Mags and offset question

[gatty]

hey guys,

I own a non turbo R33 - i know it's a four stud pattearn and i've been told has a offset of about 114, but I haven't measured it accurately yet etc...

my question is would these rims fit on:

I think they aint bad look - 4 stud pattearn but lists a offset of 100mm - forget about these??

[gatty]

i just had a go at measureing offset with tape measure (not real acurate) but measured them @ 80mm apart - WTF?

[boj01]

are you sure its not stud pattern of 114.3.........as +114 offset isnt possible

[Evo_Lee]

Right R33 have 114.3mm PCD and largest offsets are usually +48mm.

ahh, thats what i eman

what is the offset anyways?

i am refering to stud pattearn sorry...

[browny]

Offset refers to the where the mounting surface is in relation to the centreline of the wheel.

Using different offsets will change your wheel track. Your states registration authority will most likely have some regulations on wheel track changes (ie in NSW you are allowed a max change of +25mm overall). The easiest way to avoid problems is to have the wheel made with the same offset as the std wheels. If they are a reputable wheel supplier should do this (if not already part of their range).

An auto engineer I was talking to said wheels are the No.1 problem he finds on cars, and most of the time the owner isn't even aware of the problem. It's easy to get wrong, but it's also easy to get right.

Why don't you ring them up and ask what the deal is.
