I have XR-2 and GTS still work for me. I turn my front rotor a little blue on the edge so I want to go up to XR-1 and XR-4 with some duct work.

 

Bringing this thread back to life as well I had similar experience with the XR2's. Great bite and my fluid boiled before the pads faded. But they just don't last very long I got one day at buttonwillow and like 3000 street miles out of them and they get cooked on to wheels I'm on the search for a different set of pads.

 

^^^ different car, but same result on my end. I had xr3 (front) and xr5 (rear) on my Miata, and they aren't meant for those who do street driving. I did the same, 1 day at BW, and the next week just daily'n the car around town. Then later on noticed a horrible mechanical noise from them and the front pads were done, rotors eat'n up, but the rears were fine. Dust from the XR3's are bad for the wheels. Don't let them cook on there for too long or it'll be etched in with the wheel finish .

But, even when they were nearing the backing plates they stopped like new, so they sure do last till the end quite literally. Good stuff for more dedicated track cars. CT's are much more forgiving, and work great for my application, so nothing against the XR lineup.

 

I run the XR3/XR5 combo. I did a track day in December at BW then proceed to go on a road trip right afterwards. I put 2k+ miles on them before I finally got home to swap out the pads and rotors. I only put a few mm's of wear on them and my wheels had zero signs of etching.

 

Well, using these pads on the street is never recomended by us at all. Any time you use a racing pad on the street for long periods, when they are not at the proper opperating tempatures the rotors and pads life will suffer. I have XR2 /XR5 on both our time attack cars. we get 3 track weekends( 6 days) out of them at most tracks. on some tracks that are real heavy on brakes, it can be lesser. Of course driving styles vary, so pad wear can sometimes be hard to gauge user to user.

 

Have you experienced the pad cooking itself onto wheels ?

 

Really interesting replies here. I usually get at least 5 days out of my xr2/xr5 setup on stock wheels with nt01s. This is actually my 3rd set of this setup and I've never had any adverse effects. My current set has about 3-4 track days and about 5k street miles on them and they still look pretty good. Wheels are also fine but I usually wash them within a week of getting home from the track.

 

I have a extra set that I run R888. I usually put wax on the rim inside & outside before track day. Then I leave them on. After track day I wash my rim and take the wax off.

Good like new.

I run XR-2 & GTS. My GTS replacement will be either XR-4 or XR-5.

 

Nope, no problems on either car. we just make sure we wash down thewheels after a track day. we normally do that anyway

 

The problem you guys are asking about will only happen if your running at race speeds in the rain. For one reason or another when you combine water & high temps (to the point where the water evaporates off the wheel) the compound will bind to the finish. It can be removed but takes elbow geese.

BTW this is not a singular problem....Carbotech's products do the exact same thing as well as a few other manufactures. The rear wheel on the S2000 gets it the worst cause the solid disk transfers much more heat to the wheel which effectively bakes it on. If you know its going to rain....just wipe the wheels down with oil, WD-40, or wax and you won't have a problem.

Never street drive with these pads. All your doing is throwing your money away. I got 7 days out of a set of XR1s / XR3 ands still had more than 70% life on them. If your street driving.......your doing it wrong
If XR2 is only lasting a few days jump up to XR1 (asl ong as your on race tires that is).
