Disc brake conversion kit recommendations...

There is an article in the current Mopar Muscle issue where they upgrade their 68 Barracuda drag car with Aerospace brakes front and rear. They were going from 73+ A-body disks to the Aerospace disks on the fron and drums to the Aerospace disks on the back. They saved 86 pounds.

I read that article and it's pretty neat...But, those rotors are solid, not like a normal rotor...Also, I think that car (project B3) is a dedicated drag car. I thought it wasn't a good idea to use those kind of rotors for the street?? Not sure, but enlighten me if I am wrong...
