NASCAR has made a change to the rules package for January's Preseason Thunder test session at Daytona International Speedway in preparation for Speedweeks 2012.

The changes are from a result of information gathered during recent tests at Talladega (October) and Daytona (November).

The rules package, which includes changes to the cooling system in attempt to reduce the two-car drafting, includes:

  • Smaller radiator - Maximum of 2 gallon capacity
  • Smaller overflow tank - Maximum capacity of ½ gallon
  • Radiator inlet is moved up closer into the front center bumper area
  • Rate reduction in the springs – softer springs
  • Smaller rear spoiler
  • Base line restrictor plate of 29/32 inch (1/64 inch larger than plate size for the 2011 Daytona 500)
