NASCAR increases the penalty for rear suspension infractions – Autoweek

NASCAR has decided to increase the penalty for the infraction that has encumbered two Monster Energy Cup Series victories this season.

The sanctioning body informed teams on Friday at Richmond Raceway that violations of the rear suspension rule previously broken by the teams of Denny Hamlin (Darlington) and Joey Logano (Richmond I) will now be penalized at the highest end of the L1 punishment scale introduced back in February.

Specifically, their truck trailing arm spacers and pinion angle shims were not in complete contact with the corresponding mating surface and drew an inspection failure during their respective post-race evaluations at the NASCAR Research and Development Center in Concord, North Carolina. Doing so now will carry with it a much stiffer punishment.

The infraction now carries a 40-point penalty, a $75,000 fine, a three-week suspension for both the crew chief and car chief in addition to the loss of all playoff points earned during that particular race.

The previous penalties were 25 points, two-week suspension for the crew chief and a $50,000 fine.

In simpler terms, NASCAR has recognized that teams are starting to explore exploiting this area in the rule book to find additional speed and has raised the punishment in hopes of discouraging it. A graphic of the part in question can be viewed below.
