Still confused on rim offset...

[Chaotic Bliss]

I was wondering if anyone has an accurate answer as to what offset is required on a 18x9 or 18x9.5 rim so it will fit properly on the 05 without sticking out? Has anyone bought some aftermarket rims yet and has this info?
I couldn't find a definitive answer when I searched.

I will be getting my car next month and want to start checking out different rims.

Thanks

the offset for the 05 is 45mm!!!!!!!!

Ya but does that mean it is the same for an 18" rim? Even if the rim is wider then stock?

offset must be 45mm no matter what size the rim as far as i have read!! i believe it measures how far set back the wheel is
