I called it "World Sportscar Racing '92", because (as already mentionend in the SWC 1991 thread) it includes cars from several championships, namely SWC, FIA-Cup (they raced together), JSPC and IMSA.
Today I finished the line-up (kicked two FIA-Cup teams and added two IMSA teams). I know that the set is not 100% realistic, but sadly the grid of the SWC was not big enough to make an own set. The compromise is a set including the fastest cars of the sportscar world in 1992 (except the Gebhardt C91, which was probably the worst sportscar in '92).
