  • March 21, 11:00 AM - KA Masters Added! - We've added KA Masters at 30+ 390 lbs.  There also seems to be growing demand in a KA Super Master (45+ 390 lbs) class.  If this is you, enter the KA Master class and put in the 'Notes for Registrar' the message "Interested in KA Super Master".  Once we get 5 we will add it.

Guaranteed SuperNationals Main Event Starting Position

SKUSA will again be including a very lucrative benefit to the Champs heading into the 2019 SuperNationals. In any of the classes that will be opened to 88 entries for this year’s SuperNats (such as Mini Swift, X30 Junior, X30 Senior and X30 Master) the Champ will be rewarded with guaranteed starting positions in the main event on SuperSunday. Should they not make the main following the heat races or the Last Chance Qualifier, they will start at the tail of the grid.

Priority SuperNationals Pre-Entry Program

Again in 2019 is a way for PKC participants to secure an entry for the SuperNationals ahead of their competitors – and before their class fills up! This new bonus is definitely an extra incentive for all drivers to participate in this year’s PKC. Anyone running the PKC this year will have an opportunity to register before the general public. These drivers will be part of SKUSA’s ‘Priority Pre-Entry Program’ – PPEP – which has been designed to provide SKUSA racers with a guaranteed opportunity to attend the event as a participant. 

Additional Prizes

As if the purses and prizes above were not enough, SKUSA is still actively working to assemble additional product and cash prizes from series supporters and sponsors to distribute to racers at the podium presentations of each event.
