For anyone contemplating doing a 996 turbo 6 piston 380mm brake upgrade using racing brake adapters mentioned in this thread, know that as per the owner, you cant buy the adapters without spending $2k+ on the rotor/caliper kit.
I'd read all about the RB quality issues all over the forums,but figured I'd form my own opinion through dealing with them directly.
Multiple phone calls and emails unreturned, finally when calling directly the 4th time,,the owner was heard in the background,, stating the parts are not for sale separately.
Be advised Porsche also sell caliper brackets, that are also mentioned in these threads that im investigating to see if suitable.
My current set up is 01 996tt with 08 gt3 cup front calipers,,looking 380mm girodisk rotors and the Porsche adapters. I waiting to have the adapters in hand b4 purchasing the rotors. If anyone has 1st hand experience and part numbers,,that would be appreciated. In

 

Is there anyway to adapt the uprights with the 380mm spacing to be used with the 350mm brakes. If not I may just sell my uprights (996 RSR) as I don’t want to go 380mm

 

Hi everyone, just bringing this thread back up. I am aware that the adapters from RB are no longer available for purchase. Is there another company producing the adapters for calipers?

2005 Base Carrera and I would like to run 6 piston calipers with 380 rotors.

Thanks in advance!

 

I have a 997.1 4S with the GT3/turbo pccb calipers and steel disks.
Got some Zimmerman rotors from autodoc, some EBC front pads and ATE rear pads.
350mm all around.
I track it and the brakes are good but not exceptional and you can definitely still get brake fade quickly if you drive like a monkey. Doubt it makes a huge difference.

 

What bracket are you using to bolt up pccb caliper to be able to run 350mm rotor?

 

So you're wondering if the stock master cylinder's gonna cut it with the new 6 piston front brakes. Does it need a GT3 master cylinder upgrade to keep up with the increased brake power?

 

@Exposer ,
That question was from 10+ years ago, hopefully they figured it out...


Watching.

Just FYI for anyone interested. On my 2008 997.1 C2S, I installed a set of 992 GT3RS Calipers, Pagid Pads, and Girodisc A1-156 (410mm) and A2-156 (390mm) Rotors with just stock front adapters and rear spacers.

 

What pads are you running if i may ask? Race or street?

 

Unfortunately stock street pads. Great grip but way too much dust. Since they were included, I’ll use them up.

 

is it same pad as what one would buy for 380mm iron disks?
