Hi. I own the '04 z06 and will share some toughts..
I think the vette is a faster more reliable car and a better buy overall. One thing that you should consider (that I think only one person may have mentioned) is upkeep on the two cars.
The z06 is failry inexpensive to run. You should expect to paya measly $25-$30 per rotor at NAPA (they are great rotors and last 3 events for me) and change oil after each event. I do tranny and diff fluid every 2-3 events or if I when I think needs it. If I see high tranny temps, I automatically change tranny oil (BTW, so far thats only happened at WGI and Tremblant). If you stay out of low gears the car is much happier I've learned.
As mentioned you may want to get a tranny cooler if you run hard, as you can get the high tranny temps warning if you are really pushing the car. I never bothered because I drive at 7/10ths and I dont think the extra 3/10ths is worth the risk, money or wear and tear on my car (and me!). I'm just out there to have fun so when I see temps go high, I just take it easy for a few laps.
Avoid the pre-2002 z06's as they had all sorts of issues; one kind of major one with the engine block leaking. After 2002 they are great. I've only had one recall for a driver's side diff seal, which was replaced for free. You should be able to get into a nicely maintained car for high $20k's.
You will also need to cycle out the clutch fluid regularly (from the resevoir) as its hard to fully flush - have to take off the header and some other bits to get to the nipple. Its easy to do this though - just get a big syringe and have-at the resevoir. If you dont keep that clean your fluid will go black and the clutch will eventually stay to the floor on high rev shifts - kind of scary when it happened to me once!
The active handling feature is great, especially when you are learning the car. I dont know if the Porsche has this. You can leave it all on initially then graduate to competition mode which will let you slide the car a bit and spin the tires (turns traction control off), but eventually you will want to turn it all off if you are driving hard. I generally run with COMP mode on just in case I hit oil or something. It has saved me once from certain catastrophy at 120mph at WGI. BTW, WGI was MADE for this car. I love that track.
For brakes, go with Carbotech XP series. You can also spend $15 and retrofit 2007 OEM z06 cooling ducts and they make a big difference on front rotor life. The rear ducts are designed well.
For tires, I've only run OEM supercars (whicih are great actually) and Hoosiers which I hear are the best (fastest) for the car, but the ra1's may last longer. I may try them next - I only got three events out of the hoosiers (Fronts are corner-corded, rears have one more event left, or maybe two if I want to slide all over. A set of tires will cost you $1300 mounted! A second set of OEM or replica rims (Which are lighter than oem) are easy to find on ebay for $3-400.
I'd say my only complaint is the seats which are not very supportive for track use. However, they are UBER comfortable for long rides and very non-fatiguing. For $1200 you can get a great seat from Caravaggio that still retains the electric seat features and is comfortable and supportive.
Thats about it. Its a great car. I drive it to the track with a little Harbor Freight tire trailer behind me and its never hiuccuped or complained! I can barely tell its back there. Its also my daily driver and I drive it more often than my other cars. Its just as nice on the street as the track; It truly is a dual-purpose car. I love it and I dont know of any other car on the planet that I'd rather have and could actually afford to track so often.
If you have more questions, let me know. Also check out z06vette.com - its the best z06-specific site, and there is corvettecentral.com which has a larger audience for non-Z06 specific stuff.
