MG Tires Extends Partnership with Superkarts! USA in Conjunction with Release of New Spec Race Tire
Tuesday, 11 January 2011 01:00
Continuing what has been a prosperous partnership for many years, MG Tires and Superkarts! USA would like to jointly announce that they have extended their spec tire relationship for 2011 and beyond. In addition to the Brazilian manufacturer serving once again as the official tire for all SKUSA events, including the second edition of the Pro Tour and the company’s growing number of regional series, the 2011 season will mark the debut of the new specially branded MG-SK ‘SKUSA (white)’ tire, which will be utilized in all official Superkarts! USA events (except for the TaG Cadet class, which will remain on the MG-HZ ‘red’ tires). The new MG-SK tire is based on the proven and popular FZ compound, with only a small compound change put into effect to extend the durability of the tire. The new tire also comes with the official ‘SKUSA’ markings in the mold, further cementing the connection between the two companies.

“Our long relationship with Tom Kutscher and Superkarts! USA is extremely important to us and we’re very happy to have been able to continue our partnership,” offers Wagner Rossi, the owner of WR Motorsports, the North American importer for MG Tires.  “We are excited to see SKUSA’s continuing growth with their Pro Tour and, of course, the SuperNationals in Las Vegas. In working with Tom for 2011, we have made a slight compound adjustment at his request to provide their racers with increased durability in the new MG-SK, and we know that everyone will be very pleased with this year’s race tire.”
SKUSA and PKC Rule Changes for 2011

Rear Protection:
Effective January 1, 2011, all competitors in SKUSA events are required to have full width rear protection (see below).  We realize that some may not have time to install the necessary protection by the first PKC events this year. Accordingly, we will allow an additional period for competitors to conform.  By the second scheduled race in both regions, you will be required to have the rear protection installed.
ProKart Challenge Programs Announce Discounted Entry Package
Thursday, 06 January 2011 10:03
As we enter the new year, the Superkarts! USA staff is back at work and gearing up for the 2011 season, one that will certainly be the biggest in the organization’s history. SKUSA is focused on building off a solid 2010 campaign, and will once again promote official competition on both the regional and national level. Interest is huge – thanks to the massive success of the 14th annual SuperNationals in Las Vegas – and big increases in support and participation are expected in both the ProKart Challenge series and the second running of the SKUSA Pro Tour. One of the primary goals for 2011 is to make the PKC program the best value in California.

The organization is vocal in its dedication to providing the best karting experience in California through their ProKart Challenge North and South programs, and a significant decrease in the entry fee package is the primary promotion. The schedules will be very exciting this year, taking the PKC competitors to a number of tracks that have not been part of the series in the past. The PKC South and PKC North calendars will feature six races, each of which includes the popular West Coast Shootout at Santa Maria in late August. The PKC North program will venture away from Infineon Raceway for the first time to visit cornerstone NorCal tracks like Dixon, Prairie City, Reno and Atwater, as well as a venue in Monterey. The South circuit will follow suit, making its debut at Adams Raceway in Riverside, while also heading back to Qualcomm Stadium in San Diego, Buttonwillow Raceway and both the Streets of Willow and purpose-built kart track at Willow Springs.
