Tino rear caliper carriers (scrappy)
Tino rear discs (£30 for pair)
P12 rear hubs (£40 each)
Custom cut ali axle washer (£10 for pair from LaserMaster)
The rest is a guess. But P12 front hubs if they fit, and redrilled front discs, unless you find other discs to right spec, in fact S13 discs might be 280x22mm and will be in 4x114.
