What Racing Pad do you suggest....
Had my first event yesterday with PFC01 pads all around. Not sure if I like these pads. I don't think they were bedded in well enough at first, as the wheel would shake if I didn't brake in a very straight line. Also, it looked like I had previous pad residue on my rotors. Either way, things got better after my 2nd session.
They really bite, but seem VERY difficult to modulate. There's very little range from no brake to near lockup! Dunno if this is how good pads work that are brand new or not? It made it nearly impossible for me to heel/toe; had to relearn how with the different pedal range, but probably to be expected.
Man do these things squeal now! I knew they'd squeal on the street when I drove to/from events, but surprised how much they squeal on the track!
Can anyone speak to the modulation issue? I obivously had to relearn all my braking zones for the track, as I was braking too early and thus scrubbing too much speed. I believe my overall times from my last trip to Putnam didn't improve as I was really having to learn the brakes - and my group was pretty crowded.

3 days on track now with them, including 1 day in the rain. Overall I'm really liking the pads. The on/off modulation issue I didn't like has gone away. I'm assuming it was mostly attributed to a new 7/16" pad and just my personal learning curve. I was able to heel/toe last time out continually and brake deep into corners with confidence repeatedly.
I might have gotten these too hot last time out though. I did not experience fade, but when I would go out for my later sessions, I had to pump the brake pedal back up to 'firm up' the pedal. Reminded me of the feeling you get after bleeding your brakes and you have to 'firm up' the pedal. Brake fluid level was spot on, so there were no leaks.
My calipers have darkened a bit, but not like I expected. Kinda sad really....lol.
My setup:
PFC01's all around, 255/40-17 RA1's, Motul. Stock rotors; no cooling ducts; no front undertray.

Yeah, I'd add some cooling to your setup. I was boiing fluid every session until I added brake ducts... As for the ABS, you can just pull the 60a fuse under the hood and you'll be fine. I've been running without it for most of the season after I melted through both front abs sensor harnesses.
I've had the undertray off of both my Evo's. After I put on the exhaust I've just never put it back on. Suppose I could cut it a bit for the new intercooler and put it back on. Possible 'off-season' update.
I would think the Evo would be a bit more aerodynamic with it on too.

Trimmed the dust shield - melted the harnesses. Removed the dust shields, repaired the harnesses, tied them back to the hub, added Forge duct kit - melted again (not as bad though!). Now they're covered in heat wrap, hopefully that does the trick. If not, I'll just leave the abs non-functional. Taught me better pedal modulation anyways...
"Where exactly are the sensors, I'm thinking it'd be a good idea to wrap these to help prevent melting? If so, wrap with what? I think Kyle said he's melted these too."
I will wrap them in heat wrap but a good zip tie job to the lower control arm does the trick. Also, for the later Evos with the active center diffs, when you melt those sensors it also knocks out the center diff controller (ask Me how I know) The result is your center diff remains in full lock, not unlocking when you turn as it should. This is very good for sliding the rear of the car around like a pro rally driver in the dirt, but if you push it in this condition on the pavement, you may end up with a broken rear diff (ask Me how I know). Sell the Motul back to the French and get the SRF and cooling kit, I like My AMS kit personally.

Another PFC01 Update
Figured I'd update everyone on my PFC01's.

Took the pads off the other night to put my street pads back on. I've used about 3/32" of pad on the fronts. Have no idea if that's normal, or how to guage pad life at this point.
I have 2 full warm track days (3 full tanks of gas total) on these, 1 rainy day (about 3/4 tank gas) and street driving. I'd wager 220 miles on-track in dry; 100 miles on track wet (reduced braking obiously) and 1000 street miles.
Update time.

Are the street miles mostly highway to get to the track (i.e., little brake usage)?
I've used Pagid RS14s up front for a long time and just put Ferodo DS2500's in the back. I really like the RS14s but they dust a lot (and by a lot I mean I'll wash the wheels, and an hour later they need to be washed again) and they aren't quiet all the time. They mostly only squeal just after they go through a car wash though, or low-speed stop and go traffic. And for those of you who think running the 2nd most aggressive race pad Pagid makes on the street is dumb...well you don't drive like I do...I've overheated hawk blues on the street with RBF600 fluid and I'm not kidding....but the RS14's I can mash all day long on the street, track, auto-x, whatever and they don't fade much if at all...
