I'm guessing that once you fix them, they will work better anyway....?

I would stay away from the slotted rotors, studies have shown there is little to no gain in stoping power with them. On the other hand, drilled rotors make a conciderable difference in braking performance. Just stay with the drilled rotors without slots if you are looking for better performance.

Ummm....no. Drilled rotors are not a viable option for track use. Slotting helps clean pad deposits and are almost required with modern race compounds, but drilling should never be used.

Drilled rotors are how you end up with a cracked rotor.

So that must be why brembos and high performance cars come stock with drilled rotors... I guess all the car companies dont know what they are doing, since almost every high end model has them drilled. Porsche, mercedes, corvette, etc... But hey, if you say so. In general, for everyday driving slotted have little to no Performance gains... Drilled decreases stoping distance and have more bite. I know that the slots divert brake dust but thats all they do, there is no decrease in stoping distance and no extra bite. I have done my reasearch on them and have seen multiple studies that show the same thing about drilled vs slotted...

Drilled rotors are for show. Go look at the production based endurance racing and tell me how many drilled rotors you see. The OP is talking about track use and under those circumstances, drilled rotors are not what you want.

Slots do not just divert dust. They reduce build up when the pad melts.

I know what the OP was talking about, with my experience having drilled rotors on multiple cars I know how much better the braking and stoping distance was. I have never had them crack once, even with track use... You get what you pay for... Im not talking about getting those crappy ones off ebay thay are made in China. Anyways, im done arguing. I got better things to do, just wanted to let the OP know that I have used solid/drilled and slotted rotors and my best experience has been with the drilled, period... Merry Christmas!

Back in the 60's-70's, some race cars had drilled rotors because for the most part rotors weren't vented and volatile pad compounds needed holes in the rotors to keep from outgassing at high temperatures, but these days pads are made from some really high-tech stuff and don't really even need slotted rotors. I know more track-day enthusiasts that use vented blank rotors and high-tech pads because they work better.

Drilled rotors look cool, but offer zero benefit on the track.

There is no published evidence to support otherwise.

One advantage to having slotted and/or drilled rotors on a street vehicle is that your pads will likely wear more evenly and you will be less likely to experience brake squeak when using ceramic pads.

Will an 05-06 spindle go on a 01 focus?
