World Speed Selects Two SuperNationals XV S4 Drivers for Formula Speed 2.0 Test
Thursday, 01 December 2011 10:31
World Speed Motorsports, continuing their long association with the SKUSA SuperNationals, selected two S4 drivers to complete tests of the Formula Speed 2.0 at the team’s headquarters in Sonoma, California.

The first test was awarded to S4 Winner Bonner Moulton, who was the clear veteran of the field competing in his 15th SuperNationals and having a near perfect weekend qualifying P2 and scoring three heat wins in addition to the main.

The at-large pick, for his performance both on and off the track, was Robert Marks hailing from Visalia, California. Marks, capping off a season competing in SKUSA’s ProKart Challenge and Pro Tour Events, showed speed throughout -- with a consistent battle to overcome adversity finishing 11th in the main. “I’m really excited and appreciative to receive the award. I’d really like to thank SKUSA for all they do and the series they run. Looking forward to the opportunity and representing SKUSA well,” explained Marks.

The two S4 drivers will be scheduled to complete the test with World Speed Motorsports at their headquarters which is based at Infineon Raceway. The two tests are part of over $120,000 awarded at SuperNationals XV.
