Best CSL Parts?

IMO the trunk is too heavy. They should makes it lighter since it's higher on the car and leave the trunk floor similar to non CSL instead of making it in cardboard to reduce weight...

Battery was also lighter, muffler was also lighter, backglass was thinner.

It’s not cardboard.

It’s not cardboard.

It's not sheet metal either. Please post pictures of yours cause we never had CSL on this side of the pond.

It is, by trunk floor they meant the thing that you can lift up to access your tire inflator kit.

That's correct, the boot floor/rear axle carrier is the same as the M3 & suffers with the same cracking issues. On my car the whole panel was replaced by BMW in 2013. The actual panel that you lift to access the the tyre inflator is some sort of honeycomb/paper construction. More detail here:
