I never had any issues at the track. Once beaten into submission they didn't make what I considered unacceptable noise on the street. Some noise, yes, but I could live with it.

They worked for me, they'll work for others, but obviously they don't work for everybody. Again, brake pad optimization is going to be *very* driver-dependent.

Dan, you've got the noisiest brakes in the paddock! Or was that the Winmax?

Those were Winmax W5s. I loved those pads *except* for the noise! Yeah, it's saying something when you're at the track with a bunch of seasoned trackhounds and heads are turning in astounded wonder at the brake noise :eyebulge: Woulda been my go-to pads except for that. Great modulation, great initial bite, high c.f., work when cold, good life. But DAMN at the noise... At the track who cares, but I tend to drive on the street with track pads all season...

If I'm unhappy with the pads the next time out, I can also get a set of 1.11s then. Otherwise, I'm willing to give up a little, for convenience. This hobby is plenty time consuming as it is.
Just IMO and my $0.02, YMMV...

If you're touching every brake caliper (as you should for a pre-track day shakedown) and bleeding fluid...the extra effort to swap a brake pad on BBK calipers shouldn't be a second thought.

While I realize DS2500s "should" be okay, they are far from ideal. Like anything else, I see it as a safety perspective running proper pads and not compromising.

If you think this is too much work, perhaps you should re-evaluate the hobby. Tough words to swallow, but just my opinion.

Maybe I got a shit set or something :iono:

I tried adjusting my braking, no dice. I just find it odd I could smear them on a damp track where I was not driving them that hard. On a hot day I could smear the rears too. I had better performance out of PMU HC800's on my stock calipers.

I thought you specifically got the PP so you could replace pads without opening the calipers?

Could be... Or actual pad compound not matching the box? I think the XP10s are painted gold IIRC?

Yeah, if you have to "adjust your braking", that ain't right...

Weird for sure. I must have run ~10+ sets over the years between the 240Z and RX-7 and never had any issues. I ran XP8s on the S2000 over the years, likewise never any problems at all with braking, and maybe a little more streetable fwiw. For XP10 and XP8 both I would prefer a bit more initial bite and slightly higher c.f. for less pedal effort required, but they never ever failed me and were IMO quite streetable even DD'ing for months on end.

It has been a few years since I ran Carbotechs, I wonder if compounds or processes have changed?

The backing plate on mine where red.



Yeah I don't know. I have spoken with plenty of people who have had good luck with the XP8's and 10's. I just could not get them to work well for me at all performance wise and mechanically.

Yes. Wanted leather/alcantara anyway, so PP at just $1200 more made sense anyway even if only for styleee points, but hate hate hate changing pads on sliding calipers. Even if I only do it 2-3 times a year...

I mighta been thinking about the Winmax being gold....

Dunno why your results were so poor, again I haven't run them in several years but when I did, on a car more than 10 seconds faster than the BRZ at Watkins Glen, no probs...

The range in experiences from people on Carbotechs is pretty broad IMO.
