looking for info on 991GT3 pads , mostly track time , did conversion to steel with oem calipers ,have 06 c2s with track set-up always used padgid not sure if they offer pads for this GT3

 

Try Ferodo.

 

Call Clark at Apex-Performance Ferodo 3.12

 

Call Clark. I have been using the Raybestos ST-43 pads, great on track, just got back from VIR yesterday. That said, they are super noisy, although usable, on the street. I was thing of trying the Ferrodo DS 3.12 next go round and compare. Good luck.

 

How do the ST43 operate when completely cold on street, say emergency stop after 20 mins at 60 mph on the freeway?
The Viper ACR-e guys speak super highly of the ST43 (some of ST47 front and ST43 rear) for track use. I'm planning on converting my Viper ACR-e to girodisc iron rotors + ST43 over the winter.

 

ST-43 are completely usable on the street. No issues with cold use, around town (not track) usability is fine, other than the noise. Someone here said they sound like a dump truck, which I agree with.

 

To each their own, but if you liked/used pagid yellows in the past, you probably will not like the 3.12. It’s the opposite of the endurancy, low friction, high heat and pedal pressure requiring pagid rs/rsl29.

I have a strong dislike for the yellows, but it’s obviously very subjective, so you should try both on this car to see for yourself.

 

check PFC...
have them on my GT3 and really like them a lot.
