Brake upgrade question.

Brake upgrade question.
I am going to upgrade my brakes and would like to hear from you on which would be the better way to go.
I am considering the Powerslot rotors and whether or not to get them frozen. I was thinking of only getting the slotted for the fronts and regular ones for the rear.
And how about those Hawk ceramic pads for all corners?
I don't plan on doing many track days (maybe 1 or 2 in the next few years)
Thanks !

I've got the slotted ones in the front with the hawk pads, stock in back.
I think the pads helped a little bit over stock, but I can't really say that braking is that much better than it was with all stock parts. Brake dust is minimized though, so that is a good thing.
Apparently the frozen rotors last longer, but I haven't tried them yet.
At least you got one response.. . . .![Smilie](https://www.northamericanmotoring.com/forums/images/smilies/smile.gif)
I prefer to replace rotors whenever I replace pads, so I'd probably not spend the $$$ on the frozen rotors myself. . .

Just a suggestion, do a search there is much said about brake upgrades here is one for example....

Hope it helps...

SnappyChips links are right on...
1) Are your brakes fading? If yes, then do something if no.....
2) does the dust bother you, the stock pads have a lot of nice properties going for them. But they put out more dust than a sandstorm! If you don't have fade, and the dust bothers you, go to a kevlar based pad like the EBC green. And they're easier on the rotors.
If you want mildly improved brake performance, get the metal bushings from Helix or Tyrol Sport, and some SS lines, and some pads with the stock rotors, and some better fluid.
If you want the racer look, throw all that out, and get what looks good to you, and the decision won't really be based on braking performance, but on easthetics.
If you want better braking, and less unsprung weight, look at the TCE race set up. Lighter equipment, larger rotors, and better pads with SS lines. Best of all worlds.
If you're made of money, and want to "fill your rims" get the 13" plus rotors, but that way more than our cars need, and isn't the lightest set up, so you'll be over braked, and over weight, but it sure will look impressive.
The only reason I'm running the large rotors is I found a set up used, that works on stock wheels, and it only cost $400. But the TCE/Willwood set up is what I wanted, and it just cost more....

Dr O-- I am interested in better performance, but I really want to get rid of the dust and rotor "shavings" and protect my new wheels. The main reason I am considering the frozen ones is the better life they claim to get. I have looked at those posts, but was hoping someone would post with their experience with the frozen rotors. Do they really last that much longer? I haven't seen anyone post with their opinion on the Hawk ceramic pads (thanks Partsman !) either.
Thanks

Kevlar will give you better rotor life on any type of rotor.
I haven't dug enough into the cryo treating to know if it's science, or scientific BS..... Apexers' set up is an excellent way to get less dust, better braking, and enhanced rotor life. I went to the equivalent, and didn't have fade on a track day, but I don't brakes nearly as deep as many drivers (still tightening the nut behind the wheel...
)

The "Frozen Rotors" are real, check out the website. Lots of racers swear by them. The treated rotors are harder thus, last longer (esp. with with aggressive track pads like Hawk Blues, etc.) and are less likely to warp under track conditions. On the other hand they cost about double stock rotors. For street use don't bother spending the extra $ $

Frozen vs slotted / Hawk vs Fedoro
I like the stopping power of the slotted/Ferodo combination.
I hate the incredible amount of dust (on the rears only???) and the sqwealling has me driving the car less around town. I didn't think that the noise would be that bad but it is
.
I'm going to run the stock pads around town and change to the Ferodo's only when I go to the track. That's on the front. The rear pads are coming off forever.
Addition of SS lines must happen as well, especially if you are going to track or autoX
My .02cent worth.

I have read posts about how "soft" the stock rotors are and want something that will last a bit longer and not cause so much dust on the wheels.

EBC Green pads are very rotor friendly, very low dust and stop better than the OEM pads. The "Greens" are great for everyday driving and autoX. There are better pads for track but, now comes the dust and rotor wear.

I realize it is mainly the pads, but I read a post somewhere ( can't remember where) from someone who replaced both sets of pads on 2 MINI's (his and his wifes) and the rotors on his MINI. After a fairly short period of time he notice a lot more dust on the wifes car than on his. He found out from a reliable source (MINI service I think) that the stock rotors are quite a bit softer than most replacements are.
Looks like I am going to get the Powerslots and Hawk ceramic pads all the way around. I will let you all know how they turn out.

just my 2 cents worth iwent with the stop-tech stage 2 brake kit front and rear slotted rotors the frozen also installed the brass caliper bushings.the kit was 600.00 for ft and rear rotors and pads and ss brake lines and motol brake fluid.i am very satisfied with this set up ...... no track days yet but very aggressive street driving with no fade at all....the downside it does create a lot of brake dust.......

just a couple of links for those who want to read more on cryo-treatment:
http://www.finishing.com/340/78.shtml
http://lennon.pub.csufresno.edu/~rlk16/cryo.html
and just for my final $0.02...if you read these things, they point to the creation of martensite as the desired crystalline structure. the problem with this is that martensite is only considered semi-stable as it remains below 150C. it breaks down into iron and cementite over time, with elevated temperatures. it also has a very "needle" like structure, which makes it very succeptible(sp?) to fatigue wear, this will show rather quickly if there are any thin sections on the rotors(especially if they are in the "neck" area-where the hat connects to the plates).

you should also consider what properties you are giving up: vibration damping? corrosion resistance (more carbon, means more graphite, means faster rusting)? thermal conductivity?
what trade-offs are you willing to make?
