i went and shot video and learned a few things. The NJ Porsche club allows non-Porsches into the club, and the autocross begins with the X class, which would be us. Sadly, no F's were running yesterday, but I filmed a Lotus Elise to show what the track was like.

Motor Trend's figure 8 test is an indicator of how a car will perform in an autocross, it tests every aspect of handling through all directions. Though this graphic is from 2008, the 2012 time of an iS-F at 24.8 sec. is faster than the Porsche 911 Turbo, the Ford Shelby GT500, the Mitsubishi Evo, the Corvette, Mazda RX8 and Mini Cooper, and came within .2 seconds of the Audi R8. I think the F could surprise a few people at one of these things.

here are the results of the autocross I went to. Interesting that the Elise I filmed had better times than any of the Porsches. The 93 RX7 had the best time of the day.

Autocross very much favors light weight, and the more traction (better tires) the faster one goes. Counterintuitively, tighter lines/less late apexing is also usually faster. Cars are classed and "indexed" to allow drivers to compete for overall standings.
The IS F in stock or close form is in F Street class, and is very competitive, at least with the limited slip diff. "Street" classes allow limited modification - you can change ONE sway bar, do a cat-back exhaust, and I believe one can change shocks (but not springs - no coilovers). Tires are restricted to 140 treadwear (200 next year), and wheels must be stock width. If you go beyond that you're into a "Prepared" class.
It's huge fun, not much money, and almost no risk compared to time trials or (especially) wheel to wheel racing.

I think a newer F with a proper LSD and some decent tire will do pretty damn well despite the weight. Its no Lotus but she can dance with good tires

Well... I have 2011 F that I track and I'm quite happy with it. It never fails to put a smile on my face. I can pretty much stay with the lead pack, sort of 911's. The only thing I did to it is upgrade the wheels and brakes.
It's rock solid reliability is a key thing for me. Never had any sort of problems with it.
On the other hand I also own a Lotus Exige Cup 260. Of course it handles better on the track but it's expected to do just that. It's quicker than anything else I've ever driven on the bends but I loose all the advantages I picked around corners on the straight stretch.
To sum up, the F ain't shabby at all. It always gets thumbs up and earns respect from other drivers.
