im fairly young (mid 30's) and have always tried to respect the opinions of the majority of people on here and can tell those who know and those who think they know and zip has always been one of the "he knows his do-do and prolly more. And in any form of motor sports ive seen the shift from using your brains and ablity to big bank account/deep pockets in order to both be competive and just have fun. I grew up dirt track racing and back road drag racing where i guy could slap together a cheap car and run what ya brung and be competive. heck now even at the street fight here you got guys bringing barely legal cars with 700hp and twin turbo cars. One local guys 4th gen firebird payed local garage to look the other way for his inspection so it could be titled and liscensed in va to race at street fights.
