I'm debating which route to take myself. Slotted, Slotted/Drilled, Drilled, or OEM. From what I've been reading...
Slotted - Allows gas to escape better than OEM, but wears pads down faster
Slotted/Drilled - Best braking and cooling. Risks include cracking, and faster brake pad wear.
Drilled - Allows better cooling of the rotor without wearing the pad down faster.
OEM - Most surface area, but least cooling ability. Normal pad wear.
Now I don't need anything too extravagent. My car is a daily driver that sees the track maybe once a month if that. Overall, I think my choice is a good quality drilled rotor. I'll take my risks with cracking, as it seems that is a less frequent occurence. I'd rather have long lasting pads with the holes to help cool...if they crack...I replace them and I warn others...if not...I'll be happy.
