Thanks...

Your S2000 will look like a swamp buggy.

i dont really understand how the offset works, so the Higher the OFFSET the wheels is more pushed in and the LOWER the offset the more the rims will STICK OUT?

Thanks in advance

Correct.
You need about a 55mm offset for those fronts you listed and about 65 for the rears you listed. You're about 30mm shy on the rear. That's over an inch further out than stock. If you think that will "fill out" your wheel wells to your liking, then give it a try.

Call me a newbie on offset, but here is my question on it...

Correct me if I'm wrong, but I thought that the bigger the offset, the more it's gonna stick out, since offset is the distance between the wheel and the mounting plate.

And say that I want to stay with stock offset(rear, 16 X 7.5 +65), does that mean that I have to get a wheel that has the same or lower offset, considering that I can purchase spacer to increase the offset? And does the width have any effect on the offset? Say.....17 X 10 +65 (let's say it exist)??

wait....I think I just have the whole idea wrong.....

You have it backwards.

The bigger the offset number, the more the outer face of the rim/tire goes INTO the car (less sticking out).

The distance between the mounting surface of the wheel hub and the inside surface of the rim is ZERO. That's because it's flush. OFFSET, is the deflection of the inside mating plane of the rim from midline.

A spacer doesn't "increase" offset. It DECREASES the offset and makes the wheel stick out further.

Let's take you example of "17 X 10 +65" and compare it to the stock rim sizing of "17 X 8.5 +65". Since the offset is the same but you are increasing the rim width by 1.5 inches, half of this sticks to the inside and half of it sticks to the outside. In other words the rim will stick out 0.75" further than the stock rim.

How do I know what kind of offset my rims have?

xviper,

There is always one thing I can say about you.......

YOU THE MAN!!!!!

This is a real tough one. Unless you have it stamped someplace on the rim itself or from the specs off the website of the rim manufacturer, you'll never know exactly. However, you can get a rough estimate if you are willing to do a little measuring.
1. Put one of your rims front face down onto a flat surface. Be careful not to scratch it. Put it on a piece of flat cardboard.

2. Now lay a straight-edge (like a yardstick) across the top surface of the rim (or tire if you have a tire on it).

3. Measure the distance from the ground (or cardboard) to the underside of the straight-edge.

4. Divide this measurement by 2. Now you have the "mid-line" measurement of the rim.

5. Now put a shorter straight-edge across the flat mounting surface of the inner rim (where the wheel touches the hub when bolted onto the car).

6. Measure the distance from the ground to the underside of this straight-edge.

7. Take your "mid-line" number and subtract the number you got in #6. If it's positive, you have a +XX offset. If the number is negative, you have a -XX offset.

It doesn't matter if you have a tire on or not as long as the tire doesn't have a bubble in it where you put the straight-edge. All you want is the "mid-line" number to start with.
