At this point, I am planning on running stock rotors. Picked up my Brembo 87 OEM replacements for $35 ea.
Allzim (in Bedford Tx) can gas slot and/or cross drill for about $38+ each.
If I do anything other than run stock, I will slot them. crossdrills tend to generate cracks in my experience...not sure how much would really be gained cooling wise.
Cross drilling will cause your rotors to run hotter. Less thermal mass + less metal = hotter rotors. Since metal conducts heat much better than convecting air, you want as much metal as possible to keep your rotors happy.
I've run the cheapest Paragon rotors without any issues either. They're blanks, no slotting.
