Due to the pending forecast for the Super Grip NHRA Thunder Valley Nationals, we have adjusted the schedule.

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 10th.

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 only if you withdraw before the June 10th deadline.  Please email Michelle Sieradzki at msieradzki@nhra.com to initiate the credential refund.

During the period of 1:00 PM PT on Monday, June 8th through 1:00 PM PT on Wednesday June 10th, no additional entries will be accepted for this weekend’s event.
