Yea, the actual suspension mounts are the same as the Spec-R ones, just anodized black instead of red like the Spec-R. Just don't use the suspension pins from the kit and just cut down the Xray ones (or get the Yok ones like you did).
Also, up front I'm running 2 dot inserts like this...

Im running 1degree toe out up front, 3.5 on the rear. 1.5mm camber all around.
I have my shock mounts at the same position as you, too. Try standing just the rears up one hole then. It'll make the car turn in tighter. Also I'm running only the front two and the rear two upper deck screws. I've got no screws in the actual layshaft, but I'm not using any captured layshafts or anything. Just no screws coming down on it.
