Sunday, March 22, 1998 – Dale Jarrett’s victory in the TranSouth 400 at Darlington (S.C.) Raceway was just the second victory for a Ford team in the season’s first five races, but it came on the heels of a second NASCAR rule change aimed at taking away a perceived aerodynamic advantage the auto maker enjoyed on the race track. Earlier that week, officials had instructed Ford teams to decrease the width of the spoilers on the back of their cars by two inches. Eight of the top 10 finishers at Darlington were Fords.
• NASCAR had previously required Ford teams to decrease the height of their spoiler from five inches to 4.75 inches after the auto maker swept nine of the top 10 spots at Las Vegas Motor Speedway.
• At Darlington, spoilers on Ford entries were decreased from 57 inches wide to 55 inches, the same as that on Chevrolet and Pontiac entries. Ford teams placed five or more teams in the top 10 in all of the season’s first five races.
• “We built a good race car and all they’ve (NASCAR) done from the second race on is take stuff away from us,” Jarrett said afterward.
• Ford drivers led all 293 laps in the TranSouth Financial 400 at Darlington.
