I am going to be racing in the upcoming 12 hour enduro, The Devil in the Dark. I will need to get new brake pads and rotors on the car prior to the race. I have heard about Hawk Blues and Carbotech's, which are best and where can I get them the cheapest?
Also is there a big difference between the OEM Mazdaspeed rotors and the after markets that go for much cheaper? Where should I source these as well?

NAPA had a pretty good rotor for 19.00 Safe Racer has a pretty good deal on the Carbotech's

Will the carbotech's that saferacer sells pass SSM regs? The pictures of them show they are slotted rotors.

He meant NAPA blank rotors and Carbotech pads.

Hawk Blues are superceded by the DTC-60 front and DTC-30 rear.

Thank you, that is what I was trying to say.

Paul can you expand on that, I love my blues, are you saying they are going to phase them out or just that this is the new pad that is better than the Blues?

They still make Blues and sell a lot of them, but the newer compound is the DTC compound. I raced a friends car last weekend at Homestead with Blues and had a hard time trail braking and couldn't modulate my brakes very well as compared to my car with the DTC pads. Whenever I hear someone say that they hate Hawk pads or switched to Carbotech or Cobalt or....they have been talking about the Blues and not the newer DTC compounds. I know that the OPM cars were running the DTC pads. I am using the HT-10 compound on the rears as my DTC-30's wore down a little quicker.

Frank,

I would suggest staying away from the napa cheapy rotor, I just put a set on for my last race and had trouble stopping with them, almost like I was on backing plates. I put on my old rotors (carbotech oem replacements) and the problem went away. So if carbotech is your choice, save yourself some money and go with the carbotech xp10/xp8 combo with the carbotech oem replacement rotors. Can't speak much for hawks, haven't used them in 3 years.

Shoot me a message about Carbotech if you're interested in that route.

I've had issues with the Carbotechs gumming up rotors with pad deposit. Found an alternative that works well for me and last longer. I've heard some good things about the Hawk DTCs but haven't tried them. For rotors I go with NAPA premiums or ultimates depending on what they have on hand.

John, My first set of NAPA rotors I put 2000 track miles on them using Hawk Blues, and they still look good, I just ordered another set, because I wanted to try the Carbotech's and I wanted to start with a fresh rotor. The first set of rotors were made in Canada, this last set was made in China. I guess I will find out if that is the difference you were talking about.

One of my last cheepy rotors (Rock auto, I think $11 before shipping?) had some run-out right out of the box... felt just liked a year-end abused and warped rotor on the first lap!

I'll pay the few extra bucks for the more premium rotors.


Cobalt Friction are another good option - and if you need to do a swap in the middle of the race, don't require bed-in.

Contact me if you're interested in Cobalts.

I've heard positive things about the Hawk DTC-30's. A guy I know in my paddock runs them at all 4 corners. I am now running the Blues and HT's, but my next set will be the DTC compound.

+1 on the NAPA blank rotor.

Raybestos ST43 front and rear from Porterfield Brakes (949) 548-4470. Talk to Tim Gray and tell him Rob Gibson from RJ Racing sent you.

Lasted for the 25 Hours of Thunderhill with about 30% pad left on the fronts and the rears looked barely used. Better initial bite than Carbotechs but still good modulation. And they're cheaper.

+1 on the ST43's... I used them on my ITC car for years, awesome pad's! When I converted to ITB, I went back and tried the XP's... all I can say is I can't afford a set of pad's per weekend.

I've only rand the SM once, on a set of Blues. It was all or nothing with them... which forced me to brake a bit later than I may have otherwise chosen to do.

Holy crap! How many sessions are you guys getting out of a set of brakes or rotors?

Muda - I trust you had those "slotted" ones on for a few more than a single race weekend...

Went with Carbotechs myself (10's on front, 8's rear) and a nice set of AutoZone specials for rotors. Did that last summer (July/August), managed to attend 8 days of HPDE's for 2009 and then a pair of SCCA schools this year with a single race and I'm still able to see the notch in the front pads!

Am I just not hitting the brakes hard enough (cuz I've locked things up a couple of times already this year at NHMS) or am I just "good"? [Razz]

I'll go with good thankyouverymuch! [duck]

Anyone using an IR gun to take rotor temps? If I had rotors cracking like the photo I would definitely take some temps and discuss the compounds with the brake pad manufacturer. I am using NAPA premium with my DTC pads and have no cracks at all after a year.

We are talking NAPA 4886213 front rotors and 4886214 rear rotors.
I just picked mine up from NAPA today for $67.76 for all (4) rotor is my kind of cheap racing.
About pads I am running DTC-30 front and HT-10 rear on my 240SX and they seem to be great. I installed them after telling HAWK I was using the car at track days for fun.
I was going to use BLUE's but now I am still deciding and this thread is a great help.

Maybe a Summit Point thing. I have had some look like that too. They were the Carbotech rotors and XP-10 pads.

As far as 8 HDPE days and two schools and still seeing the wear notch... [Eek!]

I am getting between 2 and 3 race weekends out of a set of pads, depending on the qual/race format.

Keeping with rotor theme.
I bought one set of Rotors from Kragen and Napa for my 240SX and found the Kragen rotor thinner on one face than the other. I will try to post a picture tonight so you can see what I mean. I will stay away from cheap Kragen rotors.

I order mine from http://www.Porterfield-Brakes.com as they give SCCA members a discount. You may have to email them to get pricing on the DTC's as they are not on the website.
The other place is SummitRacing.

Well, just learned something this weekend at my second novice race (got signed off - YAY!).

The 1.6 NA's have significantly smaller rotors than the 1.8 NA's. I did not know that.

And those guys who are noting cracked rotors after a fairly small number of weekends I see are 90, 91...93...and they could also experience a less than stellar performance from the aftermarket (China sourced) rotors.

Gotta say, these AutoZone specials and the Carbotech's have been fantastic! Flipped my pads before qualifying on Sunday and hope to get at least 1 if not 2 more weekends out of them ; presuming practice, qualify, race per "weekend".

And to Monsieur Alan: touché
