got it. the plastic duct. i too took them off. they just rub off. and i did trim the bacing plate on rotors. after jumping curbs few times, they will simply disappear.

 

I'm running the RSS control arms both in the front and rear so both of my front and rear OEM brake ducts were removed. What path should I take to get some brake ducts back on? Pick up some cup car ones and modify them?

 

Call RSS; I think they have special brackets that fit their control arms.
