Offset for 88 325ix?

[88325ix]

My wife's 88 325ix is in need of two new wheels to replace the two bent one's currently on there. The style of the existing wheel is the "basketweaver" design (15", 4-lug) Question: if I'm out shopping on eBay, and elsewhere, for these, what offset am I looking for for a 325ix? And Jim, does the Tire Rack carry these? (I'm trying to paste in a link with a pic with no success, so I hope you know the style I'm speaking of).



Thanks.

Regular E30's are in the 30-35mm range, but I believe the iX runs around 40-45mm offset, close to many front-drive wheels.
