I suppose I could order now, planning ahead for next year. That's not a bad price, especially since I paid twice as much for HRE's built using the same cast spokes + roll forged barrel process. On the other hand, I did order from a company who understands that their roll formed barrels are not "forged". Forgestar seems to like using the word "forged" all over their website though their wheels have nothing to do with forging. They also use monoblock in the descriptions, like other companies use to describe their actual forged wheels. It makes me trust them less.

Well, if you don't mind going cheap and (likely) don't care about weight so much there's these. You'd need a ~10mm spacer in the rear.

I can confirm both. A full set of custom Forgestars will cost less than a set of off-the-shelf OZs from TireRack, but expect it to take a few months as they make every set to-order after you order it and they have a backlog.

I'm really happy with mine though it's a bit annoying to have to deal with hub rings and you'll need conical lug bolts. (Protip: lubricate the hub rings, you can't balance the wheels without removing them, and it and it makes it a LOT easier.)

You can order a SV-104 18 or 19 to meet your race specs. They have a section on this web site and a group buy I believe. I bought this exact wheel in Sept of last year with a powder coated black chrome finish 9 in offset of 47 f and 10 inch offset of 35 r. 18.5 lbs f and 19 lbs r. Porsche Signature, Ivan is the guy. Specify the hub hole opening to fit the Porsche crest cover. i am using RE71R's 255/35/18 F and 275/35/18 R. Fit is excellant. I do not run stock class, but in GT3 under PCA rules which allow for wider wheels.

A 987.1 S won the Finger Lakes Championship Tour this weekend. I briefly chatted with the owner who seems to think the base 718 might be able to get it done in AS. The 987.1 S had 265/285s on 8.5s/10s, PASM, and 0.8 degrees of front camber. The 718 certainly seems able to get more camber, weighs less, and can run 8.5s/10.5s if you go with 19s.

Looking at results from the Champ Tour, AS's leader was 2.325 seconds faster over two days - so a base 718 would need to be 1.1625 seconds per day faster than a well prepared 987.1 S (62ish second course).

At Nationals, AS's leader was 1.04 seconds faster over two days - so the base 718 would have need to be 0.52 seconds faster per day (60ish second courses).

Finally, an unscientific comparison (not balancing for autocross setup, modern tire technology, or different conditions) at fastestlaps.com had the following:

HOCKENHEIM SHORT
987.1 S - 1:15.50
718 Base - 1:12.40

AUTOZEITUNG
987.1 S - 1:41.20
718 Base - 1:39.20

So . . . . . who wants to spend $65,000 and lure an alien to drive their base 718 to see if it can compete in AS?

I think a 718 can be very interesting option in AS. Looking up a few acceleration videos on YouTube it seems the PDK does about 71-72 mph in 2nd and the manual is good for 76-77mph. I think the PDK is the right choice on the 981 since the manual is far too tall. But on the 718 it'll pull pretty hard from just about any RPM and 76mph is pretty close to perfect to avoid 3rd on any normal course.

Seems like a properly built one is going to be at or very close to $70k, a very expensive experiment. Sport Chrono, PTV, and PASM are the must haves. Did a quick look and its nearly impossible to find one with PTV but a custom order can fix that.

I also wonder how it would compare to a 981 GTS if that was moved to AS.

I'm also new to P cars but very fair points. I just considered them 'must haves' based on the earlier cars but may not be as important for a 718.

The biggest benefits I see for Sport Chrono are the dynamic engine mounts but not sure what the real world benefit of that is. Also gets auto rev matching but probably not be a problem since 2nd gear is tall enough anyway. You do get 'Sport Plus' mode which pre-conditions the turbo for better response but I think you get that in the 'Sport' mode for non-SC cars anyway. PDK cars get LC but I think manual is the way to go for a 718. So yeah, open to more feedback but looking like a marginal benefit to SC on a MT car.

For PASM, not sure about the rates but the car is 10mm lower. On the 987 cars PASM was preferred over the standard suspension. I am going to assume that holds true here too, if anything for the lower CG.

So yeah, maybe none of these are 'Must Haves'. Though I think I've been brainwashed by Porsche but I'd buy both of them anyway. I also think both options help with resale too so you do get some of it back.

Also 4 way sport seat plus. Sport mode takes some more nannies off.

The largest benefit from Sport Chrono on 987 and 981 is the effect Sport Plus has on nannies: these cars are FRUSTRATING to drive at the hairy limit in normal or sport because the nannies keep ruining fun and costing time. Even with PSM disabled, it still engages during trailbraking which isn't necessarily bad (1-wheel magic braking could, in theory, be faster with than with normal braking), but... it also retards the throttle. For far too long afterwards. Ugh! Sport Chrono in Sport Plus also maintains full throttle right to the rev limiter (another important plus), and for PDK cars, changes shift programming to be more aggressive in gear selection and also different clutch programming for faster shifts that dump more power into the clutch (less smooth, more fast). I consider Sport Chrono the only "must-have" option for 987, even more important than PASM.

Maybe 718 is different, but I suspect they continued with the same philosophy as before; someone with a 718 will have to chime in.

I have this thread bookmarked (see post 12) in the unlikely event I'll ever get my 987S.

cretinx

So wait - you're saying without sport Chrono you can other fully disable the nannies?

sjfehr

Correct. Even if you turn PSM off, the computer will automatically (and quietly) re-enable it whenever the brake pedal is pressed. The only workaround at present is disconnecting sensors to cause PSM to error out and disable itself, but this can severely impact PASM and also cause issues with some other systems that use data from many of the same sensors, like ABS.

There are also some GOOD things PSM does that aid performance; engine braking management, for instance. If you disable it (via button or sensor disconnect), you lose the good stuff, too. Sport Chrono in Sport+ mode fixes this all, and without the need for hacks.

The 996 has the same PSM re-activate during braking and in high g's, but as soon as you're off the brakes the PSM is off again. Honestly, I've found it pretty helpful at autocross, but the 996 requires a lot of reeling in due to the poor balance.
