AutoCross has become a staple at many Goodguys events, including the 8th Spring Nationals here in Scottsdale. While many racers take to the track on Friday, Saturday is when the real gear smashing, high rpm, car sliding action happens. Once the green flag dropped, close to 50 lead-footed drivers took to the course, steering their machines through the cone maze while a full grandstand of spectators cheered them on throughout the afternoon. It was a great day of racing as four of the five classes crowned event champions by day’s end.

Tomorrow is all about K & N Filters ALL American Sunday. It’s a great opportunity for late model owners to enjoy the show & shine or put your driving skills to the test on the Goodguys AutoCross course. All American vehicles and American powered cars are welcome. Registration opens at 7am. See you bright and early! See the champions along with our complete AutoCross gallery below.

PRO Class

Ridetech 48 hour Corvetter driven by Chris Smith

The PRO class action was as hot as the asphalt during the first two days of the 8th Spring Nationals. Under sunny skies, RideTech’s Chris “Smitty” Smith took a commanding lead over the rest of the field with a fast lap of 34.277 that stuck for the win. Nipping at Smitty’s heels was Greg Thurmond’s sleek ’65 Corvette and the always “Fast” Mary Pozzi in her ’72 Camaro.

Four of the top five PRO drivers were running RideTech’s new Instinct Electronic Shocks. Debuting here in Scottsdale, the new shock design has been in the research and development stages since June of 2016 at RideTech’s Indiana headquarters. Veteran AutoCross racer Mary Pozzi, a 12-time SCCA Solo National Champion, says “it’s the best my car has ever handled.” Check out the new Instinct shock at
