Pre-Entry Cutoff for Monterey is Tonight!
Monday, 28 August 2017 08:44
I know everyone is busy getting their SuperNats entries in, but don't forget Round 5 of the ProKart Challenge is this weekend at the Monterey Bay Karter's track in Marina and the cutoff to pre-enter on MSR is tonight at midnight (walk-up entries are more expensive!).  Full event details are available on the Monterey Event Page and you can still reserve a pit or camping spot at the SKUSA Store.  The weather will be mild, in the mid to high 70's and Albacore Tuna is in season at many popular seafood restaurants in the area - which means you should invite your friends, family and significant other and buy them a pit pass.

The California ProKart Challenge returns to action for the first time since the beginning of July, gearing up to host Round Five of the championship chase. The Monterey Bay Karters facility in Marina, California on Labor Day weekend will welcome some of the best racers in Superkarts! USA regional racing. The unique course will see racers hitting the track on September 1-2 in the five IAME and six Stock Honda categories, all with championship chases to be defined even further prior to the series finale at the end of September at the Streets of Lancaster Grand Prix.

The championship still remains up for grabs in the Vemme Kart S1 Pro Stock Honda standings. Three-time champion Billy Musgrave has secured three victories and a runner-up finish over the first four rounds; however, SKUSA Pro Tour winner Hunter Pickett has kept it close. The two are only separated by 115 points heading into Round Five, with Round Four winner Matias Podboj needing another victory to put himself back in contention. Formula Works/CompKart X30 Senior championship chase is still in the hands of defending title winner Nicky Hays. The gap is only 108 points in that fight with Round Three victor Michael Avansino as the lead challenger. Andrick Zeen still has an outside shot, needing more podium success with a little help.
