It is these days, the price skyrocketed about 6 months when the breakers realised what was going on with them, I was found some for £45 a side at that time but they would'nt post them out to me, kicking myself now.
Ha ha - I managed to get them for £50 apiece with carriers thrown in, but guess the project write up and several others doing it contributed to price increases.
Try phoning a few local places first and ask for 330 diesel. More common, same caliper and they don't perceive it as a performance car.
Failing that I'd reckon on refurbed at not much more.
