Due to the pending forecast this weekend, we may need to adjust the schedule. While our goal remains to complete the event within the originally scheduled dates, weather conditions may require changes.

We understand you may need additional time to evaluate the forecast. To accommodate this, the deadline to withdraw from the event has been extended to 1:00 PM PT on Wednesday, June 4th.

If you choose to withdraw, please log into your account at www.nhraeventreg.com and select the withdrawal option for the Super Grip NHRA Thunder Valley Nationals. A credit will be issued to your account for future entry use.

All crew credentials purchased for the event will be refunded.  Please email Michelle Sieradzki at msieradzki@nhra.com to initiate the credential refund.

During this period, no additional entries will be accepted for this weekend’s event.
