California ProKart Challenge

S4 Driver Weight Goes Back to 415– And a 440lb S4 Class is Considered!
Tuesday, 03 February 2009 20:00
As you probably know, we conducted an S4 driver weight survey at our first ProKart Challenge CalSpeed race on Jan. 24th.
 
Based on those results (and feedback from potential S4 racers), we have decided that it would be in the best interest of fair competition to change the overall class weight for the S4 class back to the previous 415 lbs for the balance of the 2009 PKC So Cal season. 
 
This change will be effective with our next race at Willow Kart on Feb. 28th, and will be reflected on our website shortly. We are also in the process of surveying the Nor Cal S4 drivers from last year, to be able to make a final decision on that region as well. If you have comments or questions regarding this change, we welcome your input! Please call our office at 951-491-0808 or email us at This e-mail address is being protected from spambots.

We also wanted to let you know that based on feedback from the field, we are seeing demand for an even 'heavier' stock Honda class in our 2009 PKC So Cal lineup -- what Tom is calling a '440 Magnum' class, with a total minimum weight of 440 lbs.
 
If you or anyone you know would be interested in running this class, please let us know right away. If we get enough interest, we are willing to add it to our race schedule -- and the series championship.
