Power Slot rotors/cryogenic treatment....any opinions or experiences?

[ELVA164]

Hey all,

So I'm doing a bit of early research about new rotors and pads for my '87, and I found a company called Power Slot that appears to make rotors at a reasonable price point and with positive reviews on other vehicles. Has anyone here installed them? How were they?


Also, they offer a cryogenic treatment for the rotors that is supposed to improve rotor life and performance. Has anybody had this done to their rotors? Any input there?

Thanks!

If your DD'ing the car just get full brembo blanks, a nice set of [pads front and rear, rebuild calipers, and do a fluid flush with some good fluid. I have been told spece30 guys run similar setups and have great experiences.

Actually a lot of Spec E30 racers use the cheapest plain rotors we can find. They last as long as the more expensive one and perform identically.

Plain OE type rotors are good as it gets in terms of performance and life.

So the slots aren't that useful on a DD and the cryo treatment isn't really that helpful? Glad I asked, thanks!

I have found that slots on the street are not very effective. Some may argue this, but my experience is that they will fill up with brake dust/material over the course of DDing and essentially become nonexistent.

Cry-treatment will increase the life of the rotor, but for a DD it may be overkill. Like others have said for race use, I use plain OP Parts rotors, the cheapest rotor I can find, and have had no complaints with the set I bought for this year.

So I looked around some more, and I think once I get around to it I'm going to get a set of Centric rotors, Stoptech Street Performance pads, new wear sensors, and maybe ABS sensors to see if I can get that light to turn off...

@seatown, I dropped the thought of the slots soon after that post both because of your reason and because I feel that they would just increase pad wear/dusting due to the relatively low operating temps. I can't get the cryo treatment option out of my head, but I think that's just me being stubborn for no good reason.

Thanks for the help!

The Powerslot rotors are good quality but I agree with the above on just going with Brembo blanks.

[ELVA164]

So everyone has mentioned Brembo in particular for the blanks; is Centric one of the "cheap" rotors with lower-quality steel or would those work alright?

[jlevie]

Cheap rotors are less than $30 each. At $46 each for Centric rotor I would not call them cheap. The quality of the steel has little to nothing to do with the life of the rotors. So any plain rotor will be fine and the less expensive the better.

The life of a rotor in other than a race environment will be determined by when the rotor is worn below minimum thickness. And that will be mostly determined by the pads used.

[MR 325]

Centric parts are good.

Centric rotors also look good, which may be a factor in your selection of a rotor for street use.

Great, thanks for the help guys! :up:
