Joe, did you get any pics of the underneath of the seats when you had them out for the bar install?
Would be very nice to not have the belt length change as the seat moves.

Hmm could be. I'm still not convinced until folks that have designed these for the 997 have looked at the 991 LWBs and chimed in with the reason why.

Finally just changed my front brake pads yesterday. Wow, that was probably the most annoying thing I have ever tried to do on a car. Joe, how did you deal with the silly bracket on the back holding the caliper lines in place? It was a pain the *** to loosen, still gave me minimal room to work, and was bent out of shape when done. I did finally get them back on, but it seems unhealthy for the part to put that much stress on it? Why did Porsche do this? Between the center lock and this, it feels like Porsche really has no idea how people use their cars...

I'm hoping someone will make the PFC CUP calipers work on these cars, if they are open bridge..
Anyone have these caliper part numbers?
Racing Brake has an alternative, they posted here with Carbon Ceramic and steel options: https://rennlist.com/forums/991-gt3/...r-991-gt3.html

I know that PFC 11 compound pads have been recommended in this thread. But, my local race shop recommends PFC 08 Compound. They say the 11 is more for sprint cars and 08 is better for track days with a GT3. They say the 08 will perform very well and last longer than 11.
Any thoughts on PFC 11 vs PFC 08 would be welcome. Thanks!

I much prefer the PFC11 over the PFC08. The bite and consistency of the 11 over the 8 is much better, and I haven't noticed a difference in pad or rotor wear rate between the 2. My buddy Ben has found the same on his car as well. Also, the PFC08 are MUCH louder on the street than the PFC11. PFC11 barely make any noise.

Forgot to mention that I flushed the OEM brake fluid out and replaced with motul RBF600. The pedal was starting to feel a bit soft after the 5th track day, so I did the flush. Pedal feels great with the motul RBF after 3 days so far.

Any tricks to the brake fluid flush? Did you use a pressurization tool for a 1-person job, or did you do it the old fashioned way?

Looks like they are single piece with an X brace instead of an open bridge.

That sounds annoying. I haven't seen the GT3 with a wheel removed (and my GT4 isn't built yet), so I am not sure I understand the bracket problem. Is it something that could be fixed by having a longer custom braided brake line (to replace a hard line)? Does anyone have a photo of this bracket and brake line issue (sorry if I missed it in the thread)?
Thanks!
Thanks!
