To be fair Maars, that is exactly how I thought before, so much money etc etc. But in all honestly I didn't realise how much difference coilovers make. My cousin has KW V2s on his TT and my other friend has Gaz ones on his Clio 172 and they completley transform the ride. The best thing is they are height adjustable and damper adjustable so at whatever stage you're not happy you can alter it. Where as with springs, its just what height and you ride you have, thats it!
Up2 u obviously, just telling you from my experience....
