You can't get hold of them now they stopped making them.... When they first came about you could buy them from eBay, but ktec suddenly bought the last 10 sets of them put the price from £170 too £200 (although the extra £30 seemed to cover a proper warranty and uk supplier so made sense) and then rumours came out they were identical too the ktec coilovers and the raceland ones just ceased production. Second hand is the only way too get them now, and I have never seen a set come up so they can't be that bad
