If I remember correctly the Phase 5 had splitters on the front guards like the HDT Commodore, it also had a roof wing, a bonnet scoop, front splitter and rear wing.
The kit was made by Phase Auto's in Melbourne (correct me if I'm wrong) At the time I thought it was extremely cool but, now that I am older, I am no longer a fan of body kit add ons.
The only Ford that I have seen from that era that stills looks incredibly tuff, was Dick Johnsons Tru Blu XD and the Greens Tuff XE. The flares, rear wing and front air dam suited the car perfectly and the car still looks fantastic alongside todays model cars. I think this is because the wheel/tyre combo suited it, however to it would require an engineers report to have wheels that big now on an XD/XE.
