two words: weight distribution
im not talking about a car with mushy suspension, somthing with firm suspension. unless you run some big tires on the rwd car, it will be easier to break them loose than the same power on fwd. about a year ago i test drove a 94 mark viii, i could easily break the back end loose, nothing on my car, just a little on the 94 sts, 93 etc and 94 eldo base (northstar though). the northstar is not only has more torque, but better gears (3.71 vs 3.0
. the northstar cars did have firmer suspension, but a softer suspension would help with the wieght transfer of a rwd car.
