Hi Rick,
Cross drilling the rotors is to get rid of the gases exhuding from the pads
when they get so hot they gasify so you'll have less brake fade. Not at all
likely they will cut down on the warping and may damage the pads. You just
need a bigger heat sink or better cooling than these rotors. Make sure your
rear brakes are fully operational and are doing all they can do.
Just traded a set of competition cross drilled WW rotors for some hubs a few
weeks back. I'd had them for more years than I care to admit!!
Later, Paul A

think I will investigate cross drilling the rotors instead. What I was
hoping for was a improvement in disc warping. I seem to always have a
warped disc after going to the mountains. My next problem, are the holes
drilled into the rotor at a angle or straight? I can set up a indexing head
on a mill to drill the holes evenly, it just makes it easier if they are
straight. I would purchase the cross drilled rotors from Moss but they are
not available for a wire wheel car. If memory serves me correctly the hubs
a deeper then on disc wheel cars.
