So is my 09 c4s the same as a turbo?
When I recently enquired about fitting 380mm pccb I was told I would need turbo uprights and other parts

 

996 Turbo & 997 C2S,C4S,T4S all have the same brakes and rotors. 997 Turbo 350mm front brakes are a direct fit.
I thought the 380mm system uses a caliper spacer and therefore would fit?

 

Johny thanks for your post. That's the reply I was looking for, to know if they are a direct fit. I will let you know what happens after installation.

After I am done with the brakes I will start planning my engine upgrades!

 

Thanks for the info.
Ill be at the dealers again after work on friday.
if the parts guy isn't too busy ill ask him to check some part numbers for me.

 

If you're tracking the car on occasion, try a cheaper upgrade first. Brake fade is related to overheating & inability of the rotors to dissipate heat. This is one of the advantages of the PCCB's, but even these can sustain heat injury. Try upgrading your brake vents to GT2 vents. You have to do a custom fit, but the modification is easy. You could also use a better pad set as well.

 

What pads do you usually use? I have to say i prefer Ferodo DS2500 all around.

 

Sorry to bump an old thread but I've got a 997.1 C2S with PCCB which I track a lot so I want to put steel disc in.

I know in the rear 997.1 turbo disc fit fine.
But can I fit 997.2 turbo 380mm front rotars with a caliper spacer?

 

I think there are some companies offering such upgrades.

 

Surely I can just buy from Porsche, they sell the 997.2 Turbo 380mm rotors and the bracket for the calipers. So I can buy the parts from Porsche, question is does anyone know if they will 100% fit or has anyone tried?

 

I have put in my 997.1 4s the turbo brakes front and rear but i didn't made any upsetting in the brake bias they told me that is working fine...do i need to go to ask them to do something?

 

Were the front rotors 350mm or 380mm can you remember?

 

They are steel brakes not PCCB so they around 350mm

 

The 997.2 Turbo does not have 380mm front rotors unless they are PCCB. The steel 350mm rotors will fit as long as they aren't the center locks.

 

That information came from a Brembo engineer. Maybe they played with the pad compound? The GT3 and Turbos use a rear caliper with bigger piston diameters and therefore clamps/squeezes harder thus upsetting the brake bias. I will try and find the message he sent me. There is a reason Suncoast Porsche removed the 997 Turbo caliper upgrade for the non Turbo 997s from their site...

 

Found the message:

"Installing 997TT front 350mm discs and 6-piston calipers is fine. The rears are not recommended due to the major piston size increase, just as on the 996TT. You can upgrade to 350mm rear discs with your original calipers using a proper spacer and longer bolts. I know that these are stocked by the Brembo distributor.

In regards to 997TT PCCB's the fronts would work provided that the factory adapter bracket and additional bolts are used that adapts from the factory upright 142mm spacing to the 225mm required with the PCCB calipers.

For the rear, you could not use the 997TT PCCB calipers because of the piston size increase. You would have to use the 997 non-turbo PCCB calipers. "
