Found these on eBay, looks really nice and cheap, they sell fully adjustable too for about 200£ a pair. Anyone tried them or/and have some opinion about them.

They are for quads so probably not man enough for cars.

Sorry wrong item should be this one eBay Item they come in different size and colors eBay Item same brand different seller i think.

Too soft, would need to see the spring rate, to be sure.

Try Procomp, Protechs are circa £400 or Gaz (direct) for about £350, for sets of 4.
