so, trying to understand in simple terms about wheel offsets.

Also, the wheel offsets vs the wheel ball bearing wear.

here is the definition for wheel offset.

"This is in relation to track width, but refers specifically to the wheels of the car. The more offset a pair of wheels has, the wider the track and overall width of the car will be. Most HPI sedan wheels are 0mm offset, meaning the edge of the wheel hub that comes in contact with the axle hex adapter is exactly in the middle of the wheel. Some of our sedan wheels (like the 3mm Offset Mesh and Super Star wheels) feature an offset of 3mm, which widens the car a total of 6mm."

and some here

"Definition: Offset dictates how a wheel sits in relation to the hub. Factory wheel offset is determined by the location of the center line of the wheel bearings. Many aftermarket wheels are designed for a specific look or style and may not adhere to the manufacturer's design. You've probably seen wheels that stick out past the vehicle's body (positive offset), and others where the center is nearly flush with the outer portion of the rim (negative offset). While they may have the look or style you desire they may also shorten wheel bearing life."

now, explain it to me the difference between 35mm to 48mm

 

REASONS FOR NEGATIVE OFFSET

* Less stress on lugs and steering linkage
* Keeps tires tucked under/into the fenderwells

REASONS FOR POSITIVE OFFSET

* Moves wheels away from vehicle i.e. tires rubbing frame
* Increases vehicle width-providing stability
* Some people prefer the "deep dish" look

nevermind, found my answer.

but if it's 48mm, the rims sticking out more than 38mm out of the fender, right?

 

so i guess 48mm is consider positive offset.

 

You can have either a positive or negative offset. Probably why most American wheel manufactures when dealing in a custom size just refer to back spacing(the distance from the back of the rim to the flange mount). Positive offset, like the Evo, is the flange is 38mm toward the outside from the centerline of the rim. If the rim your talking about has a 48mm positive offset it would move that flange 10mm farther out away from the centerline of the rim. This would actually bring the rim in 10mm closer under the fenders.

As far as wheel bearings, the farther out the more leverage/load put on the bearings. I don't think you'll own your car long enough to notice unless you stick some 22" steel 50lb wheels on her. Haha.
