Question 18x8 O.Z. Superleggera fitment issues?

I am just about to purchase some 18x8 O.Z. Superleggera from tirerack but I am not sure which of the two 18x8's listed is the right fitment for an 04 WRX sedan. I am tempted to buy the +48 offset because it is considerably cheaper but after reading the entire offset thread I am worried that this offset might rub with this wide of a wheel. My current suspension setup is all stock. Any information/opinions would be great.

Hmmm...I can't find offset specs for the SL WRX applications; how did you uncover that +48 spec? And, what's the alternative?

TireRack shows a silver 18x8 OZ SL in ET48 @ $285 each, and 2 different gold versions - an ET48 version @ $295 each and another ET51 version @ $350 each. If you click on "view wheel closeup" in the TireRack Upgrade Garage, you will be taken to a webpage showing the offset, weight, and detailed info on the manufacturing method - cast, forged, etc. The much more expensive - and heavy - 3-piece forged OZ SLIII is also an ET48 design - but @ $740 each I assume it is out of the running.

The gold ET51 version would be a great choice for wagon owners who do have some potential issues with rubbing when using an 18x8 ET48 wheel and 225/40x18 rubber - depending upon suspension choices, rear alignment and tire choice.

But since WReXPower has an '04 sedan he can choose to go with either the ET51 or ET48 versions and have no rubbing issues using any 225/40x18 tire that I'm aware of - unless you've somehow managed to lower the car in the rear by more than 2". the ET51 version may let you run wider tires than 225/40x18 without rubbing. I did a search and found several posts with people running 18x8 OZ SL's with 225/40x18 tires on sedans - as well as one who ran the ET51 version with 245/35x18 tires on a sedan without rubbing. unfortunately, the pictures are no longer visible -the posts are pretty old.

Thanks for replying. I have spent days pouring over information from searches and it yielded nothing but confusion. I think I am going to go ahead and purchase the cheaper O.Z. with the ET48. After reading your post it soothed my aprehension about any issues enough to buy the tires. When I get them on I will post some pics.

Most after-market wheels for the Subie will be made in the +42-48 range, which is fine, my +48 18X8.5's fit with room to spare. Now if it were a +38 you might issues...
