I suppose the new chase system is ok but I think that's the least of Nascar's problems.

Since I gave my F1 rule proposal on another thread I'll give mine for Nascar:

Drop engine size down to 4 liters, allow ohc and get rid of silly restrictor plates.

And, do something about rain delays which seem to ruin most races anymore (even Pheonix!). Either grow a pair and run in the rain or put a roof over the tracks. If you can't run on wet banks then either knock down the banks of race on the apron.
