racing isnt about having equal rules. It is who can do what to make their car faster than everyone else... Its total bullshit these days. If everything was stock... there would be no chevys winning period. They are about 3mph slower than any other make, Because they fail to R&D.. so to make it fair... and good entertainment Nascar mandates diiff rules for diff makes of cars. I state again the only reason gordo.. or Jr or jimmy johnson win.. are because Nascar changes the rules to make them fast...
