I have the QA-1 set up on the front of our '66 Chevelle conv. with Global West arms. Nice set up. They have been on the car for about four years now and I have had no problems at all. The adjustability is great as well. You can soften it up for cruising or tighten things up if you want to autocross.
I am running the 550 springs as well and the car weighs 4,002 lbs with me in it. Big block w/aluminum heads, auto, & A/C. Could use more spring for agressive driving, but these work so well on the street I'll probably never change them.
