Which carbotech pad compound?

[Lunares]

Heard good things about the carbotech compounds for track use, but which ones are people running?

Choosing the Correct Compound – Carbotech

Lots of options in the XP family!

Any big issues with street driving XP compound? The bedding procedure they recommend looks intense.

I’m running XP10, braking on street works pretty OK.

The biggest downside to the Carbotechs IMO is how incredibly, obnoxiously loud and squeaky they are. None of my other track pads make noise - just the Carbotechs. I would recommend XP20's up front and 12's in the back if you are OK with swapping the pads out before and after events. Functionally, all track pads have been fine on the street for me, regen does most of the work on the street anyway.

I have been running XT910 since was mostly autocross focused, but geared the same complaints as you on the XT970 so was looking at carbotech. What's the current recommendation if you arent willing to swap pads between events?

If you don't want to swap pads between events, look at Raybestos. The ST43 is a great pad for use with 200TW. If running R-Comp or Slicks put ST45's on the front.

I'm runing RE71Rs, looking at Nanking AR1s in the future (eventually Hoosiers).

What's the cost delta between these and Carbotechs?

Similar, I bought rear ST-43's for $250. I imagine the front's are slightly more expensive but not entirely sure. They haven't listed them on their website yet, but I ordered from KNS Brakes (KNS Brakes).

Anyone else have comments on the carbotechs?

Waiting on KNS to get back to me on Raybestos

Haven't used carbotechs in several years on my s2000 but I remember the brake dust used to cake on the finish of the rims. Are you guys noticing any of that? Just did my first track day with the M3P w/PUP and the stock pads faded after 2 laps smh

My Mustang weighs about the same as the Model 3. On the track I used XP20 /XP12 F/R on the Mustang. On the street I used 1521's. The nice thing with the Carbotechs is you can use the same rotor with multiple compounds which means you can change just the pads between track and street which is much easier than changing rotors too. I am going to start with the same Carbotech compounds on the Model 3.

I never had squealing issues with the 1521's on the street. The XP20 or XP12 would likely squeal.

How's the rotor wear with ST43?

Here's a good chart - I had to ditch the Model S rotors not for wear (they barely had a ring) but due to cracking, so pretty good!

All track pads are going to be pretty dusty, I do think the Carbotechs create a bit more dust than the Raybestos but either way you are going to have to clean your wheels often!

Interestingthat ST47 is so aggressive yet very low on rotor wear by that chart. any idea why?

Honestly, I don't understand it well enough to say. You could try asking Raybestos or KNS Brakes (a distributor).

Unplugged’s street/track pads were fine at Road America entering ~140mph 3 times in a lap.

If you want to go as fast as possible in a qualifying/time attack style, you won’t build a ton of heat if you’re only doing 1 hot lap in a row and resource managing effectively.

If you want to burn the battery to the ground and chase dentist Freds for whole sessions, it might be more important, but largely I haven’t found temps being the shortfall in braking. I upgraded to 6-pot brembos for feel/modulation.

I run XP12 Front and XP10 Rear on my ICE Track Car....but it's not nearly as heavy as a Model 3. Love both CarboTech and GLoc...know the folks at both companies and am glad to support a pair of NC companies. Anyway....like others have said, for a car this heavy...the XP20/XP12 combo is probably good if you're turning pretty quick laps. If you're turning exceptional laps,the XP24 up front will certainly whoa you down effectively. The RP2 is more for endurance....I ran those back in the day once. They're equivalent to an XP12....

KNS reporting that Raybestos has no ETA on making more model 3apds due to material issues. Might end up with carbotech after all but going to try and hold out!

Damn, that stinks. Mine have worked great thus far. I wonder what the issue is.

Nothing wrong with the material, just covid shortage onsupply
