Is this soot normal?

do you guys think it has anything to do with the little vents in the rear bumper? Like brake dust getting through there? I also removed the little square paper filter looking things that are underneath the trunk lining near the fender wells...I had no idea what those were for.

Yes, the vents help but the dust comes from the front of the car too. Every time you hit the brakes you are wearing off a layer of the material. It ends up all over the back of the car because of the way air flows over it.

the rear bumper vents are fake!

i had the same stuff accumulate on my rear too after i put on res tp's. once they broke and i went back to the factory cats the problem lessened. the black stuff i see now is tire that comes off during heavy driving.

i would put those paper filter things back. they are for airflow of somesort and the paper part keeps crap out of the cabin. (if these are the same items im thinking about)


i made a thread about this awhile back. basically make sure your rear tires are aligned and yes the TP's are making it more dirty.
