The 14th season of the California ProKart Challenge is set to begin February 2-3 at the Buttonwillow Raceway Park. Round one of the six-race championship series kicks off the flagship regional program for Superkarts! USA, coming off a successful inaugural SKUSA Winter Series event in Florida. The 2018 season for the California PKC program is a year of additions and changes based on the progression of the SKUSA organization and the sport itself. Among the changes include an expansion to 12 classes, a new numbering system to help both staff and spectators, and new trophies to be presented during the award ceremonies following each event.

Friday, 05 January 2018 11:44

In just one week, the 2018 season will begin for the Superkarts! USA organization as the inaugural SKUSA Winter Series kicks off at the AMR Homestead-Miami Motorplex in southern Florida. It is the earliest start to the season for the organization in almost 20 years, which continues to expand its national and regional schedule in an effort to reach all four corners of the United States. The California ProKart Challenge – SKUSA’s flagship regional program – is also slated to begin in less than 30 days, opening its six-race championship chase at Buttonwillow on February 2-3. New for the California PKC in 2018, and also for the SKUSA-affiliate Los Angeles Karting Championship, will be the X30 Super Master division.

Revised Number Plate Dimensions
Written by John Motley - National Tech Director   
Saturday, 30 December 2017 15:23

Due to the difficulty of using the CIK specification numbers on Cadet bodywork we are modifying the requirement in Rulebook Section 20.2.2.1 to "at least 5" tall with a .750" stroke". The competition number shall be bordered by a yellow background of .375 minimum. No other modifications to the specification is allowed. 
 
2018 Membership and Kart Number Changes
Sunday, 26 November 2017 11:45
With growth comes a few challenges and difficult choices. SuperKarts! USA hasn’t been a stranger to either of these things during the past few seasons. After several lengthy discussions, we’ve decided on the following changes to better serve our growing customer base and expanding promotional efforts.

Calendar-Year Memberships
Starting in 2018, all SKUSA memberships will be good for the calendar year only. This means January 1st through December 31st instead of an expiration date 12 months after purchase. In order to simplify this transition, we will do the following.
  • If your current expiration date is between Jan 1 and June 30, 2018, your 2018 Membership Renewal will only be $50.
  • If your current expiration date is between July 1 and December 31, 2018, your 2018 Membership Renewal will be free.
In order to take advantage of this offer, you MUST submit an online renewal during the renewal periods described below.
  • The transitional renewal period for members will be December 1st through January 31th.
  • The transitional late renewal period will be February 1st through February 15th. Late renewals will cost $125.
  • Renewals after February 15th will be treated as new memberships.
  • New memberships will be $150.
The standard renewal rate for 2019 Memberships will then be $100, and the standard renewal period will then be December 1st through Jan 15th and the standard late renewal period will be January 16th through January 31st.

CIK Kart Numbers
Starting in 2018, SKUSA will be standardizing to CIK number specifications. This means solid yellow number panels and solid black numbers for all classes, 1 digit for champions, and 2 and 3 digits depending on your class. No more letter designators. Please refer to SKUSA Rule 20.2.2 for the dimensional specifics. Our use of the video marshalling system is the main catalyst for this change, but we’d be remiss if we didn’t point out the difficulty of our track officials reading some of our color combinations and your custom number panels.

IAME Classes Shifter Classes
Micro Swift - 10-99
Mini Swift - 100-299 (200-299 reserved for overflow)
X30 Junior - 700-799
X30 Senior - 300-499 (400-499 reserved for overflow)
X30 Master - 500-599
S1 - 100-199
S2 - 200-299
S3 - 300-399
S4 - 400-499
S5 - 500-599
S4SM - 600-699
KZ (SuperNats) - 4-99

Reserved Numbers
I know what everyone is now thinking, and there is no easy way around it. We will no longer be reserving race numbers with your memberships. Each class will be assigned a block of numbers and when you enter your first race of any series you will pick from any available numbers in that pool. That will then be your “reserved” number for the rest of that series. Thankfully, MotorsportReg allows you to pick numbers in real time. You are likely to have a different number in the Winter Series, PKC and ProTour, so first come, first serve.

The 2017 California ProKart Challenge wrapped up the season at the largest finale in series history. A record total of 193 entries contested the two-day Streets of Lancaster Grand Prix on September 30-October 1 to complete the California PKC six race events, as the 11 different series champions were decided. The flagship Superkarts! USA regional program will now honor the title winners and the entire championship podium at the 2017 California ProKart Challenge Championship Awards Banquet, set for October 28 at the BeX Bar & Grill in Lancaster, California.

For a fourth time in his career, Billy Musgrave will be receiving the #1 trophy for earning the most points in the Vemme Kart S1 Pro Stock Honda division. Musgrave was able to outlast S1 rookie Hunter Pickett and Matias Podboj to earn his fourth championship in five years, thanks to three wins and three runner-up finishes. Pickett came away with his first S1 victory along with Podboj, while Nic LeDuc stole the finale round at the Streets of Lancaster. Sixteen-year-old Nicky Hays was able to defend his crown in the Formula Works/CompKart X30 Senior championship race. Hays won the opening round in Buttonwillow, adding two more podium finishes to secure the championship leading up to the finale in Lancaster. Second in the standings is Michael Avansino, recording his best finish in the championship and earning his first career CPKC victory during the CalSpeed weekend. Andrick Zeen finished the season in third, highlighted by five top-five results.
