alter rules for 305 Sprints, Trucks
By Brian Liskai
FREMONT/ATTICA, Ohio (Friday, Nov. 2, 2007)
- In an effort to try and
contain and control the cost of racing
and keep the competition equal and
fair to all participants in the 305 sprint
and dirt truck divisions, Fremont
Speedway and Attica Raceway Park have
teamed up to implement a few rule
changes for the 2008 season.
In addition, Fremont Speedway will be allowing
teens, 14-years-old and up,
who have a minimum of two years race experience
(i.e. go-karts, quarter
midgets, etc.) to compete in 2008 - at
the promoter's discretion.
"After talks with our insurance company,
we are willing to allow
14-year-olds and up the opportunity to
race. They have to have at least two
years of competitive racing under their
belts and must be approved by myself
and Andy James," said Fremont Speedway
Co-Promoter Rich Farmer. "There are
some very talented drivers who have been
racing in go-karts and quarter
midgets since they were six or seven and
we want to give then the
opportunity to compete at Fremont."
"We're looking at having some sort of test
and tune day prior to the season
starting to get some sort of judgment
on the younger drivers," Farmer added.
The rules for the 410 sprints at both Attica
Raceway Park and Fremont
Speedway for 2008 will follow those established
by the O'Reilly All Star
Circuit of Champions and World of Outlaws.
Farmer said the only major
difference is a one-inch wicker bill will
be allowed on the top wings.
