the camber plate is on the top of the shock assembly. if you open the hood and take off those 3 plastic things on top of the battery and to the left and right of it you will see 3 nuts on each side of the car with a black plastic cap in the center. These three bolts are actually the mounting bolts of the camber plate. pop off that plastic cap and it will expose the top of the shock.. if you loosen (not remove) these three bolts you can push the top of the shock out or in changing the camber. the "shims" are on the control arms and are adjustable on the GT3 only. Adding shims is getting the car into a non streetable camber situation usually.

 

Ah ok that's the top mount monoball you're referring to, assume you'll fit your nice new Tarret one's rotated to give bit more camber for track.

 

coffin arm.. that is what we yanks call a control arm. funny thing is , it did not break however I do not trust it anymore! shims.. they go in the control (coffin) arm. the camber plate is on top of the shock.
I hit a curb... going fast.

 

Yep, also hit curb going fast, Swiss Alps, year before last, snapped coffin in half, had to hold up for two days waiting for replacement from Stuttgart as not a single Porsche dealer in Europe carries gt3 arms, good times, NOT.

 

some more pics of progress

 

might sound ignorant, but never saw that before

is it a frame extender, whatever you call it?

 

it is a frame machine pulling the shock tower back down a bit. We got it all back to within 1mm of factory specs. Amazing as most cars are acceptable at +/- 3mm with these measuring devices.
