Cheers for all the good comments.
Stef. Im not sure on the wheel colour yet. One plan may be to have two sets of wheels, one for the road that are just plain silver, then a second in an extremely bright colour for track.
Brakes work really well, although ABS kicks in a lot more now. No issues with balance weights.
Ash. Yep should have a very BIG update coming May/June, all being well.
Mike. Found them in the for sale section on here. Paid £90 for carriers, calipers, hoses and pads, then the disks were £80 from crnproducts.com.
