Domination Continues for Holz Racers in WORCS Competition

Frederick, Zimmerman and Holz Clean House in Respective Pro Classes

Lynden, WA (March 11, 2009) - While the season is still young in the World Off-Road Championship Series (WORCS) Holz Racing factory backed pilots are already setting the tone as the ones to beat. When the last checkered dropped at the Race Town 395 Raceway in Adelanto, California last week, Holz racers stood atop the podium once again, besting the top ATV and UTV racers and machines in the country.
In the Pro ATV class, it was returning champion and perennial front-runner Josh Frederick from Moapa, Nevada and his Holz equipped Motorworks Can-Am besting the field with a strong performance. Other Holz Racing notables in the field included Jeremie Warina in fourth, Mike Machado placing seventh and Jesse Goss rounding out the top ten.
The results were more of the same in the hotly contested Pro Am ATV class, where Dillon Zimmerman and his Holz Racing suspended Motorworks Can-Am DS450 came across the finish line with a 2-minute lead over his next closest rival. A combination of racing prowess and excellent Holz Racing equipment spelled the difference between racing and winning. Also posting strong results was Tammy Balser, who as a young teenager showed her abilities against the typically male dominated field with a strong 11th place finish.
In the UTV side-x-side national class, Mark Holz proved again no-one designs, manufactures and race tests Polaris RZR UTV products better than Holz Racing Products. Utilizing many of the same Holz Racing UTV products available to his customers, Mark took the win while laying down lap after lap of consistent times. At one point his best lap was a full 11 seconds quicker than his next closest competitor.
"It was another good weekend for our team," said Mark Holz upon returning home to his Lynden, Washington race shop. "Our Holz racers proved once again the durability and performance of our products. In the UTV class I nailed the
holeshot… the Kroyer powered Polaris RZR is just awesome to have under your foot. The response is great and combined with our suspension and chassis products, it really puts the power to the ground."
In addition to Kroyer engines and Holz suspension goods, the Holz Racing Polaris RZR rides on sticky Maxxis Tires and has its extended range of suspension movement kept in check by FOX Racing Shox. The power is harnessed by Team Industries clutching goods.
The Race Town 395 course was punishing on both racers and equipment as it featured portions of a motocross track and open desert running with huge sand whoops
The World Off-Road Championship Series is one of the premiere off-road racing series in North America. The next race for Holz Racing and WORCS series is March 27-29 in Lake Havasu, Arizona.
