Street fighters

The race occurred by the end of season and Chevrolet and Ford were separated by a single point. The race would feature a big fight between the two manufacturers. Chevrolet had two very potent cars for Jack Baldwin and Willy T Ribbs, while Ford had Scott Pruett, Pete Halsmer and Bruce Jenner in Roush prepared Mustangs. Toyota also could do well in such a race, counting on agility. Scott Pruett would put his Ford Mustang on the pole in 1m39s194, followed by Dennis Aase Toyota Celica. Third was Willy T Ribbs, with Jack Baldwin V6 Chevrolet Camaro alongside. Pete Halsmer and Craig Carter Pontiac Firebird were next. The race was promising, and would prove exciting. At the start, Scott Pruett would cheat his first row partner and jumped into the lead, while Willy T Ribbs blew past Dennis Aase. He would pass Scott Pruett after the hairpin, while Scott Pruett lost balance. Both cars tangled slightly during action, and Willy T Ribbs was waved a furled black-flag, but he could go on and had a 2s78 lead after 15 minutes. Then Bruce Jenner would lose his engine and oiled the track at turn eight. The track got slippery and Willy T Ribbs and Scott Pruett got past without damage. It was not the case for Dennis Aase who slid into the barriers. The car was history. The yellow flag was set for 16 minutes.

At the restart, Willy T Ribbs still led, with Scott Pruett, Pete Halsmer and Jack Baldwin following. Jack Baldwin would hit Pete Halsmer's Ford Mustang in an attempt to pass him. He also got a furled black flag for being too aggressive. But Pete Halsmer would lose fourth and fifth Gear and become an easy prey for Jack Baldwin, as it turned out. He would accelerate and become the fastest driver on the track. He was soon on Scott Pruett's heels and both drivers would accelerate, side by side. This resulted in a brutal shunt into the guardrail for the Chevrolet Camaro. The Ford's left rear tire was also hit, and he had to pit for a new one. He dropped to seventh place. The yellow was set once again, and Pete Halsmer had moved to second place, in spite of his gearbox problems. The chequered would be waved while under yellow, which helped a lot, in Pete Halsmer's case. Willy T Ribbs won the race, with Pete Halsmer finishing second, and Craig Carter Pontiac Firebird in third place, with a heavier car. Chris Cord was fourth in his Toyota Celica.

The GTU race within the race was run on smoother terms. Bob Earl had put his Pontiac Fiero on the pole. He Led until lap 23, then hit a concrete barrier. Roger Mandeville inherited the lead, while being stuck on his heels. Terry Visger, Bob Earl's teammate, would climb up to second place later in the race. He would maintain his position until the chequered. Behind them was George Alderman, who ran somewhat quietly, and Tom Kendall, whose goal was to run out of trouble, which he did. He would let Karl Durkheimer pass him, and finished fifth. He clinched the GTU title, at 19, becoming the youngest champion in the series history.
