I need to redo the suspension on my 95 GT, and I see Mac sells a complete rear upper/lower rear control arm set,with bushings and bolts, for less than $250. This is going on a street oriented car,paired up with the Ford Racing M-5400-A Bullit spring/shock/swaybar setup. Are these control arms any good, as far as binding issues,ect. For the money,they seem like a good deal. Also, what is the advantage or switching to the 2003 Cobra front control arm?
