*sigh*.. a really good 60 ft wont affect your trap speed.. take for example the wRX.. a good 1.80 60 ft will allow it to run a 12.9@103 where as other cars such as my mach 1 trap higher.. but run a lower ET..

trap speed is a direct result of the power to weight ration of the car.. and takes in to effect all the crap you mentioned above.. trap speed is why kens supras 11.6 @130 was so damn impresive.. trapping at 130 means your makin quite a bit of power..

on the street.. generally.. in an even situation.. the car with the higher trap speed will have the better power to weight ratio.. and *should* pull the other car from a roll.. factors such as driver etc will vary this..
