1998 SCCA Pro Racing World Challenge

The 1998 SCCA Pro Racing World Challenge was the ninth running of the Sports Car Club of America's World Challenge series. It was the final year before SpeedVision would purchase the series, thus giving the World Challenge a TV contract. This would lead to the series' popularity growing and ultimately surpassing that of the Trans Am Series. 1998 would also be the final year of the T1/T2 format, as Speed would reformat the classes into GT and TC.
