First AX in 991.2 Carrera T
Drove my new T in my first AX yesterday! Wow! Great car! Exceeded my expectations. Ran it showroom stock with stock PS4S tires . Haven’t touched the car in terms of alignment from Factory. Ran 31 PSI F 34 R . Ran Sport with sport suspension setting and ESP off/ limited mode.
Im a long time mid engine Porsche AXer and have to say the T rocks. Good turn in and RAS is mind blowing in tight stuff. I could definitely tell I had more weight out back compared to my past Cayman but T does so much more in terms of braking and ability to get out of comers quickly. And quickly learned in slaloms rear engine car isn’t as forgiving as my cayman was. More on rear axle steer - man it takes some learning to optimize as I found attacking some slow sections and coasting through turn resulted in some wicked fast turn in all the way though turn. Not intuitive to me as I usually use throttle brakes to get car to move in turn where as RAS just makes car rip through slow stuff if you do it right.
wasnt tracking all of times but I was in realm of street tire class GT3 and GT4 cars that were running RE71 or Cup 2 tires
PS4S is decent tire. Not huge amounts of grip but very predictable tire. I can’t wait to see how car does with comp alignment and re71 setup. I’m evaluating wheel setups for SCCA I think 19 inch with 255 front and 305 rear will be way to go. Considering forgelines but man they are expensive! ....I’m still a cheap bargin hunting racer so looking for cheaper solution to 19 inch setup. And still not overly thrilled with scratching calipers and rim barrels. Sure wish Bridgestone made one size up in 20 inch. I wrote them but haven’t heard back yet. Seems strange given so many cars are rolling on 20 inch wheels now.
cant wait to see times to get benchmark. My driving was off as it was first AX in 6 months and first time in this car . By end of day was starting to figure it out and turned a couple of quick times.

Great update! I think the RWS is a great asset to making the rear engine 911 really handle. With all the active stuff going on, I'm sure there's a learning curve! Gone are the days of all mechanical and simple controls. What adjustments did you have to make to driving style from the Cayman?

Sounds fun and you'll acclimate soon enough. I had a Cayman S that I tracked then a 991.1. I thought the stability under braking and accelerating out of corners was a big difference moving into a Carrrera.
I don't think you can use 19" wheels with RAS. Double check or someone who knows for certain chime in.

I came out of 2100 lb wide body 987.2 cayman S running 315 rear And 295 front A7s. It was dedicated XP autocross car. So my perspective is a bit warped however I occasionally drive my wife’s 981 Boxster S.
biggest difference for me is that T turns better in some of those elements that induce understeer in 987/981 platforms.. power delivery is better as well - T gets up and goes in slower elements compared to cayman .
cayman required a lot more massaging from me to make it do right things. T just does what I ask of it. I could get away with corrections in lightweight Cayman mid slalom so takes way more focus to assure T is setup right or it feels like big pendulum in back. . With more seat time I’ll get it.
But damn if T just feels a lot like a race car with a few little tricks like RAS. I think biggest thing for me is learning to trust the car to do right thing. I’m still in habit of inducing oversteer . With RAS car gets around turns faster iif I just keep Smooth arch through turn. Car also can go faster in slow turns than feels natural to me due to RAS.
While T has little turbo lag still takes good timing off turns to get on full boost with out that little hesitation . I m still getting feel for cars handling under power I was a bit timid to explore limits in faster sweepers requiring acceleration.
I think when I turn off esp with just a quick push it limits ESP . I ran that mode and was happy with car but as I experimented seems by holding button it totally disabled system. The limited setting allows some pretty radical slip angles so I didn’t feel need to turn all way off but as I get faster I may try that. Limited setting caught a for sure spin as I exited slain feature.
braking in T is way better! What T might lose from mid engine cars in holding speed through elements I think it makes up in allowing car to charge elements and throw out anchor car last second ....can be hauled down from speed quickly with little drama.
As as far as SS car in SCCA don’t know that it’s going to match GT3 at national level but it’s capable enough to do ok in local events. I think it’s on par with GT4 on some courses where that tall 2nd gear puts GT4 at power disadvantage.

I think with RAS forgeline is the only 19" wheel that will fit. You'll need to talk to them to make sure.
The problem I'm having lately is getting someone it put RE71s on, because they are not weight rated for a 991, so a lot of companies won't install them.

Shows the 305/30/19 tire has a max load of 1874 lbs. So that's like 3750lbs for the two rear tires which is more than the whole weight of the car.

Seems odd given my car weighs 3100 lbs and has no backseats . Regardless I use race tire shops for install so no worries on install. If you show up with set of wheels and tires and say it’s for a race car most standard tire stores won’t ask but I wouldn’t leave tire install to anyone but place that has experience with nice race wheels.

That's bizarre...

850kg vs. 875kg. Sheesh.... it's probably for a 911 with 4 full adult passengers.

Car looks great! I do it for fun too but headed to an SCCA national tour event in April and I don’t want to be too embarrased. I did get within tenths on OEM setup to fastest SS car on re71 so just need that extra little edge..

I just looked up the specs for 102w vs 103w.
