As said above, there are no 17" rim options for us in North America, as the stock brakes in our RRS trims (HSE and S/C) are too large. I have seen a couple of LR3s (Disco3 to you) fitted with 17" rims locally, but only because the owners had the smaller brakes / discs specifically flown in from Europe to downsize them. Sadly, things are about to get worse with the MY2010s being launched, as apparently the new stock brakes will be bigger still, and even 18" rim will no longer fit over them, let alone 17s.
