I was in a tinkering mood tonight . . .
Every so often I need to access the center screw securing my servo saver. I have my PT mount in the factory location which until now has required removal. PITA. So I drilled the holes in the CF where the 2 side screws that secure the PT are out to roughly 2.7 mm using a 7/64 inch bit. Then I used 2 longer 3 mm screws and 4 mm shims under the PT to raise it up. I did not use the center screw. (2 screws is plenty to secure the PT)Now I can use my 2mm wrench from the front of the car and go under the PT and bumper to access the center SS screw without removing anything.
I also seem to lose the cool blue .5, 1.0, and 2.0 mm shims used for RH on the 10R5. So I happened to look at my Mi3 and had a great idea that works. I used a longer 3mm BHS in the bottom of the arm mount, and included the .5 and 1.0 mm shim between the screw head and the bottom of the chassis. This way I always have the shim I want, and I never have to look for a different length screw if I make a dramatic change in tire size and/or RH. Be careful and test fit things as you want as much screw in the aluminum mount as possible without having too long of a screw that will bottom out on the screw that runs perpendicular above it. Now as long as I always use all of the shims somewhere on the screw, the screw always threads into the aluminum the same amount
Thought I'd share.
