Tri-C Karters has been a mainstay of southern California karting for over 50 years, providing a family-oriented racing environment for novices and veterans alike.

CalSpeed Karting was southern California's premier karting destination, providing a clean, modern facility and superb track surface with nine configurations. Due to the closure of CalSpeed, Tri-C's final race in Fontana was October 15, 2022.

K1 Circuit in Winchester, California will be the new home of Tri-C's primary club series beginning in 2023. All registration for Tri-C events take place on MotorsportsReg 
The 2023 Tri-C season will begin at Apex Racing Center and continue at K1 upon their opening.

As you know our new home for the Tri-C Club Series (formerly at CalSpeed) in 2023 will be at K1 Circuit in Winchester. We're excited and looking forward to this!

However, we are going to start the Tri-C Club Series season at Apex Racing Center in Lake Perris on a race-by-race basis. When K1 opens, the season will continue there. We made this decision based on feedback from racers/teams this winter as well as discussion with the general manager at K1 Circuit concerning track opening date.

*Membership will open on January 25th. Priority membership/class numbers/seniority member pit spots (available only for those not racing under a team tent) will be available until February 12th. After that all kart numbers/member pit spots will be assigned while supplies last and on a first come first served basis.

**Rounds One - and Two will be at Apex Racing Center. 

***ROUND ONE is Saturday (practice)/Sunday (race) February 25-26th 
***ROUND TWO is Saturday (practice)/Sunday (race) March 18-19th

1.)         The weekend format for the Apex events will be Saturday "karts only" open practice run by Tri-C Karters with racing on Sunday. We do not yet know if we will continue this Sat/Sun format upon moving to K1 but would like to if able and if drivers prefer it.

2.)         Race format will be practice, qualifying, a 12 lap pre-main and a 20-lap main. (this will be our new race format going forward). 

*CLASS LIST for 2023:

Kid Kart // TaG Micro // TaG Mini
LO-206 Jr. // LO-206 Sr. // LO-206 Master
100cc TaG Jr.// 100cc TaG Sr. //100cc TaG Master // 100cc TaG Grandmaster

(KPV will no longer be an option at the club series - as of right now we are still offering it at our winter series at Adams)

*Tires will remain Hoosier this year. Oil is Motul or Elf. Fuel is VP.

If you have questions or anything is not clear PLEASE reach out to us. We are more than happy to clarify or discuss any of the items above. Thank you for your patience as we navigate this transitional year.
