I am also on a budget problem, i am a student, i been searching for coilovers on ebay and there are so many to choose from, there are expensive ones and inexpensive they all look the same. my questino is whats the difference? does it matter which kind i buy? I want a reliable coilover that would last me for a long time. Please help thanks
