They also perform the role of a heat sink much better than drilled, potentially leading to more effective application of friction, and thus, longer brake pad life. But that should not be the primary reason to go with slotted, since longer brake pad life can be easily improved with better pads (better friction material).

I think it all depends on how much torque your engine makes, whether your dampers are 1/2/3/or 4 way adjustable, and what brand & weight of oil you are using.

I was under the impression that your brand of head/neck restraint directly impacted brake wear?

I don't think there's any magic to slotted vs. drilled vs. solid. If you have "better" braking, you might go through pads quicker, thus more brake dust. The only way I would think for you to truly generate more dust is that you've had more friction and thus wore more pad away, meaning you got more braking out of the deal. Just a theory of course, but I'm assuming everything is a balancing act. Me, I want slotted so I can get rid of those crazy holes that keep cracking toward the hub and outer edge!

Thanks guys. I have a set of Girodiscs that I will be installing in the spring before track season and what made me ask this question was seeing in my head the slots cutting across the face of the pads on every rotation of the disc and wondering if it acted like a planner slicing off a bit each time. I have dealt with the cracked drilled rotors enough. I will be using Pagid yellows, they work for me.

the rotors are two piece floating and last twice as long as the drilled. the drilled rotors on my car crack to the edges in two days of racing. So for me in my experience in a car similar to yours I go with the slotted, your results may vary.

VR, something happened to your post... the words got all misplaced, out of order, or mis-spelled...
It depends on how much wheel torque your rotors make.
It's not the weight of your oil, it's the weight of your engine.
...
It's whether your pampers are 1/2/3/or 4 way adjustable, because it's during those sphincter-testing moments that brake pads get their most extreme use!

LMAO at Charlie B and Ervtx!!
Larry, I have had great experience with Girodisk rotors on a big heavy fast beast that I used to take to the track...
