Im trying to get my head round this upgrade to the S2.

I have a set of Sierra 2wd Calipers with 4mm machined off the mounting face, plus a 283mm Sierra 2wd Brake discs & pads.

Im reading through the Sticky thread and its getting confusion as its jumping between 2wd,4wd,st170 etc.

So i guess its just a matter of drilling and tapping the hub to m12 bolting everything up and bleeding the brakes plus by the looks of it to keep the standard S2 alloys will need a wheel spacer to clear the caliper.

any help would be great.
