 The chassis was designed by Giorgio Molinari while the suspension was designed by Gianpaolo Dallara who had recently joined Maserati.Early testing revealed handling problems which were solved by adding a homokinetic joint to the suspension system suggested by Bruce McLaren, one of the drivers of the Cunningham team.There were also ventilation problems and excessive rear tyre wear which were never resolved because of lack of proper testing due to the cars being completed shortly before the LeMans race.
