Dave if your at the Petit on Saturday i can show you
If not as Pedros says swap the wishbones around so they sweep forwards, then remove 3mm off the wishbone which is at the rear of the car, and add the 4mm space onto the hinge pin between the front hinge pin mount and wishbone mount.
If your drive shafts are straight when looking down on the car, then you got it right
@ Pedros, car looks spot on, lets hope the brace arrives asap. Btw i noticed on the photos you have a spacer on the inside of the front camber links, might be better to have the spacer on the outside so the links have less of a angles ?.
