If i wanted top end or a corner carver, i woulda bought a vette or viper, or porsche (yea right) if i was rich, anyway maybe an earlier vette, but i dont care about handling at 100mph or doing 200 topend, thats why i have a mustang with no front swaybar and some 4.10s about to go in the rear?? because i like leaving these topend cars staring at my tailights from a stop if i can, and a mustangs aerodynamics arent for 200mph runs, and if you try this, lower your car and have some z rated tires, and be careful, im not saying it cant happen but you would dump so much money in your car you might as well just buy a vette or ls1 that can do 160+....just my .02
Low end killer torque is why i love stangs, and the t-5 was geared to leave these yuppies in smoke!!
think about it, where you gonna test the topend at? not on a public road i hope, these viper owners know what they can do, but never do it.
