GTC International GT Series
Welcome to the pinnacle of our Saturday morning timeslot. This is the exact moment we have been building toward since GT Champions first hit the track on iRacing, and we are thrilled to finally bring it to life. Get ready for our biggest championship yet, featuring incredible multi-class racing with both GTP and GT3 machines.
This series will push your skills across a massive 9 round calendar. Every round features an intense 70 minute race where strategy is just as crucial as raw pace, requiring one obligatory pitstop to mix up the running order and keep the battles tight right down to the checkered flag.
For the very first time, we are introducing a $50 cash prize (which could go up to $100!*) for the champion of each category, made possible by our amazing prize sponsors DG and SS3d. On top of the cash, each class champion will also take home the highly coveted GTC Winner’s Coin. We are also bringing a Team Challenge to the grid, so you can squad up with your friends and compete for overall team glory.
Below you will find everything you need to get started. Check out the full season calendar, read through the sporting rules, grab the required decals for your liveries, and hit the registration link to secure your spot. We cannot wait to see you on the grid!
The $50 USD Prizes:
Registration for the IGTS is completely free, and everyone is welcome to join the grid. However, to help us cover the organization’s running expenses and make the new $50* cash prizes and GTC Winner’s Coins possible for both classes, we are suggesting an optional $3 contribution. If you enjoy racing with us and want to help support the series, you can make your contribution using the payment link: PayPal link
*If more than 15 drivers register for the GTP class the prize will rise to $100 for the GTP champion. If more than 25 drivers register for the GT3 class the prize will rise to $100 for the GT3 champion.
