Pad for DD/HPDE duty? PFC-Z, oem Z06, or Hawk HP Plus?
It's going to betime to replace the pads on my father's Z16 soon... trying to decide on pads. He doesn't care to play the swap game, so looking for something that's happy doing dual duty. So far the oem pads have been great, but is there a better option?
I've heard youcan get the PFC-Z pads at advanced and/or auto zone and they'll warranty them for life? How do these perform in comparison to the oem pads?
I remember reading awhile back that hawk or PFC, can't remember which, made the oem pads for GM. Anyone know which it was, and which compound it is? Maybe the Hawk HPs?
Thanks,
Brian

^ It's still on their website... and my father called auto zone and they have some at their warehouse.
I don't think he needs them just yet, as he's run 2 events on his oem pads, but just getting ready just in case.

Hawk HPS / HP Plus
Hawk offers the HPS and the HP Plus...
HPS pad is a "Plus 1" for street applications. Every good initial bite with good torque in street driving requirements. Low heat good stopping power over OEM.
HP Plus is a "Plus 2" for the sport minded street driver and for track time driving. The "Plus" have good initial bite with steady torque up to 800 F. This heat range is generally good for the "dual" purpose usage providing you are using a true street tire. If you use a “DOT” tires for the track you may exceed the temperature value in the pads which will create other issues.
The noise issue is probably a result of the pad surface “glazing” after experiencing high temps. This is common in most all performance pads street or track. A couple of hard stops will reduce the noise until the pads glaze up again. .

Don't have any spec data but been running PFC-x for most of three
years. Now I understand that track folks don't care about looks but the
most noticable thing is the deposit layer they put on the rotors. It isn't
shiny like stock pads, basically looks dirty. However, since I got to
using the brakes harder using the X and when I switched back to OEM
for one set I had a 50% pad disintegrate in a 3rd session I've stuck with
the PFC product. I don't switch, so they stay on my DD and then do
track duty when required.
As to availability I get mine from Mark at Motorsports Image in Roseville,
CA, forum vendor. The word I got was that PFC doesn't run them all
the time, just in batches so some people stock them when available.
They do a good job in double duty, no squeal and adequate bite for
use with street tires. They generate enough heat to build up to cracked
rotors for me after 6-8 track days for the fronts, pads lasting about 3 days.

I am running the HP Plus. On the street and on the track. They work very good and wear very good.
They are noisy as &^%(@#! They do go through quieter moments but are still annoying for the street.

I thought the HPS did better on the track then the PFC-Z. I have some Carbotechs now and in a different thread it was mentioned to just get some 8's and use those for both.

Yep, I've run them. FWIW, AZ might have them on their website, and the computer might see them in the warehouse, but last time I tried to get some it was a NoGo. And, just to show you how AZ stores can be, the store manager honored my warrenty (2 year now, lifetime warrenties have been gone for a while) by buying me a set of Hawk HP+ pads. Obviously that's way beyond the call, but shows that chain stores can still stand out from the rest (just like the old days).
I do think there are some CF vendors that have Z-rated pads in stock; you might do a search and see what pops up.
As far as the pads go, understand firstoff that my DEs are reasonable, relaxed events. I probably drive at 8/10 of my abilities, reasonably early in the braking zones, just having a good time. Autocross is different, braking as hard as possible, late as possible. But, obviously, even with four back-to-back runs, still not close to the duration of a DE session.
I've never had problems with brake fade or pad crumbling. Now, if your Dad is running V710s as deep as he can, then they'll probably not stand up; but I infer he's planning on running kinda like I do.
HTH, and have a good one,
Mike

Right on the mark. HP+ pads are terrific for autox use and work well on the track. Use them for what they are intended for and they won't be terribly noisy.

I replaced stocks with HP + last year and they were fine with stock tires and worked well for autox and about 6 DE days. I still use them for street and autox.
I never had any squealing problem with them, but they tend to dust up and are harder on rotors than stock pads ...
After running CarboTech 10/8 to and on the track I would suggest that the 8's all around might be ok for street and occasional track ... one just has to know what their cold characteristics are and adjust.
