Need help understanding offset
I have been looking for new wheels for a while now. I searched all the gallery threads and kinda have an idea of what i want. My problem right now is i don't fully understand how wheel offset works. I know our cars are +42 stock. Im on stock ex steelies dropped on Blues/Sportlines and have a slight tuck and don't wanna get anything that wont fit. All of the rims i see have around a +20 +25 offset. Can anyone tell me if these will fit or how to make them fit? I have a white em2 and was looking towards the XXR 522 or something similar. I like the white/gold combo but cant find anything with a higher offset. Where do you guys buy your wheels from?

Re: Need help understanding offset
here's some info from http://www.tirerack.com/wheels/tech/...jsp?techid=101
"The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one
of three types (measured in millimeters).*
Zero Offset
The hub mounting surface is even with the centerline of the wheel.
Positive
The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.
Negative
The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.
If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly. We have test fitted thousands of different vehicles for proper fitment. Our extensive database allows our sales staff to offer you the perfect fit for your vehicle.
*Backspacing, similar to offset, is the distance from the hub mounting surface to the inside lip of the wheel (measured in inches)."

also, tire rack would automatically not show any wheels that does not fit if you input your car. (lowering notwithstanding, for stock cars, though)
