Don´t get drilled discs, more so if you don´t track the car and do regualar cleaning off the discs. Its only a weak point on the disc and will most likely just micro crack at those drilled holes first, making the disc more and more fragile. If you buy drilled discs for big brake/OEM kits that cost $$$$, they are cast with the holes in them. Discs as MTEC and all those cheap makes are taking blank discs, and just drill through them. Only one way that can go and thats down hill. If you go to a race track or something like that, look at what the people are using for the track, its most likely slotted discs, and if they are drilled, you can bet it has cost the bomb^^
