I don't know what the hilux model is exactly. R12? Something like that. Others would know.
If you are going 15" wheels then definatly get the xt130/pug/hilux strut brake rotor combo. There is a lot of info out there and it is the G-O. As far as I know you don't have to shorten the strut.
I have 13's so I am basing everything around the ke55 strut. I can't go the xt/pug etc. combo as it won't fit under the wheels.
