So. I guess for some reason. Mine have that nasty grime in the holes, in the slots, and right around the hub. it is especially noticeable around the rear hubs, because for some reason the pads they sent me dont make full contact. does anyone else have this problem? is this something that i should contact them about and complain?

 

drilled rotors will always be weaker than slotted / regular ones.

what do u mean by dont make full contact?

 

What brake pads did you get? I got their brake upgrade kit for the 8 and it's been great. I got the Hawk HPS pads, the contact area of the stock pad is slightly larger than the HPS but they still make good contact and stopping power. You will have the rust color ring right around the center of the brake rotor because of this if that's what you are talking about. That color will show up in the drilled holes too since the pad doesn't come in contact with the inside of the holes to burn it off.
