How many of you guys are tracking your 991s ?

I think I'm on the track every time I drive my car does that count?

I have a 2014 C2S. Sport seats, PDK, sport chrono, PDCC, sports exhaust. This is my second season of tracking. I do 5-6 events a season. Upgraded brake fluid is recommended. I used ATE last year but prefer the Motul 600 I'm using now. Pagid RS29 Yellow brake pads are the way to go. Long lasting and easy on rotors. I use MPSS tires on 19" BBS wheels.
I just got back from Mid Ohio.

Would love to see some videos as well.

I get a whole season on them. The only bad degredation I have is on one front tire I let over inflate. Otherwise it's pretty normal. The shoulders are fine. They get greasy as they approach max inflation due to heat. That takes 30 minutes. I start in the low 32ish pounds and max you want is 40. I haven't found a better tire yet that allows me to drive out of state to the track, have a weekend on track and then drive back home.

Pilot Sport Cup 2 would be a good tire to try next I would imagine.
Sorry for the load of question. Just want to gather some info on these chassis since I am looking to replace my BMW with a 991 down the line.
Thanks again for the information!

Thanks for the info on the MPSS! I plan on replacing my Pzero's before my first track day. I still have enough wear for another AX or two! Can't wait to get my 991 to the track, that's one off the reasons I bought the car!

I'll be back on the track next year with one of my cars, just not sure which one at this point. Most likely be the Cayman, but it could be all three. I'm too old, too tired and too sick of spending insane amounts of money on a track habit to do a full track prep on my cars, so I'll be going basically stock.

Good to hear, what alignment setting are you running (guess PDCC helps with the shoulder wear a lot as well since it eliminates all body roll essentially)? What wheels are those? What's your opinion on PDCC on track btw?
Pilot Sport Cup 3 would be a good tire to try next I would imagine.

I think Pilot Sport Cups are $$$ but that might be something to look at. Full on R compounds are not in my future since I have no trailer.

Same here, love the PDCC. Couldn't recommend it more. Fantastic on the street and I imagine it's going to be great on the track as well. My Carrera has PCCB brakes too though, and I'm not sure I want to track those, given the issues people have had with those and the cost of replacement. I'm likely going to drop an X73 suspension in my Cayman over the winter and use that at the track instead.

I LOVE the PDCC. The car corners so flat. Yet it has such a supple ride for the street. It's a win-win for a track/street car. My alignment is stock. Haven't touched it yet. Yes, the car has some under steer I could help with some more negative camber. But I can't see any major changes in my future. I don't want camber plates or anything that might hurt the great daily driver ride quality. My wheels are BBS CH-R. Very high quality at a decent price. There are lighter wheels but I like the look and the fit/offset is perfect.

I would try upsizing the front tires to 255 or even 265, if you don't want to mess with the stock suspension. I would highly recommend stepping up to MPSC2 or something equivalent (street orientated R compounds like NT01 are great opinions too, but I am not sure if they sell them in 991 sizes), given that you track a decent amount, they might actually last quite a bit longer than MPSS on the track since the compounds can handle the heat better.

Absolutely right. Tires do not get "greasy", that is a misnomer used by guys who haven't figured out this is what happens to all tires when they let the heat of hard use cause the tires to become over inflated. The best way of avoiding this is to check pressure immediately after each run and bleed out whatever it takes to get down to your ideal pressure, in your case 30.

Great, few last questions, does your car have SPASM? Or just the standard PASM?

I like your idea about tire upsizing in the front. I did that when I was tracking an E46 M3 and it helped a lot. I may try that when these tires burn out. I need to investigate sizes and tire availability. I'll probably get new ones over the winter.
Are MPSC2 and NT01 tires capable of driving distances to and from the track? And are they ok in the rain? I don't have any experience with either tire brand. It's always a compromise when I can't dedicate a tire for track only use. What I buy has to do everything.
