A 30 car field would show up at the start of thé San Antonio GT race. The street course was 1.67 mile long and was also very challenging. A three make competition involved Lincoln-Mercury, Mazda and Nissan for the win. Pete Halsmer and Elliot Forbes Robinson had four-rotor Mazda RX7s, while Jeremy Dale and Steve Millen were at the wheel of Nissan 300ZX Tcs. Dorsey Schroeder and Robby Gordon drove Mercury Cougar XR7s. Thé remainder of the GTO field consisted of Chevrolet Camaros, driven by privateers. The best of them was Anthony Puleo, whose Powertron Batteries car was looking fine. The GTU class was also a three make fight, this time with Dodge being the challenger to Nissan and Mazda. The Leitzinger Nissan 240SXs, driven by David Loring and Bob Leitzinger were the favourites, but Dodge drivers were eager to tackle them. Stu Hayner and Don Knowles would try hard and take their chance. The Mazda drivers were also willing to do well, with Lance Stewart and John Finger Driving the works machines. Al Bacon and Amos Johnson both drove MX6 cars. Don Reynolds had à Nissan 240SX entered by Electramotive. A single Porsche 911, driven by Jimmy Landrum was to play second fiddle. The AAC class was quite exciting, with many Chevrolet Camaros and Berettas. A single Mercury Capri driven by Vic Manuelli would try to show its potential. Two Buick Somerset, driven by Dale Kreider and Bill Fuller did not have the ability to do well on such a track. Dan Osterholt, in a Chevrolet Beretta, proved the fastest in qualifying. The weather was kind of hieratic, and a pair of showers nearly washed the schedule. It left some time for the drivers to adjust their setup during a lull. At the start of the race, Dorsey Schroder took the lead in his Mercury Cougar XR7, followed by teammate Robby Gordon. The latter tried to get past Dorsey Schroeder, but he only managed to land into a pile of tires. He was the first to retire in the race. Dorsey Schroeder would pull ahead and stretch his lead to 15s over Steve Millen. Then the Mercury Cougar XR7 began to falter. He lost a cylinder and third gear. He would slow down and be overtaken by his rivals, but he kept going. Pete Halsmer had already grabbed second place. He had fallen in fourth place after hitting a pile of tires. By lap 17, he was now aiming at the lead. Five laps later, he was the new leader. Steve Millen's Nissan 300ZX Tc was then in second place, and kept it for good until the closing laps, but he would then experience a small fire. It would withdraw him from the podium and Jeremy Dale was more than happy to get past him, and finished second. Elliot Forbes Robinson had trouble getting into the race, but he finally managed to finish third, one lap down. Pete Halsmer took a somewhat easy win, but Jeremy Dale was closing in on him at the end, but it was too late.

The GTU class was interesting, with Don Knowles shooting into the tlead right from the start. David Loring Nissan 240sX and him engaged in a duel. It would result in a spin for both of them! Behind them, Stu Hayner's second Dodge Daytona and Lance Stewart in a Mazda MX6 were also battling hard. The latter, who was running for the championship, then decided to run smoother, so he would settle for fourth. He clinched the championship here, and was happy with that. David Loring restarted in first place, and then managed to cruise to a somewhat easy victory. Stu Hayner overtook his teammate to finish second while Dorsey Schroeder took third. The AAC class was won by Kendall Cranston in a Chevrolet Camaro, followed by Kent Painter in a similar car.
