Ideal tire size

Hi, I'm new on here so bear with me. I'm driving a 95 Integra LS and am considering a Greddy turbo kit in the future, or I might just stick with intake, headers, and exhaust. I've heard that the ideal tire size for my car is 205/40-45/16 so as not to stray to far away from stock diameter. But, imo 17"s do look better. So my first question is 16" or 17" which is more performance worthy? And my second question is, what would I need suspension wise to complete the setup? I'm planning on an Eibach prokit but I don't know what else would be needed. Would 17"s require more work (camber kits, etc)? No matter what setup, I would rather do it right and shell out the extra $ instead of doing it cheap and replacing my tires twice a year. I had a buddy who continuously wore out his cv joints due to a f***ed up setup. Any advice would be appreciated.

Also, what are your opinions on the Falken Ziex ZE-512? It seems to get good reviews on 1010tires.com and also is reasonably priced. I live in the Pac-NW so I need an all-season performance tire.

the falkens are good tires thats what i am running right now, but please dont be like everyone and keep there rims on in the winter, take them off and then you wont ruin them

For performance the difference between 16's & 17's is not much - the only thing to look for is wheel weight - the lighter the better. There would be a difference between 14's & 17's

Besides the Pro-kit you should upgrade to a better shock(KYB AGX - Koni Yellows - Tokico Illuminas) it doesn't require adjustable shocks, but why not? I love my Pro-kit with AGX's. You should not need a camber kit with those springs. You should also upgrade the upper strut mounts to poly bushings (Energy Suspension/Prothane)
Dont try to be cheap with suspensio parts, you'll be happier if you spend a few extra bucks for better parts.

How low is your buddies ride? I'm guessing he has more than 2 inches of drop.

I got a set of Falken Azenis Sports from my buddy for very cheap that I use for autocross racing - i love those tires - there not all season but the only Falken's I have exp. with. http://www.falkentire.com/html/index.htm
