ABS with Carbotechs
 

So I recently installed Carbotech XP10 front and XP8 rear pads and let me just say - insane. Night and day difference from the Racing Brake pads I was using, it's easy to eat dash now!

One thing I was wondering from the other CT users out there, with hard brake application is it normal for you to get ABS engaging? I would almost never have ABS kick in with my last pads on dry pavement, no matter how hard I pressed the brakes. With these though, even on dry roads I'm getting ABS with 80% or higher application, is it because they are biting so much harder they are locking the tires?

Not a big issue either way, just curious. The squealing brakes is pretty funny as well, not something that bothers me so I just chuckle when I roll to a stop and people look over thinking 'damn dude change your pads already!'

I know "ice mode" can happen much easier but since you used 10/8 I don't think it happens much. Just be careful!

Ps love the squealing comment!

Yes be careful

Yes, these race pads will have much higher bite, particularly with street tires on the street. When you get then up to track temps you can squeeze on them real well

Thanks guys. I'm always careful ;) I didn't think ice mode was something I have to worry about with just the 10/8 combo, maybe I'm mistaken? I seemed to recall it was happening to people that had added a BBK or were using XP12's and up?

No there is too much bite from the 10. The front pads have more impact than the rear.

Gotcha. Well I do have XP8's on hand for the front in case the 10's prove too much

You DDing them?

You bet!

Not suggested. They are strictly worse than OEM for street duty

Lol well having had oem brake pads on there, I can assure you these stop a lot faster even when cold. It's also not suggested to double the PSL on a regular basis but that generally happens too ;)

I've heard that before, but other than dust or noise I'm not sure why you wouldn't want these on the street. Good cold bite and massive warm/hot bite.

Edit: Don't get me wrong, I appreciate advice. Just my definition of street duty and the general definition is a good distance apart. When you live your life 1/4 mile at a time, are you really still street driving? :ugh2::p

Nice. I REALLY don't feel like swapping in and out. I'll probably be fine.

Oh ya, I think you'll be good. Like I said, suuuuuper squeaky on the street lol, but it's a small price to pay for slowing the rotation of the earth every time you hammer on the center pedal.

With the Hard Brakes titanium backing plates they don't squeal on the street near as much.

Oh ya? Hmm might be worth the investment

Which ones do you suggest, the .5 or the 1mm? Also is fitment like stock, with tabs to keep it nice and secure on the pad?

How does something on the back change the squeal on the front? Also, with such a little plate has anyone actually done independent testing they reduce caliper heat soak?

They do have tabs, and personally I'd suggest the thinner one so you don't have issues trying to squish the plate + a new pad into there (or have to try to shave down your pads),

A lot of the squeal really isn't from the mating surface, even though it sounds like it. They did objectively reduce heat back when I first tried them (sport calipers + CT pads). I use them now on the front of my Stillen kit, too (different shape).

Cool thanks! Any idea on the thickness of the stock shims?

0.5mm shims are on the way, thanks for the suggestion DR_

I had the XP 10's/ 8's. The 8's on the rear were aggressive at times on the track. I had 6 piston AP BBK on front and Akeobono (if that's the right spelling) on the rear. So not sure if the setup/ bias is off but it would be safer with less aggressive pads.

Off topic but in response to the earlier comment, I also would recommend something else for dd. The bobcats are great, if a little pricey. Much less dust and easier on rotors

SPOHN, did you have the akebono 4 pots on the rear? I can see them being a bit overpowered for the rear in that scenario. And are you saying you encountered ice mode, or just that it was a bit much?

Aside from if I could expect ice mode issues, I don't see a compelling reason not to use these on the street TBH.

He said he had them on the rear.

What I want to know is what did he mean by to aggressive. Like do a 10/6 or 8/8 or 8/6?

He said akebono rear not if they were the two pot stock rear or if he put the stock fronts on there.

Pretty sure they were the stock two pot. 10/8 worked well for me on street tires.

Yeah 10/8 seems to be a pretty good setup with the stock calipers and street tires.

Can someone give me a good reason not to use them on street? Everyone is kinda like 'not a good idea'. I know they cost more. I know they dust more and are louder, I know they will wear quickly. They will eat rotors faster. They need heat to work really well. None of those bother me and I expected all of them.

Aside from all that, is there another reason?

Edit: with all the people telling me not to do it, my original post didn't even get answered lol

O god that'd be impossible. I know he didn't though. That'd be a crazy setup.

I googled them a lot one time and always found people say no but no reasons why. Even found some running in winter states.

Not really. Some true race pads are dangerous on the street, in that they have terrible grip when they're cold (and no matter how "aggressive" you drive on the street, you're unlikely to get pads track-hot on the street - unless you're planning to slam on your brakes full force every 10-15 seconds for 10-30+ minutes straight). That's probably the general reason people advise against it.

However the Carbotechs (at least, the lower-end XPs like we're discussing here) seem to grip just fine cold, they just make a lot of dust and noise and everything else you mentioned. Most people get pretty tired of it pretty quickly on a street car. Every time you pull up to an intersection to stop, everyone around you is going to by saying "WTF is wrong with that car, he should go get his brakes checked before they fall apart" :)

Ya exactly. Well unless someone tells me 'you WILL get ice mode and your brakes will fail and you will crash and die' I'm gonna be doing it. Don't get me wrong... They will see track use I didn't get them ONLY for street. But 95% of their use will be DD

It's very unlikely that you will trigger ice mode on the street. At least I hope you're not driving in such a manner :)

I agree but I hear that with like motogp pads and carbon ceramic brakes. I think steel with aggressive pads should be ok. I'll take the risk too when I get ready for them here real soon. But aventadors have carbon rotors though :confused:

You'll be fine. :tup:

Hmmm? Sounds like a certain black 370 from Houston! :icon17:

Lol, I seriously can't overstate how loud they are.. my buddy was riding with me the other day, and he rolled up his window, said he was too embarrassed. :icon17:
Everyone stares, I think they are looking around thinking there is a city bus they can't see. Doesn't bother me though!
