cars would be managed for the race by Schneider's GS Sport racing team. Brun drove his car with Siegfried Muller Jr, while the other had team-regular Hans-Joachim Stuck joined by Jean-Louis Schlesser and Dieter Quester. With the Porsche 956 not available for customer sale until the next year, both Joest and Kremer were given copies of the Porsche 936 factory plans to build their own replica versions. Reinhold Joest fitted the new 936CJ with a 2.5-litre turbo engine, and ran it alongside the older 936/77, to give Bob Wollek the DRM championship. Purchased by the Belgian Martin brothers, they ran it in the WEC with Wollek, with their red and white Belga tobacco sponsorship. After they got a third at Silverstone, Philippe Martin crashed the car heavily at Nürburgring. The rebuild gave the engineers the chance to fit a long tail and low-drag nose for the circuit. The Kremer brothers' Porsche replica, the C-K5, had a 936 frame fitted with their own Kevlar-blended sharkfin chassis and had the transaxle and rear suspension from their previous year's unsuccessful 917 project. It was fitted with their 2.3-litre twin-turbo flat-six engine and was capable of reaching 330 kp/h (205 mph). But finished at the last minute there had been no time for track-testing. They continued the productive relationship with Ted Field's Interscope Racing, and his regular driver Danny Ongais, along with the Kremer's 1979 Le Mans winner, Bill Whittington. Lola Cars, after initial trials with the T600, set about building its successor for Group C, the T610. It had a purpose-built honeycomb monocoque for the Cosworth DFL engine and a chassis made of carbon-fibre and Kevlar. Aerodynamics were fine tuned in the Williams F1 wind tunnel at Didcot. This gave it a top speed around 345 kp/h (215 mph). The works car was driven by Guy Edwards, Rupert Keegan and Nick Faure, while the American Kent-Cooke car had Brian Redman and Jim Adams with him. The Grand Touring Cars team had last brought their Mirage cars to Le Mans in 1979. They brought a new model, the M12. Designed and built by John Horsman, who had worked with John Wyer on the original models, and Howden Ganley at Tiga Race Cars. Two chassis were built, tested at the Lockheed wind tunnel in Atlanta and road-tested at Riverside. Equipped with the 3.9-litre Cosworth, they could reach 340 kp/h (210 mph). Time ran out to
