The Motorcar Offered
This 1983 Grid-Porsche S2 is was built to compete in Group C races by GRID Motor Racing in England. The Grid S2 was the second of two Group C prototypes built during a partnership between Giuseppe Rise and Ian Dawson, whose initials were combined to create the Grid name. The chassis was designed by former Lotus engineer Geoff Aldridge and features a monocoque that incorporates aluminum honeycomb panels. Bodywork is constructed using glass-reinforced plastic, and a twin-boom nose design was utilized for Le Mans and other early races before the car was fitted with its current solid nose.
The car was campaigned by Dudley Wood and Charles Ivy Racing in 1984. It first competition outing was at the 1000km of Silverstone in 1984. At the 24 Hours of Le Mans, where it was driven by Dudley Wood, John Cooper, and Barry Robinson. It retired after 10 laps due to a fuel feed issue. It was also entered at Silverstone, Miami, Mosport, and Monza. Its best finish that year was at Brands Hatch for the British Airways 1000 where it finished in 11th place. This racing history is documented by scrutineering paperwork from Le Mans, RAC recognition paperwork for Grid Motor Racing, and FISA paperwork.
The car was purchased by its current owner from Can-AM Cars in St. Louis, Missouri in 2012. It has since completed a multi year restoration by Max Crawford, and Mike Colucci.
An air-cooled, twin-turbo 3.2L flat-six from Porsche powers the rear wheels via a Hewland five-speed manual transaxle. This current power plant is based on a 1980 Porsche Turbo unit, and features twin turbochargers with custom impellers, internal wastegates, and Porsche billet pop-off valves. The engine which was rebuilt to an 8:1 compression ratio is currently being refreshed for the 2021 racing season.
The restoration of the chassis was entrusted to Max Crawford of Crawford Composites in Denver, North Carolina, and Mike Colucci. The braking system features AP Lockheed magnesium calipers and was overhauled by John Hayworth of Pro-System Brakes in Moorsville, North Carolina. The suspension includes rocker-actuated inboard coilovers, and the shocks were rebuilt and dynamometer-tested. A new air jack system was also installed.
The bodywork was stripped, repaired, and finished to a high standard in blue and yellow, which was the livery that it wore when it was being campaigned by Wildwood Racing. A high-downforce undertray is fitted to the car, and a low-downforce tray is included with the sale. A new windshield was also installed during the refurbishment.
Inside the cabin, a single seat on the right side is equipped with a six-point Sparco racing-harness, and additional safety equipment includes a FISA-approved roll cage and a fire suppressant system. The instrumentation was rebuilt during the refurbishment with new electrical wiring installed and complemented by a Personal steering wheel.
After the completion of the restoration in September of 2019 the car was displayed at the Chattanooga Motorcar Festival, and this past year was also on display at the Amelia Werks Reunion. Eligible for a such prestigious events as the Le Mans classic and the Porsche RennSport Reunion, this potent Porsche powered Group C Prototype is worthy of close inspection, and consideration for the upcoming 2021 racing season.
Due to the fact that the car has not been extensively track tested it is recommended that it have a full mechanical inspection before its next race outing.
Interested parties should speak with the Bonhams specialist team about the opportunity for personal set-up requirements and testing at Carolina Motorsport Park.
