Ah ok magic (thanks for the caliper setting too), I've not looked at it yet so wondered if it was all held together through the bearing carrier etc and had a big nut on it. The discs have arrived and I see the mounting holes now, cheers.
And yeah, shakey steering wheel under braking. I was hoping it was just pad deposit on the discs but it's persistant and I've tried some 'hot' runs and heavy braking to try and remove it without success. My fault, brain went out the window during a couple of session at Oulton Park and I didn't do anything like a long enough cooling down period before pitting although they have done a few other track days so it could be too much abuse for them (with my over keen braking probably).
