The Thunderhill Open Returns!

The Open is a celebration of everything modern grassroots track culture — club racing, drifting, time attack, food, vendors, games, live stream, and evening hangs. It’s kind of a golf spoof too, so no trophies, but the now coveted Green Blazers will be awarded to the winners. Some other golf jokes too, probably.

We are thrilled to include Global Time Attack into the Thunderhill Open - The friday test day registration happens here, but GTA competition registration information can be found here: Global Time Attack

Road Racing Classes - Road Racing Schedules and Tech forms can be found here:

Non-Traditional Class Collections

We’re doing something a little different. Instead of housing, operating, and policing seven rulesets (including drift) that each have their own cultures and quirks, we figured it’s a better experience for everyone if we just go straight to the experts.

We’ve partnered with race groups directly — but separately — so these group leads will be in charge of rulesets, tech, and pre-event questions specific to their class.

Group 1 – Western Touring Car Championship - team@wtccracing.org

Group 2 – Formula Awesome - Mark@worldspeed.com

Group 3 – Heatwave Retro NASCAR - Justin@heatwavevisual.com

Full Course Drift - Drift Cave - danielc@driftcave.com

Global Time Attack - jd@globaltimeattack.com

Road Racing Format

A single practice session Saturday morning, a Qualifying session
Four heat races
Finishing position from each heat sets your grid for the next
Heat 3 finish sets your starting position for the Main
The weekend podium is based on the finishing position in the Main only

Heat races will be 6 laps (not time-based), and the Main is scheduled for 10 laps.

There will be a Friday test day available as an add-on option during registration.

Spectators
Every entry comes with an additional GA credential for a guest of a driver. Any additional crew, guests, or spectators over the age of 12 will need to secure a General Admission ticket - or if you are a spectator looking for General Admission ticketing, all of that, plus pre-event merch can be found here: https://thunderhillopen.com/
