I haven`t had chance to weigh up the fronts yet Martin. But I`m planning on fitting the complete s13 rear subframe, diff, suspension, shafts etc complete. I`ve been measuring up the floor pan because I`m undecided yet wether to transfer this (from the back of the transmission tunnel to the boot slam panel) or just use the strut towers and subframe pick-up points. I know that the complete s13 rear axle is a little wider, but that doesn`t matter as I will be doing some extensive bodywork (including rear arch extensions and possibly even rear tubs).
Hope that all makes sense

. Plus I`m looking at coilovers all round too.
Regards,
Ian.
