I do not mean to thread jack ya here, but I think your question has been answered. 323 IS legit...
4U,
In regards to your question about my 6 inches, I think I could have cleared my 24s with 5, maybe a little more. Just like you, you have already pushed em out 4 and you do not want to do it again. The last thing I wanted to do was glass em and realize I needed to redo it because the tires are hitting the fender and smoking when I am mobbin down the highway. My fenders at OEM size were already doing that and it caused them to crack from the stress the tires were causing. Another thing to think about is your height you get in the rear. My fenders will not go all the way above my tires so having an extra 3/4's of an inch is enough to not smack one of these heavy wheels on the fender and cracking it.
Tires are another big things here... I am no expert but make sure when you get your tires that they are the least of your worries. I speak from experience in this department. I went with a 295/35/24, this didnt leave me much clearance in the front fenders. I had to push my camber adjusters in the top all the way in just to clear.
Bottom line... if you can accommodate all the hassles of 24s Rock em! Tubbing the firewall and stretching the fenders is just a pain. 22s are way easier I would assume!
