capacity and stiffness. The lower mounting is removed from the airflow, giving noticeable aerodynamic gains. A top F1 style exhaust exit helps air flow in this area.
4. R&D work identified a monoshock suspension design that has several key dynamic improvements. We can now make the best of modern tyres using a simple and lightweight assembly. Again Gould built dampers allow high levels of tuning.

A number of engines can be fitted to the modular rear end but originaly the Nicholson McLaren 3.3 then 3.5XB power unit producing over 650bhp, combined with the ultra lightweight Gould chassis, made the GR55 a double championship winner.
