From 1980 on a fairly large number of Lola F-5000/Can Am II cars were converted to Frissbee bodywork. I take it that the Frissbee body was a bit better aerodynamically than the T-333 bodywork. As the Can Am II series dwindled to nothing in the mid 1980s, the Frissbee was the numerically dominant car.
The "GR-3" designation, by the way, was used by Galles Racing for its Frissbee and was not a designation given to Frissbees in general. It must be said, however, that the Galles Frissbees were the most successful of all the Frissbees. Al Unser Jr won the series championship in 1982 in said Frissbee. Then the cars were sold to Canadian Tire and Jacques Villeneuve I (the uncle) won the 1983 title. The cars then went to Rick Miaskiewicz, who snagged the crown in 1985. Hence, the majority of Frissbee wins were the GR-3 Galles variant.
Also, Rosberg and South did not drive Frissbees. (Don't believe everything you read in race programs!) Rosberg drove a different Lola F-5000 variation, a Spyder NF-11, for Paul Newman in 1979. South also drove for Newman, in 1970, but in a Lola T-530. South had his career ended that year when he crashed a Spyder NF-11 that he was using since his normal T-530 was damaged in practice.
