you say cheap so im guessing secondhand,I bought secondhand coilovers for my e39 and only bought them as they passed nct on previous owners car,when they arrived I brought them to garage to fit and they wouldn't saying the top mounts were gone and they probably have leaks as the rebound on the rears was slow or didn't happen,advice is not to buy secondhand,the guy I bought them off was genuine and he refunded me no problem,he was supprised though as the nct cert showed them perfect,I bought indigas e36 last week and its on joms and very low,collected the car in meath and drove to mayo,lovely on ok roads and motorway but on crap roads they not so good.had planned on getting new coilovers for my e39 but definitely wont now,would ruin it in my opinon....
