lots of choice out there dom but you don't say why you want coilovers and what you're aiming for? ie track car, road car, slammed/stanced, handling, ride quality, budget etc? what you want to spend and what you're trying to achieve might mean the difference between a recommendation for some ebay "coilyovers" at 100 notes or some bilstein clubsports at a couple of grand.
Want a set for road use but a bit of everything as well haha ones that handle nice, good ride quality, can go really low, not too hard and crashy! Looking to spend about £500 I'd say!
