I noticed that the rear wheel liners aren't really full and have some weird inserts front and a cavity for dirt to collect behind the wheel, I didn't really make anything out of it and if there is a reason for this design? Well, few days ago it snowed and I noticed that snow/ice accumulates in the wheel well and because of this design on both ends it has no where to go. I had to physically break the ice and remove it from there so it didn't scrub on bumps. Normally on all my other cars it would accumulate at the very front or end and all it took was a small kick for it to fall off, well not here. Has anyone noticed it, and if so what is the plastic deal all about?
