Hello - I've been lurking for a while. I found this site while searching for suspension info and found Ron Sutton's excellent write ups. I'm not sure if my project qualifies as a Pro Tourer, though. It's an old Austin Healey based kit car from the 80's that I picked up cheap. It started as a simple rebuild, but has morphed into a full blown redesign.
I am resigning the Mustang II front suspension with my own longer control arms and narrowing the rack. The rear will be a narrowed Explorer 8.8 with a 3 link. Power will come from a 383 stroker and a T56 6 speed. The engine is still just parts right now. The suspension is under construction. I have some parts built, but I'm still working on the geometry. The downside is that it is limited on tire width, though.
Here's a pic of it before I blew it apart for the rebuild.
Mike
