Never done an 'official' review so here it goes.

Brake Pad Manufacturer (F/R): Carbotech
Caliper (F/R): OE
Rotor Size (F/R - IE OEM or specify): OE
Compound (F/R): XP10
Tires: ZIISS 215-45-17

Feedback:
Great track pad to replace OE after I roasted them on my second track day. Driving home with soft squishy brake pedal with a pad that felt like it had the grip of a chalkboard eraser was sketchy so I jumped straight to XP10's and couldn't be happier. I did 3x track days on them (2x Laguna Seca, 1x Thill 5-mile) and I won't pretend to be a quick driver, at Laguna Seca I pounded out mid 1:5X times (quickest ~1:54, consistently 1:54-1:57 iirc) with clear track ahead of me with a mostly stock car (ZIISS were the biggest performance upgrade). Scores are below but I couldn't have asked for more on track, they did what I asked and let me focus on having good lines and carrying good speed.

I tried to DD them and as mentioned elsewhere they were too loud for me. They were fine after a track day and autocross, but I believe as the transfer layer wore off they got loud, and I wasn't willing to do a 2am bed-in procedure once or twice a month to avoid changing pads.

Cold bit is solid, they're perfectly fine to DD on except for the noise. I also autocrossed them and I felt like they performed flawlessly. Worth noting that the guys who made Carbotech started Gloc and offer a competitive offering that seems identical. I still have these at ~90% life and will keep them for whenever I take my car to the track and swap them in without hesitation.

Scores:
Dusting (1=high-10=low): 4
Cold bite (1=low-10=high): 9
Hot bite (1=low-10=high): 9
Modulation (1=low-10=high): 9
Noise (1=extremely loud-10=quiet): 10 (bedded in, on track) 2 (transfer layer worn off)
Pad Lifespan (1=short-10=long): 10 (track newb, still look at 90% after 3x days)
Does the brake dust with this combination damage the wheels/paint if not cleaned immediately? N
Brake ducts: N

Feedback:
I got these to replace the faded OE pads and use as an autocross pad. As an OE replacement they're a solid reliable DD-able pad that should take some light abuse without being shaken (like a casual backroads run), I wouldn't have any problem recommending them for that purpose.

However I have felt fade on them while autocrossing, on a very large fast course requiring a few hard stops they start to lose bite. We're talking a few 3-2 heel toe 70-30 downshifts during a run. Of course they cool down after the run and are ready for the next run no problem, but that fade going into a final hairpin or turnaround can be killer. To be clear, the pedal feels fine it's just there's not enough stopping power so you press harder and harder to get the slow to happen, definitely overheated pads in that scenario.

If the autocrosses are small (or you're just starting out, or you're on non-sticky tires) I wouldn't worry about beating on these pads, but you couldn't pay me to go on track with them, no way they'd last more than a session if you're pushing it. I'll likely be replacing them with Gloc R6's for a DD/autox pad and the XP10's are in a box waiting for the day I hit the track again. I'd probably try Stoptech pads if I wanted a DD-only pad.

Edit: my opinion of these has improved, I think I was driving like an idiot when I faded them and good modulation, perfectly good for all but the most extreme autox courses and last of the late brakers
Edit2: as they aged I grew to dislike them, they were spongy and I had one codriver commented that they were his least favorite part about my car, and that was on $86 Firestones, I liked the long pedal to play with brake pressure but you have to get into them pretty far to get good stopping power, I've switched to Ferodo DS2500 which are performing better.
