Phoenix 2015 Digital Edition

Beautiful weather greeted the EKN staff in Phoenix this past weekend for the second stop of the 2015 season, and for the Rotax Challenge of the Americas.
 Nearly 100 drivers took part in the third and fourth rounds of the six-race championship series, set to crown champions next month in Sonoma, including four ticket to the 2015 Rotax Grand Finals. It was nearly 100 degrees difference from that of the northern portion of the United States and parts of Canada to the picture perfect conditions in Glendale, Arizona at the Phoenix Kart Racing Association. The chase for the Rotax Challenge of the Americas titles was amplified on Saturday, as five of the six point leaders scored race wins at the PKRA.  Canadian Marco Kacic scored his first COTA win to break the point leader sweep, taking the checker in Mini Max, while Sabre Cook (DD2), Christian Brooks (Senior), Paul Bonilla (Master), Nick Brueckner (Junior) and Diego LaRoque (Micro) all defended their point leads. Sunday’s racing provided a great end to what was a phenomenal weekend, finishing off the first half of the series and beginning the second, setting the stage for the final two rounds in Sonoma next month. Four of the six feature winners took their first checkered flag of the season – Mason Marotta (Senior), Matt Jaskol (DD2), John Crow (Masters), Payton Durrant (Mini) – while Robb and LaRoque added to their win totals for the year.

Re: Rotax Mini MAX Squish Change

As you may know, we at the MAXSpeed Group are always trying to listen to our customers and some have been unhappy with the current Rotax Mini MAX regulation in regards to the minimum squish gap. In trying to make this class as level playing field as possible, we have come to the conclusion with the help of our customers that the performance of the package has declined.

Our intentions are high and with current tests we know we will be able to provide all Rotax Mini MAX competitors and their supporting teams with a solid baseline coming with the new EVO products. However, the first races of the season would suffer if we were to stay unchanged; therefore, after some careful and data-filled testing at the Homestead Karting facility this past weekend, we have come to the conclusion that the current 2.8mm squish setup is not suitable. MAXSpeed Group has decided to lower the minimum squish to 2.4mm, as this will increase the level of performance to a level we are happy with for winter racing at both the annual Rotax Challenge of the Americas (COTA) and Florida Winter Tour (FWT).
