It's currently got a set of 6" Supalites (need a freshen up) with 175x60 Yokohamas, which after scrubbing in were really good tyres, but have worn very quickly. Height wise, the front is running Escort RS struts and 145lb -2" springs. I'm sure the rear has a modified set of CD6 springs (would need to check what is left in the shed and work out what's still there) with -1.5" blocks and gas shocks.
I will post up a new thread in projects and restos when I have finished building the decking, as there seems to be very little information on rack conversions around. Found a useful thread at:
