Wheel Offset Guide

[N1GTR]

A quick guide to understanding Rim Offset / wheel offset for those of you buying some new rims for your cars, as the wrong offset can make a set of rims either not fit at all, or just not give you the right look Its all pretty simple, and the pic should be a huge help

...and...

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.

ZERO OFFSET

The hub mounting surface is even with the centerline of the wheel.

POSITIVE OFFSET

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 OFFSET

The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.

Something that is also very useful is the offset calculator. Give you a measurement of the difference between your current wheels and your new rims. Will help you work out if those new rims will fit - clicky

the offset guide link is dead, and that calculator asks for a username and password.

anyone have newer links and/or details for these resources?

Does anyone have any good pics of an R33 GTSt with 18x9.5 +17 all round?

[God_speed]

Just as important as the offset is the disk type for some Japanese rims, or just the clearance for rims in general - make sure the spokes clear the brake calipers before you pay for them.

Made an expensive mistake in ordering Volk GT-Cs which arrived with a B-disk type which didn't clear the stock Brembos on the front of my R33 GTR.

D'oh!

might be a stupid question, but is it possible to modify the offset of a wheel safely or at all??

[boiracer]

cool, but what is the standard offset on a r33 gts-t??? its hard to use the calculator without knowing that first.

yes offset can be added with adaptors, but last i checked theyre illegal in aust (well QLD atleast)

[boiracer]

adaptors??? i meant spacers

def spacers are the easiest bet and cheaper if you have already brought rims.

[joeyjoejoejuniorshabadoo]
