Also is there anyway to fine out the size of my current rims on my 370z?

umm well if you have the sport package they are 19" by 9 front 19" by 10 rear and if they are base they are 18" by 8 front 18" by 9 rear

the best imo is the 19in rays on the sports package

btw where is a good place to buy some rims? online or local shops?

Also i noticed ppl use different set of tires from front and back... and also the size are different as well... is this normal?

the Z comes standard with off set wheels, where the fronts are not as wide as the rears

Since no one has answered your question about the 19 x... I will.

Here is a sample description you will see in two variations:

Variation 1:
19 x 10 +22

In this variation the 19 stands for the diameter of the the wheel. The 10 stands for the wheel width in inches. The +22 is what we call the offset. An offset is the distance the back of the face is from the centerline of the wheel width in milimeters. I.e. For this example the wheel back face is 22mm towar the outside of the wheel width centerline.

Variation 2:
19 x 10 et22

This is exactly the same except instead of using a plus the letters et replace it. It means the exact same thing.

As far as cool wheels check out my picture albums I have a new set of Strasse Forged wheels going on this next week and there are a good bit of pictures in my album.

Like trip pointed out our cars come from the factor in a wheel width offset. The reason for this is to maximize grip on the line and in the corners. We also run a staggered or offset in tires to match the wheel stagger.

Just about anything from iForged!
