The Colorado Karting Tour is proud to share the Summer CKT iRacing League! If you’re jones-ing to get some virtual racing in against real drivers at race tracks across the globe, this is the league for you!

This is brought to you by Concept 3 Racing:

Who we are and what do we do? 

The CKT iRacing League was formed in 2019 by a passionate group of Colorado Karting Tour drivers and was a great success with full grids and high-level competition from CKT drivers as well as their close friends and family. Starting in 2021, the CKT iRacing League opened membership to any Colorado resident or those in nearby bordering areas with the aim to become the premier iRacing league in Colorado.

How do I sign up?

If you are already set up on iRacing proceed to Step 1. If you are not already set up with an account or are new to sim racing, please visit the CKT iRacing League Facebook page or Discord server and ask for information on getting set up. There are also some additional resources at the bottom of this page.

Step 1: Click here and request to join the Colorado Karting Tour iRacing league.

Step 2: Install the Free Driver Information application based on the instructions here. Once installed fill in as much information as you can and follow the instructions given to have it running during the race. This information will be used by our broadcasting team during our live events so be sure to share some fun facts about yourself and do not list anything that you don’t want to be shared on a live broadcast! Note: The page you are taken to has a subscription footer on their site for their other applications. The Driver Information application is free.

That’s it! After those three steps are complete you are ready to race… But, there is more! The following steps are highly recommended. They only take a minute, please see below.

HIGHLY RECOMMENDED (borderline required) NEXT STEPS:

  • Join the CKT iRacing League Facebook page. This is where most discussion regarding the league takes place. Ask questions, speak with the community, make suggestions, and maybe get some pre or post-race banter in here. In addition to the iRacing league page on this is the secondary location where the latest information is released and is a great way to learn about any changes, news, or updates happening in the league. Click here to join.
  • Join the 403Racing Discord server. While in-race communications will use the built-in iRacing voice channels most of our racers also use Discord as a way to communicate, set up practice sessions, discuss the series, and really just keep in touch with others from CKT. Our broadcast team will be using this channel for post-race interviews with the top 3 drivers of each race so this step is a highly recommended step if you plan on winning… and you do plan on winning right? Thought so. To join, click here.  

IF ALL ELSE FAILS, and you just cannot get set up with the information on this page, have an unanswered question, would like to be a sponsor of the series, or just want to chat, please send an email to [email protected].

2023 CKT iRacing Summer Championship 

Season Details and Schedule: 

This year we’re doing a summer CKT iRacing series brought to you by Concept 3 Racing. 9 points events and a special intro non-points event that will be used for any tiebreaking. To make it extra interesting we’ll be doing different car classes at different events. The two classes will be the Toyota GT86 on a fixed medium downforce for the heat races and the GT3 on a fixed medium downforce for the non-heat races. The GT86 races will be on shorter iRacing-included circuits while the GT3 races will be on longer tracks which were picked due to being close to a similar F1 race day. Since participation varied last series we’re going to add AI for the GT3 races. We’ll also be doing some inverted starts, some rolling and some standing starts, and a team endurance race. The series will be doing 1 drop.

Round 1:

Participation only, no points, just tiebreaker, not a drop event
There will be 2 sessions: 8 PM and 9 PM
8 Cars:

  • Toyota GT86
  • Kia Optima
  • Formula Vee
  • Dirt Street Stock
  • Dirt Legends
  • Dirt UMP Modified
  • VW Beetle
  • Pro Lite

Open Setup
