Ok today I think I discovered something.
I need some measurements from you guys

Can someone with the coupe bumper it's like the big hole D: shaped thing measure how high it is from the ground to the bottom of the bumper?

And someone with the sedan bumper that is the long rectangular hole do the same?

I just popped a coupe bumper on and it doesn't fit correctly on the bottom end. It seems like the coupe bumper is closer to the ground and is longer overall

Thanks.

Yeah - it's more than different covers. Some of the main internal parts, like the abosrber and reinforcement are different as well....

I've got a collision parts database,if you want to go into more detail.......

The stuff underneath the cover seems to be fine. Everything bolts up correctly except for the splash shield at the bottom and the wheel well splash guard not extending the slight 1/4in down
