i think its all in how you drive it as to whether the rear end will slip out on you. i know alot of ppl with older mustangs(69 coupe, and a 70 mach 1) that the rear end slips out on pretty easy. in the rain if you tromp it, sure its gonna go nuts, you just gotta have a head on your shoulder and take care when driving. also when its dry if you get on to it, just dont rev it up and dump it, launch it properly and it shouldnt go out on you to bad, at least no in stock form. im not sure with heavily modded cars how they react cause i never drove one, but i know with my dads stang it runs well into the 13's and i have no prob keepin it straight, thats just what i think about the rear end slippin out. then again i know i guy whose stang runs 14's and he cant keep it straight, so your dad might be right, but from what i have experienced you shouldnt have a major problem fordkid
