Track Time – Updated Rules and Classes Promise a Great Year for Goodguys CPP AutoCross
Buckle in and get ready to hit the track, because the Goodguys CPP AutoCross Series is back and ready for action as we prepare to kick off the 2022 event season! New classes, updated rules, and a revised structure for end-of-season awards and shootouts are sure to shake up the status quo and make this an exciting year
for both the dedicated AutoCrossers who follow the series, as well as more casual racers and participants to want to give it a try.
We’re thrilled to have Classic Performance Products returning as the CPP AutoCross Series sponsor. The company’s support gave the series a major performance boost in 2021 and will continue to help us provide the best competitions possible at 15 events this season. 
You’ll see the company presence through logos, banners, and other materials, and we hope that when you see a CPP team member at an event you’ll thank them for their support.
Another sponsor we’re happy to welcome back is Wilwood Disc Brakes, who will sponsor the AutoCross Stop Box this year. 
We all know precision braking and stopping are critical elements of AutoCross racing, so it’s a natural fit for Wilwood to have its name on this important area at the end of the track.
In an effort to keep Goodguys CPP AutoCross fun, competitive, and as fair as possible, we’re constantly listening to racer feedback and evaluating the class structures and rules to see where we can improve. There are quite a few changes this season, so we thought it made sense to highlight the most significant ones on the following pages to get everyone up to speed.
