Brake pad swap questions

For those of you who track a lot...

I recently got pagid's as i get more into tracking my car. I switched out the pads myself prior to the track day. When i take off from a slow start, i hear a loud popping sound from the brakes. From research, it seems this is the brake pad slapping against the caliper, root cause potentially from not greasing the guide pins and/or brake pads?

So i have a couple of questions in regards to this
1) has anyone else experienced this before? How did you fix it?
2) what brand/type of grease do you use for the pads and for the guide pins?
3) on the pads, i assume you are greasing the back of the pad, not where the pad contacts the rotor (yes i know stupid question of the day but want to do this right)

Thanks in advance!

1) Completely normal with the Pagids since they do not have the same brackets as the OEM pads to prevent the back-and-forth motion when changing direction. You'll usually only get the noise when going from forward to reverse, and vice-versa.
2) & 3) I haven't used any grease when doing my swaps. Granted I have less than 5,000 miles on mine.

Totally normal Pagid pad noise. You ain't heard nothin' yet until they start to squeal. And as for grease, we don't need no stinkin' grease.

Ok great ive been hearing the squeaking nonstop given the different compound, but snapping i was not expecting.

So safe to say this isnt an indication of improper installation?

Yup, the clunk is normal. So is the squealing.

I've tried greasing the back of the pads before, not really sure if it help since it still squealed.

I use a small amount of Bendix brake grease (pads only, not pins) and don't get any clunking or like with the RSL29 pads. By the time I do the 25km heavy traffic drive home from track the squeal is another matter, it could wake the dead.

i literally lold at "could wake the dead"

another reference point here. my pfc08s clunk and squeal like crazy. i dont use any grease on the track pads nor on my stock pads when i reinstall. nor do i bother using brake clean to get all the dust off before reinstall. no squealing on the stock pads either. im at 27k miles.

trackdecals has a sticker that says "brakes squeal because racecar" ive been debating getting that lol

Yep, like others have said, all normal.

My track pads (PFC08's) clunk once when I go from forward to reverse and vice versa.

And BOY do they squeal! In my work car garage today it was comical how loud it was, I couldn't help but laugh to myself embarrassingly as I tried to avoid bursting the eardrums of anyone nearby.

Might have to get off my arse and do that pad swap tonight

I had that sticker on the bottom of my rear window. That and Heal and Toe sticker. I used Carbotech pads on that car, and PFC08 on the M2. The PFCs are louder. It's insane how they squeel.

I've seen that sticker a lot but I don't think I can pull it off with the M2. As modified as mine is, it's still a road car
