I have QA1 coilovers, they weren't heavy enough to withstand the torque on the rear wheels, hitting on the edge of the fender wells, I had to put the stock coil springs back in and jack the coil overs all the way up and it still wasn't enough, I found that I didn't have enough travel on the shock stem, I had to install extensions on the coilover shocks. Make sure you measure the distants from the shock mount on the rearend to the shock mount on the frame, you need at least 2 inches travel each direction from the center after the shocks are mounted, get the heaviest spring you can buy for the rear, I am runing a Mustang GT quad shock rear and a mustang II front supension, I bought the QA1 for the Mustang II front, they didn't have enough travel either, had to extend them also, I recomend you measure the distants and buy the right length shocks to start with, like I said make sure you have at least 2 inches travel in both direction with the car setting level, make sure you give your tires plenty travel room inside the fenderwells edge.
