Will Hawk Blues chew up my rotors?
I put some Hawk racing Blues on my car Sunday. I bedded them in on a long straight I know of in an industrial park that used to be a drag area long before I was born. What a difference!! I am doing my first DE this year on Thursday. <img src="graemlins/jumper.gif" border="0" alt="[jumper]" /> Did my first 3 ever last year. Will these chew up my rotors and how long will the rotors last?

I don't know about the 944 rotors, but I have friends with SE-Rs who have ruined rotors on the drive home from DEs when they didn't change back to their street pads for the drive home. They thought, "how bad could it be?"
The blues want a lot of heat in them. Once they get heat in them, they do not chew the rotors. We installed some blues on our Sentra SE-R ITS race car for the 6 hour enduro at Texas World Speedway last November. They even chewed up the rotors there because there is not enough heavy braking to keep them hot. We only ran for 2 hours because we lost a brake line and spent the next 4 hours kluging together and OEM one from another application. I think if we had run them the entire 6 hours the rotors would have been completely shot
I would not recommend them on the street. However, if you only use them at the track, they seem to not be terribly hard on rotors if you have enough heavy braking at whatever track you are running to keep them hot.

I seem to be brining up an old subject, but...
Geo You said the Hawk Blues are great pads, but can eat rotors when cold. I am looking for an upgrade pad for 944-spec car. This week end I found that my Metal Masters just gave out. Plenty of pad left, but I think they got over heated at the last race and just had no slopping power any more. Really got spooky a couple times. I replaced them with fresh Ferodo street pads and was fine for the rest of the weekend. A 944 Turbo driver told me about Hawk Blues. Said he loved them.
Now.. is a 2450 lbs 150hp car with 3" brake ducts too light to get enough heat in to hawk blues to prevent them from "eating rotors"?
What pad are you looking at for your ITS Car?
Thanks

I have an interesting "phase shift" for your thinking.
Given the cost of the components, maybe you want to ask, "are my rotors hard on Hawk Blue pads".
I use Hawk blues on my 924S race car which has stock brakes fitted with Cool Brake ducts. The pads are the best I have used including Cool Carbon, PFC, Metal Master etc.
The thing is, the pads cost me around $250 CDN ($150 US) per axle and rotors cost me $50 CDN ($30 US) or $100 CDN per axle. This makes the cost of rotors 40% the cost of pads. I consider rotors to be consumable, just like oil, gas or whatever, and I put a new set on every time I change pads which is usually once per year on the front and once per four years on the rear (I do about 8 events per year). Considering that cost of the pads, the rotors are a minor investment.

Me too... as reported earlier, I've had no problem with MM's and street tires, but as soon as I swapped to race tires, the MM's couldn't hang. Gonna try the KFP Carbon-Kevlar next - at Jason's request.
Good Luck!

M758,
A ex-Firehawk racer had recommended the Hawk Pads about 6 track days earlier in the year, but for some reason it was going to take a little while to get them. So I went with the Paragon Carbon Kevlar (gold?) You WILL feel the difference.
I have run 4 race days and a 2 day school at PIR with-out any noticable wear although keep in mind some drivers : ) may trail brake a little more than myself so who knows re: the wear.

Thanks for the info Paul.. I think I know that ex-Firehawk racer 
I know the KFP pads will be an upgrade over my current pads. Till this point never thought it would be needed. However going into the tower turn with full brakes and still not stopping at the right angle for a major T-bone job on one of your fellow drivers make you think. Thankfully I was able to drop the car in second gear and broke the back end lose to get her rotated or else..
The pedal never faded it was just the pads did not grip anymore.
Anyway here is what i am thinking for RACE Applications with the occasional fun Autocross
Metal Master = adequate with proper cooling
KFP = better
Hawk Blue = Better Still??
Pagid Known Good, but too much $$$$$$$$

In all likelihood I'll try the Hawk Blues. They come so highly recommended. As for weight and hp, the 944 is right in the same category as the SE-R and they have pretty equal braking power, so I'd guess the SE-R is a good enough model to know what to expect with the 944. (wow, what a run-on sentance)
Now, that (all that) said, there are many more options for the 944 than the SE-R so I cannot tell you if there are any offerings that will work better (for instance I've read good things about Pagid). But, Hawk Blues seem to be rather universally well liked.
