i'm after some front ones too as i messed mine up taking the orange but out (please dont take too much notice at gaydon!). I filled out a request on the breakers web and got a few calls back, the cheapest was £150 and then someone offered me the IS300 ones for £200.
But, i'm going to get soem JDM ones from Alex I think. Or, i might get some standard ones and get them painted.
