New Rules Package Additions To Debut At Michigan/6/10/16
NASCAR
will debut rules updates for this Sunday’s race at Michigan
International Speedway and use them again in the July 9 contest
at Kentucky Speedway. The rules package developments are part of an
industry-wide collaboration to further enhance the racing.
Recently,
welded truck trailing arms and new brake cooling rules were put into
place. The following updates to the rules package will
be added at Michigan and Kentucky to further reduce downforce and
sideforce:
·
Reduce skew generated sideforce by setting rear toe to zero (same rule used in the NASCAR Sprint All-Star Race)
·
Aero package tweaks to reduce aero-generated downforce and sideforce
o
Spoiler shortened from 3.5 inches to 2.5 inches
o
Splitter reduced to 2 inches
o
Resize of deck fin to match spoiler
The
current rules package has generated some of the closest racing in years
through the first 14 races of 2016. Highlights include
three races setting track records for green flag passes for the lead,
as well as two races featuring the seventh-closest margin of victory in
NSCS history (since the advent of electronic scoring in 1993).
