Wheel 18 vs.17 vs. 16
#2
well if you want more speed, go w/ ultralight 16s but if you are going for cornering ability, defenitely go w/ 18s with grippy tires (nittos, toyo proxie t1s, kumho's etc. etc. etc.)...the lighter, the faster your car will go but the bigger the wheel, the better the car will handle (upto a certain point of course)...i've heard that the bigger the wheel the worse u-turn radius you get, though...i'm pissed about mine, i have a stock se w/ my stock 17s my u-turn is right around 40 feet whereas a stock maxima w/ the stock 16s u-turn is right around 32 feet...thats almost a full lane difference

For pure performance in handling, 18" rims would be the choice. But keep in mind, the larger the rim, the heavier it can potentially be. In my opinion, 17" wheels are a good choice for overall performance. You can get a set of light 17" by 7.5" rims and put some 235/45/17 tires on them. Also, if you hit a pothole with an 18" rim, you could be looking at some damage. At least with 17's you won't feel like you are running on rubber bands.

can i go 17x8 or is that 2 wide?

Go here and enter your measurements:

Use 225/50 17 as stock and 245/45 17 as new... it's .6851400730815917% too fast
Play around and see what you get.

16" owners 235/45R17 will fit your application w/o affecting your speedo readings. 215/55R16
DO the Math and See for yourself.
(25.4mm = 1")
I found out the hard way.

In terms of speed (accelerations in particular), I would imagine that a small uniform wheel (ie.. 16 non aluminum), would give you the best performance..
Why... the Moment of Inertia for an 18" aluminum wheel is MUCH greater than for a 16" non-aluminum wheel. The lower the moment of inertia, the less energy it takes to get it spinning..!!!

No, he meant "moment of inertia." That is basically the torque required to give a certain wheel a certain angular acceleration. It increases with the square of the radius of the wheel. A 20" inch rim would take 4 times the torque to accelerate than a 10" rim...all other things being equal (which they always are in class, but never are in life).
It's all right here:

Exactly what he said!!! But i'm just not sure how much of a difference one would see between a 16" and 17" wheel...
Just thought I should mention it for completeness...
Maybe if you have a 18" chrome wheel compared opposed to a 15" hub-cap!!

I have 16" alloy-alluminum rims that are the 9 spokes fron the factory. I am thinking about putting some more tires on them cause factory tires spin to much when you floor it. What would be the recommended tires to get? would it be ok to get a tire size of 16 x 8 instead of the stock tire size of 16 X 6.? Would light 16's be faster than 17's?

I don't quite understand your question, but will try to answer what I think you asked...
Stock 16" wheels are 16x6.5". My 4th gen SE wheels are the same dimension, and I have 225-50-16's on them. They fit but bulge a bit...the rim is a little too skinny, but the tires do fit. You could fit 225-50-16's on yours as well, I have no doubt. The optimal rim width for that size tire is 16x7.5 or 16x8. 16x8's would be perfectly flush with the side of the tire, no bulge at all. That's the size I would target if I were getting new 16" rims.
