Ultimate Converter Concepts Returns as a Title Sponsor for 2013!!

    Ultimate will be supporting Street Race for the 2013 season; which will be KOTS' version of John Sears' highly popular Ultra Street class ran up north and Ultimate Street ran down south by Donald Long. 

Instead of retiring the name of our original heads up class it will be revived as this exciting new class.  This partnership will compliment Lenny Croteau of Ultimate Converter Concepts' sponsorship of Ultra Street up north and hopefully encourage racers to travel to the sister events.  Most racers should be able to run both Street Race and Ultra Street without major changes to equipment or weights. 

When you are in need of a torque converter for any application, give Lenny a call.  He will treat you right and you can get the same Ultimate Converter race winning technology that is in the top cars of sportsman drag racing.

The 2013 King of the Streets / Holcomb Civil Wars Schedule is out!
