the front offside wheel bearing was buzzing / grinding when i turned left hard so i assumed the wheel bearing.
I changed the wheel bearing (upon removal the old one was f*cked) so i thought sweet and marveled at how i am the king of wheel bearing changes only to fing that the buzz / gring was still there!

Any ideas?

Funny you should post this, I am having a bit of an issue with this atm myself.

Thought it was the front bearing but seems i was wrong, all the symptoms of a bearing but they are all ok.

Have a look at the metal dust shield on the back of the disc.

i was wondering if its a caliper slider issue in my case, they are a bit worn and a small amount of play can be felt, wondering if its just the pad touching the disc slightly with lateral g force.

/\ what he said.
My old one was rubbing in the disc at the bottom. Just had to bend it out with a screwdriver and all was well- though it just drew more attention to the other rattles and noises I had! :o:

hhmmmm mine has the 740 calipers and 320mm disc convertion and no dust shield so it cant be that. the exhaust down pipe runs extremely close to the front wishbone end maybe the down pipe could be touching?

This is true, I had bridgstones and they were noisy as hell, with pilot sports 3 nothing at all!

Is the tyre rubbing on anything inside the arch?
