Slotted is for pretty and accelerates pad wear, and drilled in unsafe from an engineering standpoint, don't give me the outgassing crap either because it isn't really applicable to todays street pads. Best bet is quality blank rotors.

 

This man speaks the truth

 

I have seen the boom tubes and it looks gross IMHO....the lines just dont flow well with that just sticking out there and the bottom of the bumper up so high....now if you had a body kit and cut out a hole in the side skirt that matched the tip perfect then maybe it would look good....but on a formula firebird???? I dont see it....now a transam ws6 with a rear bumper swapped out with one thats longer and lower and kinda looks like a finned underbelly pan and custom holes in the side skirts...that would look sweet.
