Question: roof panel

[Eagle_Gene]

Does anyone know how to properly shim a roof panel? I'm having trouble with roof panel breaking loose from frame in front..

C4 roof panels do not use shims and are not designed to be shimmed. If your roof panel is "breaking loose" either you're not installing it and tightening the bolts with the car on level ground or the roof panel frame or windshield header are damaged.
