Slotting helps to prevent pad glasing and helps outgassing under hard braking.
The disadvantage to Drilling them is they are very prone to cracking.

Rep Power: 0 In response to this, true or not I do not know for sure, I would not buy drilled or slotted rotors. I was told by a friend (who races professionally) that the reason they drilled rotors originally was to reduce weight. In race cars there are gigantic rims that accomodate massive brakes. The reason they were drilled was to reduce weight. From other friends I have had, they were very unhappy with the results of these rotors on the street, because they tend to chew up brake pads at an expedited rate. Just some food for thought....anyone else know more on this subject?
it's cool down the brake and also , it's look GOOD

Rep Power: 0 like previously noted, both metods are used to cool the rotors down, as for saving weight, i havent heard anything about this.
ive also heard that the cross-drilled are more prone to breaking, but i havent heard anything like that about the slotted.
and IMO, when it comes to your cars performance, you shouldnt buy something JUST because it looks cool.

Rep Power: 380 Boilermaker1 had it right. Drilled = Cooling of the roter (Roters mfged now can withstand much higher temps.) Slotted = reduce risk of brake fade (Pads mfged today dont brakedown as quickly so they dont "fade" as much). However with the modern meterials used in brakes today you will never find it nessisary to have either on a mid to light weight car on the street. If you race a lot you may incounter brake fade (I'm taking about racing as in on the track not drag.) The best way you can improve brake performance on our cars is to get steel braded brake lines and up grade the pads to a more performance pad. other wise your just buying roters for that "look".
My policy for my car is "If it dosn't make it go faster or handle better is isn't going on my car".

I brake hard a lot, and my rotors tend to warp rather frequently. Right now I have 15,800 miles on my 7th gen and I need to get the rotors resurfaced.
After the original set of rotors on my 6th gen warped for the first time, I replaced them with some Brembo cross-drilled rotors, and they never warped again. I also put some performance brake pads on, and between the two, my braking performance was increased noticeably.
So to get back on track with the original question: Where can we get slotted or drilled rotors for our 7th gens? I've look all over the 'net and all I can find is for 6th gen and older.

Rep Power: 0 part of the reason stock rotors warp and aftermarket(basic or drilled/slotted) usually dont is because stock ones are steel which has a lower "melting" point than aftermarket aluminum ones. all drilled/slotted, to my knowledge, are aluminum.

Rep Power: 0 Try www.tirerack.com, they have brembo, powerslot, and ebc rotors and pads, as well as hawk pads too. Thats where i got my ebc rotors and pads and there is a noticeable difference in braking compared to stock, especially in high speed brakeing.[IMG]i/expressions/face-icon-small-smile.gif[/IMG]

Rep Power: 0 According to this drillled rotors are actually for less weight and it does not cool as well. Willwood faq
