In the world of suspension components, $50 isn't really that much. If your question is whether or not it's worth $50, I'd probably say, sure it is, even if the quality is bad. Only you can answer for yourself what you really want for your car though. Determine what you want from your suspension and go from there. A friend of mine has Matrix coilover sleeves he bought for pretty cheap. He just wanted them for looks and he doesn't race or anything of the sort. I personally wouldn't buy them but I helped install them quite a while ago and they've been fine ever since. If you do decide to buy them, inspect them carefully to make sure that they don't look like they'll break on you in some way once installed.
