1. The IAME Jr weight is 330lbs


2. In a effort to help control costs the WKA Board of Directors voted and approved starting with Road America for KA100 Jr and KA100 Sr, it will now be 1 Set of YLC race tires for the event. Tires must be new on Day 1, same set to be used on Day 2.  

We look forward to seeing everyone at the CTECH Manufacturing Motorplex at Road America for another great event!
