I know this has probably been done before, but...

Ive just brought a GT3 997.1 in the last 4 months, and I'm dying to take it on the track. The only problem is, it has Ceramics which are in great condition and i do not want to kill them as i understand they will de laminate when pushed hard.
The questions is do i upgrade to Alcons with RS29 and endless fluid or go PFC Brakes and pads. from the little research I've done are these the best, as the brembos are for track use only??

i have also put Cup 2's all round and had a giro set up as well as a service 700 miles ago.
Is the any thing else i should do before i track it?

Alcon/PFC08/Endless

This is what I run and I can go all day long. RS29 are no good.

Interesting, I've used them in plenty of cars successfully. Care to elucidate why you don't rate them ?

RS29 work for some people.

I just found they gradually get worse. They only can take a number of heat cycles. Done at or before 50% wear. And you don't know what you get. Guess they work if you brake very late/hard and use the brakes as less as possible. This is really how it's done.

I do 5-10 laps at SPA/Silverstone or 20-30min stints. RS29 long pedal for sure! PFC08 - always a solid pedal! You got brakes all the time. Braking is more precise. You can run them down to the back plate. Was amazed how much better the PFC08 are. They are a bit harder on the discs but I don't care about that.

And those gen1 ceramics are no good either. Once you are through the first set of pads the disc surface is already in a rougher state and will eat through the second set of pads in no time....

I've used Alcons and PF. I've also run on OEM on my old 99 RD3, including with RS29s, when I raced it in the Porsche Open. These cars are well braked and I'm not sure you need the highest specs unless you are endurance racing. None of those are bad answers, but for a few track days you could use normal Pork steels. If they're the same price as Alcons or PF then those are better, but if a lot cheaper then it's an option. These cars are built to be used hard and the steel brakes are good.

Wouldn't they be gen 2 ceramics on a 997, I thought gen 1 were 996 only? My 997.1 turbo has gen 2 ceramics, or at least I thought they were?! Then gen 2's are supposed to be better at dealing with heat.

Hmmm, never heard of those issues to the degree you've described. You're right, heat cycling does affect the co-efficient of friction, but the RS29 was introduced as an endurance pad that had more bite than the relatively wooden RS19 that proceeded it, and thus it's performance shouldn't drop off to the degree you've described.
They are fiercesomely expensive, but I wouldn't use anything else.
I know some early PFC pads caused substantial damage to the car's paintwork, is this still an issue ?

You are probably right. Had them on my old 997.1 turbo. Second set of pads went quick.

Try the PFC08 next time and let me know. They are miles better.

No issues with paintwork. smile Possibly they early PFC01? They were very hard on the discs from what I heard.
