ODCC Thunder Stock Rule Clarification

For Immediate Release
March 25, 2019

There have been some recent questions to the ODCC in regards to chassis fabrication and the five tracks associated with the association would like to make the following clarifications:

Chassis Fabrication:

The main frame rails that need to be fabricated on a Camaro from the front clip back must be made of square / rectangular tubing with a minimum cross section to 10” (i.e. 2”x3”, 2 ½” x 2 ½” etc.).  This must extend from the front clip to the front leaf spring mounting point.

The same rule already exists for replacing stock sections of a metric frame car.

On both styles of cars mentioned above the 10” cross sectional frame rail must run from the front clip to the spring mounts.  For fabricated frame rails aft of the spring mounts square tubing is still mandated but smaller tubing may be used but not less than 2” x 2”

Off Set Chassis:

Under ODCC rules there are no off set chassis allowed.  Our definition of a non-offset chassis that the two center section frame rails must be symmetrical in the car and the equal distance from the centerline of the car and the four main connection points of the cockpit must originate off these frame rails.

We as a group are aware there are a few Brighton cars and maybe others out there with offset cages from history but we are addressing that in the following means:

  • Existing cars must register cars prior to the 2019 season so we have them on file.
  • No new cars will be accepted after the 2019 season.
  • The weight percentage rule also addresses this and we as a committee will review and add weigh penalties as we feel necessary.
