It never fails to see a number of drivers in contention for the headline shifterkart title on the SKUSA Pro Tour. Many of the previous nine championships were decided in the final laps or even the final corners. Andrew Bujdoso is searching to be the ninth name added to the list of SKUSA champions, heading into the SummerNationals leading the Pro Shifter standings.

Bujdoso will be running under his family’s Checkered Motorsports banner this weekend, and Andrew told us on Tuesday evening that he will still test his Solo Kart in pre-event running on Thursday. He also stated that there is an option for him to jump into an “Italian special” tabbed as a CM Kart, if needed. This is obviously a developing story that we’ll follow all weekend.
