To help answer your question 90 Accord I agree with what calesta said when he said that most of them are not constrected the best way. So Im sure they that would work, but for a short time. Like Calesta's experince bottoming out one time he crushed it. My buddy bought a set of strut bars off of ebay for like 80 bucks but you can tell the manufacturer didnt do to much R and D on them. They work still but not as well as they could if they were made with the correct material and develpment. So really to make a long story short, you get what you pay for.
