JewStangGT

ok, so i was talking to a buddy of mine about upgrading the cams and valve springs on my 06 gt as well as the rear end gears. the time came to chose the cams, and i started d looking around. comp cams makes mustang cams in stages. they all are the same price, but stage 4 gives u the most lift and hp. after doing research, i read that cams like that are too drastic for a daily driver because the car wont be able to idle low anymore. the question is more of an opinionate one. which cams are "the best" and why, also if anybody has done the comp cams "stage 4 cams" did they work out?
