With the s13 setup you will be running an extra 40mm track over all I measured it all up.
My setup I pretty much have up and running just need to sort out steering linkages. But I'm running modded bluey crossmember (chopped bluey mounts off welded DR30 mounts on), bluey rack with s13 tie rods on the ends, s13 control arms, s13 adjustable castor rods with a few mods to mounting possie's.
I have driven my mates bluey with this exact setup running similar camber & castor settings to what I will be running and over all it aint too heavy non power steer, I have driven worse. And the steering lock is unbelivable. But if worse comes to worse I have a z31 power steer rack which is almost identical to bluey.
