Changing brake pads on a 991S

SRF is a waste of money and may not even be suited to the seals in the 991. You might get a Porsche dealer to confirm it's acceptable, but it's still a total waste of money. Ate or Motul are above the limits of the rest of the system. I run boring, old Ate in an RS 3.8 running Hoosiers at decent pace with zero problems.
I'm curious about the Brembo rotors. Last I checked, no OEM/aftermarket rotors were the correct thickness for the 991 calipers. I'm keen to upgrade to slotted rotors from PFC, Brembo, Stoptech or equivalent. The factory pads are the first weak link. Plus braided flex lines. A little oversized with spacers for the calipers would be fine, but right now, I don't think the brakes need anything except light, durable rotors. The factory rotors are giants, which I think is mostly related to the rears being over-engineered for PSM and PTV.

I agree with you on the pads. I wore out 2 sets of OEM pads last season and i've switched to Pagid RS29 now that they're out.
The brembo rotor kit I am referring to fits the stock calipers. They are stock width, but are 10mm larger in diameter in the front and 20mm larger in the rear. The part numbers are 102.8010A and 202.8009A if you're interested. I got a pretty good deal through Gruppe Werks (www.gruppewerks.com) on the kit.

I got my RS-29s from Gruppe Werks, good price and good service. Quick turn around.
I also purchased my SRF from them. I love the stuff. I only bleed my system once a year with SRF and it has never failed me.
