Which pads for road course???

[ArizonaGT]

I swear by PF01s front / PF97s rear. I've run the Hawk DTC pads and they just disintegrate even with cooling. PFs last longer, don't eat the rotors, and have a higher max operating temp, not to mention stop extremely well.

May have to try those... how many hours can you get out of a set up front? What's your vehicle weight?

Typically about 4 weekends or 10 hours on the fronts, 7-8 weekends or more on the rears. Car is 3450-3500 race weight depending on organization, 3" front brake ducting, no rear ducting.

The OP is using the stock 2 piston caliper's that came with his 05 GT. (12.4" drilled + slotted rotopro's ).... + HP+ pads. And has front brake ducts + hoses. You can only do so much with the oem 2 piston front rotor's + oem 12.4" size rotor's.

 

[ArizonaGT]

Well then PFCs arent an option.

 

[cop on my back]

I have gone with Carbotech, XP20 in front and XP10 in rear. This was suggested from the tech guy with Carbotech after he asked some specific questions. We will see how it goes in July when I hit the track.

Ordered AX6 and XP12/10 this morning. I will report back in a few weeks.

Happy guy here. Added 3" cooling ducts and the aforementioned pads along with new Centric rotors. The AX6s are great on the street, much better than the hawks I was running. Quieter and better intial bite. I have not autocrossed on them yet but I expect them to be just fine.

We did a 2 day track day over the weekend. 4 run groups and 20 minute sessions. So the car ran 20 minutes and was off 20 and then back out for another 20 and so on with an hour for lunch. The only time I had any fade was when the combined the two middle groups and we ran back to back on the second day, towards the end of the second session in a row the 12s started to fade we brought it in and let it cool down. Gave it 20 minutes off and we were right back out there and everything was fine. The 12s are about done, I would consider one more, one driver, track day at most, but since we essentially put 120 hard laps, not counting warm up/cool down, I feel pretty good about them. The 10s look about new really.

I drove home on the XPs because lazy and tired and wanted to try it. It should have been all interstate driving but apparently all of Illinois was in Michigan for the weekend so lots of stop and go when we should have been doing 80. They are fine on the street but I didn't really like the way they felt, stopped fine, just wasn't great.

Is there a CoF and temperature range chart available for the Carbotech line? I would like to see it if anyone has access to this information. I might try XP16s up front but I would like to see what I am gaining or losing by doing that.

Front pad shopping time...Currently running DTC-60 f/r (brembo fronts). Not terribly impressed. While the stock abs module isn't helping, I find it too easy to get into ABS even on street rubber. Brake fade/mushy pedal with Brake cooling/good fluid while driving 7-8/10ths

1. Need something that would be an appropriate match for the barely worn DTC-60 rears.
2. Would like to try something other than Carbowear or Hawk.
3. I'm not competing much lately, so longevity is near top of list.

Side note: Anyone know if there are any differences in STOCK GT abs module programming throughout the 05-09 years?

Carbowear, that's funny.

I keep hearing great things about the Raybestos ST line.

Temperature range I can find . . . couple of sets, actually. I've been interested in this topic because I'd discovered what condition the XP8's I've been running were in after 5 track days and around 5000 miles of street driving. The good news is that wear was under 0.17" from new, and that they worked just fine even in the winter. The first couple of stops on the morning after a track day were a bit soft, however.

But regardless of what Carbotech advertises, I shouldn't really give them any "perfect for HPDE use" rating beyond paced laps.

Boldface and color mine

Carbotech XP8™ (1108™)
A high torque brake compound with a wide operating temperature range (200°F-1350°F+). Carbotech XP8™ is the first of our racing compounds. Outstanding initial bite at race temperatures, high coefficient of friction, excellent modulation and release characteristics. Extremely high fade resistance, very rotor friendly with 100% non-corrosive dust. Excellent as a front brake pad for lighter ITA, ITB, ITC, SRF, H4, H5, and other cars that weigh less than 2,400lbs. Perfect for novice, intermediate and advanced track day (HPDE) use with any tire, and can still be driven safely to and from the track. There are several vehicles that use XP8™ on the street, autocross, and at track day (HPDE) events. Carbotech does NOT recommended XP8™ as a daily driven street pad due to elevated levels of dust and noise. XP8™ is also a great rear brake pad for almost any race car (Spec Miata-T1/T2/CMC). XP8™ is a great compound on the front & rear of most open wheel and sports racers.
Carbotech™ XP10™ (1110™)
When Carbotech unleashed the XP10™ to the general public, and it was an instant success, gathering multiple regional, divisional, and national championships. The XP10™ is a very high initial bite friction material, with a coefficient of friction and rotor friendliness unmatched in the industry. Fade resistance is in excess of 1650°F. Due to the high level of friction and bite, this material is recommended for cars weighing around 2,000lbs or more, not including formula cars and cars with brake bias bars weighing less than 2,000lbs. This is the preferred compound for the front of Spec Miata racers, SSC,SSB, T3, SRF, ITS, ITE, H1,H2, H3, H4, 944 Cup, ST, GS, Factory Five Cobra’s and many more Grand-Am/ALMS/SCCA/NASA classes. XP10™ is also ideal for advanced/instructor level HPDE drivers. XP10™ still maintains the highly praised release and excellent modulation, rotor friendliness, and 100% non-corrosive dust that have made all Carbotech compounds so successful. XP10™ is not recommended as a daily-driven street pad due to possible elevated levels of dust and noise.
Carbotech™ XP12™ (1112™)
The latest iteration of the highly successful XP™ series of compounds with an extremely high initial bite, torque and fade resistance than compound XP10™. XP12™ is a world leading friction compound that is unmatched as a Ceramic racing compound, with a temperature range of 250°F to 2000°F+. The XP12™ still has that excellent Carbotech release and modulation that has made all other Carbotech compounds so successful. The XP12™ is the most rotor aggressive compound Carbotech offers, but compared to the competition the XP12™ is still very rotor friendly and contains 100% non-corrosive dust. XP12™ is recommended only for expert/very advanced drivers. XP12™ is found to be most affective on race cars weighing 2,400lbs or more using R-Compound tires; or street cars weighing 3,200lbs or more for track use only. Ideal for LMP1, LMP2, DP, T1, T2, T3, H1, H2, GT1, GT2, GT3, TC, GT, ST, GS, MX-5 Cup, etc… XP12™ is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise.
Carbotech™ XP16™ (1601™)
The second compound to be released this year from Carbotech. It is a step up from the highly successful XP12 compound. The XP16™ leads the highly touted XP™ series line of compounds from Carbotech. With an extremely, and we mean extremely high initial bite, torque and fade resistance than compound XP12™. XP16™ is a world leading friction compound that is unmatched as a Ceramic racing compound, with a temperature range of 250°F to 2000°F+. Carbotech XP16™ still has outstanding release and modulation that has made all other Carbotech compounds so successful. The XP16™ is the most rotor aggressive compound Carbotech makes, but compared to it's competition the XP16™ is still very rotor friendly and contains 100% non-corrosive dust. XP16™ is recommended only for expert/very advanced drivers. XP16™ is found to be most affective on race cars weighing 3,000lbs or more using R-Compound tires only. Ideal for sprint use only in classes such as T1, T2, H1, GT1, GT2, GT3, GT, GS, DP, P1, P2, etc… Not recommended for use as a daily driven street pad due to possible elevated levels of dust and noise.

Hard to believe that these things never faded on me other than some green fade on their first track day.

Decided to give performance friction a try. Went with the tech line's recommendation of their 08 compound for the fronts on a car that gets driven to the track. He also stated he the 08 compound would be easier on the rotor than the 01, similar torque at temp, longevity, better wear, less noisy/dusty(not that's a concern really but welcome), don't require much bedding, and long pad life. **They freakin better since they are probably the most expensive set I've purchased to date. Hope to try them out at Gingerman next weekend.

My current setup for the past couple of years has been Ferodo DS1-11 race/enduro pads up front with 2500's (street/track) in the rear. Great balance, easy to modulate, impressive longevity (because enduro pad) with minimum fade.
If your looking for something to last awhile (4 events in and still have aprox. 40% pad life left) these might be worth trying.
