Wheel Offset Guide, Unsure about proper offset? Look here first. Options

[WannabeGT4]

Ideal Offset in Relation to Wheel Width (standard ride height):
Width - Offset
7.0"-----30mm with 15mm spacer (effectively 15mm) *
7.5"-----31mm with 10mm spacer (effectively 21mm) *
8.0"-----33mm with 05mm spacer (effectively 28mm) *
8.5"-----35mm
9.0"-----42mm (probably too wide no matter what offset)

This will make the rim almost flush with the side of the body. These offsets and offset/spacer combos will prevent the "sucked in look" that the factory wheels have.

Ideal Offset in Relation to Wheel Width (lower ride height):
Width - Offset
7.0"-----36mm with 10mm spacer (effectively 26mm) *
7.5"-----33mm
8.0"-----40mm
8.5"-----46mm *
9.0"-----53mm (probably too wide no matter what offset)

The rim will sit just behind the fender. In order for the rims to tuck into the fender well on lowered cars the the rim must sit back into the wheel well by 11mm compared to the standard ride height offset recommendations.

* Clearance issues prevent the use of most rims with offsets lower than 30mm. The spacer will actually lower the offset and at the same time move the rim away from the offending components.
* 8.5" rims may or may not fit on lowered cars.

Offsets shown are positive.

Offset is measured from the wheels center line to the mounting surface.

Ok, to bring a very old thread back, I'm looking at a set of 18"x7.5" with a +48 offset. I'm sitting on Eibach pros with roughly a 1" drop. Will these cause clearance issues and will they be flush or sucked?
