torque, warped rotors & dust shields

["Walter" <Whalt@xxxx>]

Does anyone have any suggestions on how to put vents in the front brake
rotor dust shields? If the engineers were trying to find a way to keep the
rotors hot, then this device looks like it should do the job well. Does the
car really need such a dust shield anyway? Is it a bad idea to just leave
it off or drill holes in it or stamp louvers in it? Maybe I could attach a
heat sink from an old stereo amp? Suggestions anyone?

I am convinced that over torquing the front lug nuts cannot cause the rotors
to warp on the Delorean because the rotor is a seperate piece from where the
lug bolts attach. The rear rotors may be a different story.

My steering pulsates a lot when I use the brakes. I checked the runout on
my front rotors, and they are fine. My left rear rotor has a lot of metal
missing from the factory, and it is warped as well. I'm surprised a rotor
that bad would end up on a new car! I wonder how many hands that bad rotor
went through before it got on my car? It's like the casting had an air
space form on one side. It only affects about 5mm on the outer edge on one
half of one side, but it is certainly enough to cause the brakes to pulsate.
I don't think that cutting them down will help. It looks like there is too
much metal missing.

Does anyone have any sources for cross-drilled rotors other than Auto
Specialty?
