Take the rear bumper off a C8 once and the shim stacks probably aren't a big deal. Take it off over and over again and suddenly fourteen piles of tiny aluminum shims scattered across your workbench become a really stupid way to spend your afternoon.
Across the top of the C8 rear bumper are fourteen attachment locations. Under those locations are the factory shim stacks that establish how the bumper and surrounding bodywork sit on the car.
One location might have no shims. Another might have several. Mix them up during disassembly and you can turn an otherwise straightforward reassembly into an annoying session of panel-alignment archaeology.
This isn't complicated. It just solves one annoying problem exceptionally well.
Every upper rear-bumper attachment point gets its own numbered pocket. Whatever shim stack comes out of position 6 goes into position 6. Revolutionary stuff.
Large engraved D and P markings keep the tray oriented to the car, while the numbered locations mirror the bumper attachment sequence. You don't need notes, bags, Sharpies or a particularly good memory.
Bright red anodizing makes it easy to find on a crowded bench, and the machined pockets keep the shim stacks separated while the car is apart.
Could this have been a plastic organizer from the hardware store with fourteen pieces of masking tape stuck to it? Absolutely.
But that's not particularly satisfying, and it sure isn't how we do things.
If you're regularly removing C8 rear bumpers for service, aero work, exhaust work, track-car maintenance or development, this thing pays for itself in reduced aggravation surprisingly quickly.
Taking your bumper off once to install an exhaust and never touching it again? Put the shims in fourteen labeled bags and move on with your life. This is a shop tool, not required civilian equipment.
Simple tool. Simple specs. No eighteen-page engineering white paper required.
