Hah wish I could be Moses in this desert but for now I found a good indy nearby that only charges $90 to change pads (fronts or back) so it's not worth the hassle to me to squeeze the last 10% out of the pads at the track and deal with a change in the middle of a track day. If it turns out that the stock pads are not up to tracking at my speeds, I will reconsider since I will then have to go to Pagids on the track and I won't tolerate that noise on the street.

 

I addressed fluids in another tread recently. Conclusion IMHO is if you track the 991 at any kind of high speed then get a track quality fluid in there bc the electronics work the brakes very hard in corners and the cost of overheating is too high to take a chance on.

Pads: Based on 7 track days in the 991, sticking with OEM for now. Will re-assess in 3 weeks after Watkins Glen event. I'm told Pagids are now available if you want them. If you track OEM, keep an eye on the pads for overheating. It's happened to me only once but hey that's once more than I'm comfortable with in a $100k+ car

 

Dang, that's cheap. I'll need to find a good local mechanic.

 

I thought about PTV plus causing the rear brake to overheat, and I am wondering if you would consider disabling PSM, which would turn off PTV.

 

could you find out a part # for us. I have looked at several manufacturers and havent found anything yet. I run hawk ht-10's on my little track toy and have been happy with them. They are loud though.

 

I don't have a part # but am PM'ing you a vendor (non-sponsor I believe) that sells them

 

Which Pagids are you running?

 

Can you get a limited slip diff in a regular porsche yet?
If not thats a really speed killer on a wet track

 

You certainly can. See info From Porsche.com at bottom of this post. I have the e-Diff on my 991S and it works very well. For example, if you take off from a standstill at full throttle with the wheel turned half-a-turn (admittedly a juvenile act ) you can feel the torque being cut in pulses to prevent oversteer and allow the rears to grab traction. That aside, IMO it's pretty un-noticeable, even on track, because the other electronics keep the car so well-sorted to begin with.

On a separate note, apologies for not updating this thread. To date, I watched my local indy do it last time and am going back for one more pad change (rears) soon. At that point, I'll be to do it myself and post a DIY sometime down the line.

Until then, in preview: It seems very manageable. The caliper comes off after unscrewing two long black bolts (which Porsche recommends you replace each time you swap). Removing/replacing the actual pads is actually easier than the 997, because there's a lot of room to pull them out of the caliper, whereas with the 997 (especially if they had the dampers on their backs) they could sometimes be tough to take out without removing the caliper.

The pad sensor is different on the 991 than the 997. It "plugs into" the bottom of the pad itself. I've managed to keep re-using mine without problems so far but they will probably soon need to be replaced too.

***Main thing to be aware of: There is a silver bracket/electrical tie near the caliper (that I believe holds the brake line or sensors but can't remember exactly). You'll want to unscrew that to give yourself a bit more room to take the caliper off, because its a taught brake line connection to the caliper and if you crimp that line, it will need to be replaced. Better yet I'd suggest if convenient having an extra set of hands support the caliper when it comes off for peace of mind.

Anyways, it's been a wild week in NYC since the storm but glad to report my family and I are OK. Less importantly, Metro PCA is holding a 2 day event at Summit Point starting tomorrow I was hoping to attend since I'd never been to that track, but can't make it now. My downstairs neighbor and his .2RS are on their way though. He left before the elecricity came back on here... Now that is dedication to your craft!

"PTV in conjunction with the manual gearbox, or PTV Plus with Porsche Doppelkupplung (PDK), are available as options for the 911 Carrera models and standard in the 911 Carrera S models. Both systems actively enhance vehicle dynamics and stability. Operating in conjunction with a mechanical (PTV) or electronic (PTV Plus) rear differential lock, they work by braking the rear wheels as the situation demands."

 

Good stuff, thanks for posting.
I'm glad you and your family are OK after Sandy!
Have some friend with property in the Hamptons' and they said some neighbors have had their house simply washed away...

I also hear there's another storm coming your way again...
Hang in there!
