Rim Offset and Tyre Fitment Guide
 

Ok, In addition to the "anything about rims" thread, this one is dedicated solely to rim offset and tyre fitment.

Below is what is meant by "offset". You can see how offset affects clearance from both the strut and gaurds.

Googling "offset calculator" will probably lead you to websites telling you how you can pay less interest on your mortgage... So go here instead.

Standard rim offsets are:
MY94-97 +55mm offset

MY98-00 +53mm offset

MY02-04 STi +53mm offset

MY01-05 +55mm offset

MY06-07 STi +53mm offset

Forester XT +48mm offset


Post pics of your rims (on your car) and state the rim size, and offset, as well as the tyre size. Along with any other info that may help people choose rim size and styles.

I'd say this is about the perfect fitment and size for looks AND practicality.. If they were wider or offset further, I'd probably have to rely on some tyre stretch to get me by without rubbing, and this of course compromises grip.

I don't get any rubbing now, except for a slight amount on full lock in the front (on the plastic guard liners, not the guards), and none at all in the rear even with a loaded car.

Not much camber at all. Want more. But it handles incredibly well.

[b]Other Info:[/b] Rolled guards front and rear. Some rubbing in the back when pushed but i like rubbing.. Went with 215's as the slight tyre stretch tucks up under the guards. Tyre wall when properly inflated takes cornering loads fine.
Could go 225/40's but would need more camber or less low.
