Mabbs was also offering them in carbon, I think RTR were going to take that over, not entirely sure on that though.
I could post a picture of the one I bought but it is on the list of things that did not arrive!

Thanks guys, scott that build is beautiful. I think we are going to try fabricating our panels see if they fit, what they look like then decide iit'll be fun trying a bit of panel bashing/making.

Hi Jon,
I was just wondering how far in the outer race was when you assembled your hubs?
The parallel section of stub axle protruded through the bearing before the bearing was home and there is so much thread protruding my grease caps look like they wont fit without fouling the thread.
I could of course cut a few mm off the end but wanted to see if I had missed something.

im at the point where the caps wont fit with the split pins in due to their taper, even when i cut them in length, im going to get some nylock nuts for them to use as locknuts, ill then offer up the centre caps, ill take pics on sat when i get to the car if you wish.. have a look on my build and see if they are the same as yours mate..

I reckon I could have put thin spacers under the bearings to give a wider distance over the bearing set and so eliminated the problem but that's a bit extreme to solve a grease cap issue. Wonder what others have done as the setup we have used is probably common to many of us.

I'm not sure I completely understand what you mean certainly I could not get my grease caps to fit they where the wrong diameter anyway, I'm not sure they are that relevant as i think they will foul on the alloys I'm pretty sure ned said he just left them off as they will be sealed in by the wheel and centre cap anyway, you could cover them with a placky bagin the meantime to stop cr*p getting in.
I have a bigger problem that the hub does not seem completely square to the axle as the disc moves 1 or 2 mm forward and backwards in tha caliper as I turn the disc 180 degrees, have decided to ignore this for now and take it all apart at some point and see if it goes back square.

do you mean its rotating eccentricly? are the bolts full size? 12 I think. top of my head. if the. is as tight. it should be and rotates true. then. discs. holes. as long as they. strike the calipers then shouldn't be a problem. shouldn't feel. it when its a rotating mass unless its a long way out

I interpreted this problem as a side to side movement which would indicate that the bearing is not on square.
I have not put a dti on mine but the old eyometer indicates my disks are running quite true. Mind you my eyeometer could need a recalibration as old age creeps in.

Mind you my eyeometer could need a recalibration as old age creeps in. it recalibrates automatically, if you add alcohol into the aperture approx 4 inches below the eyeometer device

No not eccentrically but axially ie in the caliper the disc moves towards one brake piston then back towards the other whilst it rotates by a few millimeter ie the angle of a line parallel to the disc surface is not 90 degrees to the axle , any explanation of the possible cause of this would be welcome

My best guess is that the disc is not squarely bolted onto the hub or the bearings are slightly skew on the axle ??

Could be the bearings on the axle or in the hub itself, but checking the bolting of the disk is an easy first check.
If that does not solve it grab a dti if available and check the run out on the hub itself which would then indicate a bearing issue, remember though any error on the hub will be magnified on the outer edge of the disk.
