I personally prefer the more linear nature of NA power delivery of the 4.0L over the 2.5T but that's just me. Aside from that, the cars are identical in virtually all other aspects with the 4.0L being slightly heavier and worth about $30k more. I honestly think they both are butter knives in the SS gun fight, but understand where the cost factor comes into play even if it doesn't reflect outright performance. As for the C5Z vs. C6Z vs. C7GS, several top 10 nationally AS drivers have driven each other's cars and had this discussion and concluded the C5Z is competitive when the C6Z gearing makes it a 1/2 gear tweener course as it falls in the C5Z sweet spot. Everywhere else, the C6Z is faster. As for the C7GS, I've done three events in one and wasn't as impressed as I thought I'd be. I mean it's a big, fast car. The metrics work against the C7GS has 40 less hp (if that matters), is 300# heavier (3131 v. 3444) so tire to weight comes into play, 1.3" wider and 2.3" longer so less agile, lower transitional speed, but evidently little more tame. That one is a little tougher but may be reasonable.

 

I don't know what FB group you're referring to. Tires are also different. BFG, re71r, and 660's required different bar/pressure setups.

 

I autocrossed a 718GTS turbo-4 at one event. I thought it was a match for the C6Z everywhere except 2 places: the 2 slow corners where it fell off boost. I lost 0.5s in each of those corners. So, very course dependent. Maybe, with lots of practice, a good driver could do things to reduce the damage.

 

Managing turbo spool is always interesting. With my Golf R I started experimenting with brake boosting during slow speed corners with left foot braking. Hard to time it right but the R also has a ton more turbo lag even at higher RPM than the GTS seems to so far (although I've driven the car a grand total of 23 miles, thanks to bad weather and lots of salt!).
Might also cause more tendency to understeer with rwd than AWD.

Manual or PDK? I don't think any Manual Pcar will be the one to have.

 

Rachel Baker won the Bristol pro in a 2.5 GTS a few years ago.

I ran a 4.0 GTS locally and found the car to just not have the front end to really do what you want to do, at least in SS trim. I mean it's not bad, but it's not as good as the GT4.

 

Yep, I was working course while she was running. She not only won, but she beat a really good driver in a GT3 in the process.

 

She was in a GTS2.5 not her (now sold) 981 S? interesting. Even more reason for me to try and get her to give me a bunch of instruction this year!

 

There’s no reason NOT to have her help if she’s available.

 

Yeah absolutely. She's gone for a few laps with me in my old car, was always super helpful. Only problem is we'll be in the same run group most of the time!

 

What you guys are starting to see, while looking one car at a time, is that almost any car from super street could move to AS and leave the c6z at least reasonably competitive on most courses. That’s the unwillingness to admit that the C6Z is currently classed dominantly rather than competitively.

considering that not many serious competitors are likely to buy a C6Z with so much turmoil suggested around the class, and also people are likely to move out / give up… you’re not going to be getting an honest look at the potential for that class for a minute or two. I say, ALL the decent cars from super street move to AS, be a little more aggressive moving interesting cars from AS to BS. Everyone in super street gets to wag their tail a little since they’re now in easier “AS” (which was always basically as fast as SS), and then immediately class the new 992 GT3 RS, 992 GT3, c8 z06 and hybrid, 718 GT4 RS, whatever crazy Tesla plaid thing there is, in the new SS. Let super street go back to what it used to be: cars that were too expensive to autocross before the time when a decent new pickup truck cost $70k.

I would bet money that what the SAC / SEB will actually do is move a few dumb choices to AS, be confused by the skewed data, missing the forest for the trees, ignore reasonable suggestions by the membership, be asleep at the switch when someone figures out the actual best mouse trap for the class, and then finally for the cherry on top, they’ll make another knee jerk reaction that will screw up at least one or maybe 2 classes a couple years down the road. These people only think one move at a time

may the odds be ever in your favor.

 

New FasTrack out Somewhat clarified the OAP... Somewhat.

No word on decision for SS/AS changes. Guess I'm starting in SS...

 

The proposal which is out for comment on possible moves to AS won't be decided and announced until after 2023 Nat's.

 

Ah, thought it was for this season. Not that I'll be competitive this season while I learn how to drive RWD anyway!

 

Some minor changes to AS in the latest FastTrack (May 2023) for Porsche cars. Basically splitting 997.1/.2 cars between BS and AS.
