At the 1993 ARCA race held at Texas World Speedway in 1993, Darrell Waltrip won in a Chevrolet and Page Jones, at 20, became the youngest driver in ARCA history to have sat on a superspeedway pole. Additionally, Mickey Gibbs won at TWS in '92 and two-time series champion Bill Venturini was victorious in '91 at TWS.
TWS has always been known as one of the safest race tracks in the country. In 1979, a NASCAR Grand National (now Sprint Cup) Stock Car race went 396 out of 400 miles before a yellow "caution" flag came out for two laps. The following year the race went all 400 miles without a yellow "caution" flag. Thus, in 800 miles of NASCAR racing there was only one two lap "caution" period.
TWS originated the rule of not finishing a race under the yellow "caution" flag in the 1977 TEXAS RACE OF CHAMPIONS. The rule provides for two finishing green flag laps to be run following a yellow "caution" period so as to not deprive race fans of an exciting finish to a race. This rule was later adopted by the USAC Stock Car Division and later by several other racing sanctioning organizations.
Ferrari introduced its new F-50 model at TWS, which was featured in the January '96 issue of Autoweek, the June '96 issue of Motor Trend, and was featured on the Motor Trend TV.
