havent personally ever had a set of qa1's but know they make quality stuff. i have run the edelbrocks though and was very happy but i would recommend them for a car that doesnt see a whole lot of track time as they are not so much 1/4 mile oriented (they are better for ride quality and handling). i am currently running comp engineering 3-way adjustables on all four corners of my car and have been very happy with their street and strip manners.
