All the real Gr4 factory cars that I have seen have the same sway bar set-up, the rear like in the first picture I posted (from Guy Trigauxs #2860). That includes Les Grays car and Patricks Hals Candy car # 2862.
The bars we had made were produced by a German suspension company H&R, and are true copies of a factory set of Gr4 bars that we borrowed.
The rear bar is 22 mm and 5 way adjustable with notches in the bars that the clamps slides over. The front bar is also different from the street bars and are 2 way adjustable (see picture).
The bars rotate in solid aluminum mounts on the chassis, the front mount raised some 2". The rear bar mounts are moved outward as shown in the pic in first post.
Still looking for correct clamps ...
