nice, you should take some pics of your mud cover you built, i love to go mudding but everyone around here scared me out of doing it in my VX because of fear of ruining the alternator...

i have read this in car magazines (not sure which one), but they say that when drilled rotors get slim, they have a tendency to crack around the drilled places (thats what's meant by weakened)...and actually if i remember right i read that in an article on the first gen STI vs. the newer STI (first gen had crossdrilled and slotted Brembo brakes and the new STI has 'subaru' braking system that is ceramic pads but not drilled or slotted) and that is the reason the newer STI's no longer have the drilled and slotted rotors...(dont quote me on that though, and it could also be that they estimated around $1200 for a brake job on the first gen STI because of the Brembo brakes)
