I don't believe so, somebody correct me if I'm wrong. But they are beveled, and there is only one hole per cooling vane for strength.

 

thats good at least.

hmm I'm going to have to look into the willwood a bit more. would be nice to upgrade my brakes soon.

 

I'm pretty sure Wilwood also makes rotors that are just slotted for that kit.

 

Thats what i have. see pics on website. I ordered the "solid" rotor kits and was very happily suprised to get the slotted.

Many people are asking me about the "Q" pads i use.
All i can say is very very highly recomended.
I can drive a whole week and still not have any visible dust, yet it still snaps your neck when you wanna breakl hard.

For more infor on the heat ranges and other types of polymatrix pads check out wilwoods website or these guys here have lots of info on the pads, click on "more info"
