Did the Ford Rally Team run that set-up?? I can't imagine it.
That is a Turbo-Technics conversion. Myself, Tony Turbo and a couple of others on here run them. As I understand it, it was a kit that was retro-fitted to non-turbo Mk4's when they had TT conversions in the late 80's.
Not sure what has happened to the fitment of yours, but mine is nowhere near the gearbox. Must just be to do with the 50mm drop. That's FAR too much for an RST IMO and will detract from the performance benefit of fitting this ARB set-up anyway.
HTH.
