This is the letter I received in response to a ??? I emailed Powerslot Rotor Company.
I asked is there any way they could cut a rotor with slots for me, even if I sent them a GM rotor. So if we have any Powerslot fans here or want an awsome set of rotors can we get a bunch of you to email Powerslot and see if it will help. If not I think I will practice up and cut some GM ones myself so they match the front.



Hello
Thank you very much for your interest in 00 Bonneville SLE rear Power Slot
rotors. We do not have immediate plans to offer rear Power Slot rotors for
the Bonneville SLE, but I will survey our distributors and if sufficient
interest exists, we will add the Pontiac Bonneville application to our R&D
list.

With Best Regards

Sounds like a generic response to any question they get.

Plus I think slotted rotors have a bad rep around here. I believe WilWren can confirm this and give you elaborate details if need be.

Powerslots have a VERY good rep here. Perhaps over all other rotors. Particularly on the Zilla.

Sorry, I was thinking of cross-drilled rotors I think. THen rock on guys...

RSM rotors suck. I tested the first set for the Bonneville.

Oh its a good thing you corected that will cause i felt a whoopin comin on.( JK Sully1742 )
Yah Ive run Powerslots on lots of stuff now and have loved em lots, especialy with Hawk Pads. So if I can get some support that'd be great.

I think it should be noted that most good brake companies are able to make cross drilled rotors that will not crack, and are not weaker than slotted or smooth rotors. I have yet to hear about a slotted and drilled rotor crakcing form a reputable company. I wouldn't doubt that a set of ebay rotors would do that, however,

I've had slotted and drilled rotors on my bonnie for almost a year now, and they have performed great. They havn't cracked, and I usually drive like an *******.

It should also be noted that you won't see any performance increase from them. I bought them because they look great. Mine have the same stopping power(maybe a little less, but it'* not a noticable difference) as OEM rotors. Just don't expect to get some great 60-0 stopping times with slotted and drilled rotors.

yeah, also with drilled and slotted rotors, or any rotors, is when theyre new, to have them "cryoed" which is freezing them so that all remaining moisture and any other this are taken out using something like liquid nitrogen or something related. just freeze em and let em thaw to rrom tempurature and theyre good to go. i new a kid who for some reason had some liquid nitrogen lying around and i did it and i t seemed to work, but i didnt see anything special but i had read about it so i thoguht what the heck. but im pretty sure there are places that can do things like this for ya

now im not exactly a rocket scientist, but I know that when you freeze water, it expands, and will break almost anything in its path, rotors notwithstanding.

So to me, freezing rotors to get out moisture might do more harm than good. But I guess theyre subjected to freezing temps anyway. So I dont know what to think of that.

The cryo treatment has nothing whatsoever to do with moisture. Only hardening and strengthening the steel.

Drilled rotors give up surface area. Surface area stops your car. Give up that idea.
