Hi guys,
I have an 06 C2S cab 6sp that I plan on taking to a track day at Thunderhill in October. My question has to do with the stock brakes: Will they hold up? I have plenty of track time under my belt (almost all at this track, but with an M5), so I will be on the brakes hard. If they won't hold up in stock form, what would you suggest? Different pad, different fluid? Thanks.

 

They are fine

 

just make sure your brake fluid is fresh. Stock brakes are surprising good. Once theyre done you can always upgrade the rotors pads to suit your tastes.

 

stock brakes/pads are fine until you advance past novice stage...then you may want to consider upgrades.

 

I drive my 05 C2S Cab at Calabogie, Mosport, Tremblant - on dry days when I have the MPSC's on I usually put in Pagid yellow pads. On wet days when I stick with street tires, I've generally leave the regular OEM pads in. Only once when things dried up did I run into a wee bit of fade on the standard pads.

Definitely bleed if not flush the fluid if you are expecting to be hard on the brakes.

Sounds like you know the track well and plan to drive hard ... However, since this sounds like it will be your first track time with the 911 - suggest that you take it down a few notches at least at first to get the feel for the different weight distribution, handling, etc. In which case, the standard pads would be fine.

 

I use Castrol SRF brake fluid and Pagid Yellow pads.
Never an issue. Stops like crazy.

 

well, if you will be placed into green group with PCA DE your previous experience will not help much as you will be held behind people who are on a track for a first day ever.
I would vote for RS29 pads. pagids do not eat rotors as bad as more effective pads, but a lot of people prefer PFC01 as they have more initial bite than pagids.
for fluid - motul 600 or similar class fluid is a given. brakes are your life, so, you got to pay attention to them.

 

I would think if you are used to tracking an M5 you are in for quite a surprise with the Porsche breaks.

 

my m5(e39) brakes sux on the track. Ask me how i know :|

 

Guys,

Thanks for all the great advice.
I'll definitely take it easy at first so I get used to the 911 on the track. I also think I'm going to be surprised by the Porsche brakes...............my old e39 M5 was only good for about 3-4 laps before the stock brakes were toast. Most of my track time has been in my 125cc shifter kart, so I'm hoping for a braking experience somewhere between the old M5 and the kart.

 

stock pads start to fade if you go from 120-130mph on main straight down to 40mph.
what you can do easily is to make sure you have air ducts installed - cup car`s are best but gt3 ones also are better than nothing at all.

you got to have one or another. cup car ones do make real difference. for fluid i run ATE blue /ATE 200 as it is easy to change it when it changes color. still, motul is probably better.

 

Geez... I sure hope you meant to say "...with the Porsche brakes."
