hi, i'm running cheap coilovers on my mk4 polo runabout, they are a make called patech, and i got then brand new for 200 notes from a german trader at a castle combe track day about 4 years ago, i've had them on about 3 years and they are spot on, nothing like damping is adjustable, but they do run helper springs all round i think they are 20lbs helpers and the main springs are 100lbs front and back. but over all if you only want something for hard road use then a cheap set is fine, if you have plans for some serious track action then go for something like kw veriant 3 or bilstine pss 9's or something like that. also one thing to think about is poly bushes if you drive hard on standard bushes with a low hard setup u can kill standard bushes quite quickly. hope that helps. also myki most common coilovers are 2.25 inch id springs but some are 1.9inch id and the are other verition on these to, so it's worth checking befor you order any other bit's.
