MAC rear lca's? ASAP please

[Ju5t_B3at_Me2005]

ok i bumped into this kid today at the gas station and inquired about my car. when i told him that the silver firebird was mine he immediately said "get a stang." so i laughed and said "nope i'd take an ls1 over a stang any day" anyway he said he worked for thunderbolt motorsports down here, and we talked about his old iroc z and how he has these MAC lower control arms for 82 or 88 -2002 f-bodys. he said he would let me have them for $100. so what i want to know is this: although MAC makes mostly stang parts, how are their suspension pieces? is this a good price and will they make a big difference for me? i know i don't really need them for traction cuz i dont have enough power to warrant it, but what about the handling? is this a worthwhile buy? i want to know asap because im going over tomorrow to see them and the shop and talk with the kid. so please help me out guys its much appreciated. thanks
