If a fixed spot was available during the registration, you will receive an email to the specified email address within the next few days with further information on payment. From the receipt of this email you have 7 days to pay the amount via Paypal or bank transfer to fix your place in grid. If no payment is received within this period, your spot will be passed on to the next team in the waiting list.
If there was no fixed spot available at the registration, your team is on the waiting list. You will only receive the email with the payment information when a fixed spot is available for you. That means you only have to pay for the race when a place in grid is guaranteed!
