These are the lines I used: 996.355.587.03 and 996.355.588.03. They are a direct bolt on. The superseded 997 part numbers ones you listed are the same lines and obviously will work also but they were about twice as expensive then the 996 parts when I checked. If you can get the 996 part then go with that.

 

You need the 997TT offsets when used on the 996TT...

 

Gents, how about 380mm discs on the 997 turbo stock runs 350mm on the front ?

 

pwdrhound, what brake pads are you running?

 

PFC 08 front and rear. Best pads I have ever run. Just drop them in and go, no bedding, relatively low noise (for a race pad anyway), same feel all the way to the backing plate. There is a reason Porsche Motorsport finally switched to these as standard equipment from the crappy Pagids.

 

I have not tried PFC pads yet. Why did you choose PFC 08's over the PFC 01 front and PFC 06 rear combo?

 

The 380/350 997GT3 brakes which I run utilize much larger rear calipers (50% more piston area than the 996 units) in combination with 15% less piston area in the front calipers. As such, the 997GT3 brakes are much more biased towards the rear of the car. The 08/08 combo works perfect. For a normal 996TT/GT3 set up the 08/01 or 06/01 combo is the way to go to try to get a little more bite out of the small rear calipers. You definitely don't want to go 01 front 06 rear. You want 06 or 08 front and 01 rear. The 01 is PFCs most aggressive compound so you want that in the rear. Hope that helps.

 

+1 for stock 996 GT2/3 brakes and PFC 08F/01R. Big fan of that combo.

I need to save up for these 380mm big boys pwdrhound is teasing us all with.

 

Thank you for your clarification.

Now to find the $ for a caliper upgrade

 

Running 01/01 and pretty fantastic at track. Just need to manage the heat. I now have the big GT2 Cup ducts and will be using them at the next event mid Sept.

 

Bump....

I just add 996 GT2 380mm steel front rotors with 997 GT3 Brake Master Cylinder, But something just happened...engine check!! seems the floor is too strong, please help ! how to do next....


And for comparing here is 996TT stock brake master and 997 GT3..seems GT3 brake master is bigger, I have to use adapter to install on it..


And problem is here....






Please help...I really appreciate

 

When the smart folks chime in I'm looking for the hard line adapter for the M/C also

 

pwderhound has them. i bought one a yr ago and tucked away just in case....

 

Why changing the master brake cylinder? Im am running 380 mm ceramic discs and 6-piston-calipers on the front and 350/4 on the the rear, just like the full big ceramic package of the 997.1 turbo on my 996 turbo.

The 996 master brake cylinder just works fine. Before it had to feed 4 larger pistons and now 6 smaller ones. You won't notice the difference in the pedal.

The difference of that brake on a lighter car you will notice for sure

 

Pics of 997.1 ceramic brake on a 996. The car is a bit lower now as it was at that time:
