2022 ProKart Challenge Round 3/4

CalSpeed Karting Center

About this event

Entry Fees (Single/Both) Rounds

$356 / $662 - Classes on Evinco Blue Tires
$367 / $684 - Classes on Evinco Red Tires
$135 / $220 - Without tires.

The retail price on all Evinco/MG tires has increased by $10 per set.

MPORTANT UPDATE: With all of the shipping challenges we’ve faced over the past year and the increase in Evinco tire shipments to our affiliated series in California, Colorado, Texas and Mexico, we’ve always been able to have enough tires on hand. Unfortunately, we’ve been hit with massive delays in both boat and air shipments that will affect availability of Rear Evinco Blue tires for this weekend’s Pro Kart Challenge race at CalSpeed.

Cancelling events is not in our nature so the only other option is to run Med (Evinco Red) compound tires for the KA100 classes. We will of course do this at no extra cost to you and if you have any new Blue compound tires you were planning on practicing with, we will swap those out for you.  Micro and Mini competitors will not be affected. We are also not able to get any MG tires here in time for the same reasons.

Our apologies, we've been working very hard the past 2 years to avoid this, but we had a string of unexpected delays.

Complete details are available on the ProKart Challenge Section of our website.
