Please follow the instructions below for further information on how to deactivate your auto renew option:
If you initially purchased iRacing directly from www.iracing.com with a Mastercard, Visa, American Express, Discover or PayPal, you can cancel your membership by logging into http://members.iracing.com and click on Account.
Login to the Account, on the My Account home page, scroll down to the Billing Options section, click the "Click Here to turn off auto-renew" link. If it now says "Click Here to turn on auto-renew" - you have successfully turned off auto renew.
This will turn off the auto renew feature and your credit card or PayPal account will not be charged the next time your subscription expires.
If you purchased iRacing using PaymentWall, you will need to contact PaymentWall Support to turn off the auto renew and cancel.
If you purchased iRacing from Steam, you will need to contact Steam Support as iRacing and Steam have two separate purchasing processes.
