For those of you who want 114.3mm stud pattern on your coupe (as I did to use some rims I already had and match the GSR brakes on the front.)all I did was use a pair of rear hubs of a CB GSR FWD.You then need to make a sleeve to fit the stub axle for the inner seal to work.Any machine shop can make these and did for me while I waited.The size of the sleeve is 28mm inner bore and 40mm outer.Thickness is 8.8mm and is as narrow as you can go.Inner bore must have a radius on one end of at least 3mm.You then MUST shim your calipers to center to the disc as the track has been increased app 2mm.As I already had the hubs on hand the total cost of this swap was $10 a side.I hope this helps a few of the guys who are on a budget and limited income which the greater majority of modders are.(or should I say wanna be modders lol)
This is the sleeve

The sleeve fitted.You could ask for a shrink fit when making this for a more permanent fitment and seal.

The hub after fitting.Spins free and firm.

And with the disc and caliper fitted.Note this caliper of a FWD GSR is not suitable as the handbrake cable will foul the trailing arm.A CC GSR or Evo will do the trick. The disc will be a CB item machined down to 249mm.A custom bracket can be made to keep the original disc size which would be a better option.A m21 or satria handbrake cable should be used although a cb one can be adapted with a little jigging about to run the cable in a slightly longer route.I have run this set up with about 10.000km with no probs at all.
