Default '05 STi, 8.5x17, 255-40-17, wheels that work?

I have spent many hours researching for a set of summer wheels and tires and have decided on 8.5x17 with 255-40-17. It appears that several of you are running this combo on the '05 STi with no rubbing etc. I have the impression that these sizes *should* work on a stock '05 STi w/o any fender modifications. However, I am having a tough time finding wheels that are *confirmed* to work (FAQ only lists two). Here's what I've found so far via searching that people have reported:

'05 STi, SSR Competition SSR Competition, 15.3 lbs
SSR Competition = 17x8.5_ET48

(Response from "2phless" at NASIOC)

'04 STi, Rota Slipstream Rota Slipstream = 17x8.5_ET48, 21 lbs
http://forums.nasioc.com/forums/show...&highlight=255

'04 STi, Rota Slipstream, 17x8.5 ET48, fenders rolled

'04 STi, Enkei ES-Tarmac, 17x8.5 ET48, coilovers etc.
http://forums.nasioc.com/forums/show...&highlight=255
14.8 lbs in 17x7.5

'05 STi, Volk CE28N, 17x8.5 ET50, cusco4life (at NASIOC and IWSTI) confirms that these clear the Brembos with no problems, running Falken Azenis RT-615 with 255-40-17 (he emailed me), NO RUBBING ISSUES:
(cusco4life's thread on NASIOC)
(cusco4life's thread on IWSTI)
(Mike at www.forperformance.com said this wheel will clear the Brembo calipers)
14.8 lbs in 17x9

'05 STi, Volk LE28N, 17x85. ET47 or ET50, no conclusive answer on whether this setup worked:
http://forums.nasioc.com/forums/show...&highlight=255

Although there are a number of other wheels out there that are in the offset range 48-50 in a 17x8.5, no hard data on whether they work with the STi (i.e., clear calipers). For example:

Volk Racing TE37 (+50 offset) 17.75 lbs in 17x7.5(found this, STiMonSTAR at iwsti.com confirms that he is now running 255-40-17 with stock springs and no rubbing)
(Preston at Gruppe-S says this wheel will clear the Brembo calipers)
Mauro Motorsports lists this wheel as clearing Brembo calipers

Gram Lights 57S (+50 offset) (found this)
(damnedhoodlum at iwrxsti.com says that these did fit but stick out a bit (probably because of +40 offset))

5Zigen ZN+ (+48 offset)
(Mike at forperformance.com says this will clear the Brembos)

Work XSA-02C (+47 offset)
(Jim at Work in Vista, CA says they will clear the Brembo brakes; MSRP: $480/wheel)

Work Meister S2R (+48 offset max available)
(Jim at Work in Vista, CA says they will clear the Brembo brakes; MSRP: $550/wheel) 20.5 lbs in 17x9

Work VS-SS (Same as Meister S2R, but 3-piece rather than 2-piece)
(Jim at Work in Vista, CA says they will clear the Brembo brakes; MSRP: $710/wheel)

Work Termist TM1 (custom wheel, any offset up to +51)
(Jim at Work in Vista, CA says they will clear the Brembo brakes; MSRP: $460/wheel)

Advan RG-2 (+50 offset) (found this, fits '05, no tire information)
(Preston at Grupp-S says this wheel will clear the Brembo calipers)
Mauro Motorsports lists this wheel as clearing the Brembo calipers)

Fikse Wheels - custom 3-piece forged wheels in any offset. They said that all of their wheels will fit the STi in a 18x8.5, but no one has tried any 17x8.5 and they were not interested in doing a test fitting. MSRP for 17x8.5: $935 each. FM-5 weighs 16.0 lbs in 17x8.5

Kinesis Wheels - custom 3-piece forged wheels in (nearly) any offset. All 18x8.5" wheels will fit; I am working with them to test a 17x8.5" wheel. Models are K57, K17 and K27. K57 weighs 17.0 lbs in 17x8.5

Any of these confirmed to work? Any others I am missing? If I can get some more hard data on what options I actually have, I will have a much easier time making a decision.

What is the ideal offset: +48? +50?

Thanks,

Jeff

Factory ride heigth still? If not, camber adjustability will let them clear. I added cusco pillow tops to my rear teins to get the 255s to clear. They have all the clearance they need.

The fronts should fit fine at stock ride height. I'm down 1/2" and it only rubs very slightly on the plastic fenderwell under severe auto-x turn-ins. A little extra (-) camber

You linked shots of my 04 at the top of your post, and I have one in the suspension section about the camber. search "cusco tein pillowtop" and you should find it easily.

Thanks a bunch for your reply!

Yes, car is completely stock right now. I am considering two suspension upgrades - either Whiteline G4 coilovers or possibly the new Ohlins struts that Myles is researching. In the former case, car would not be lowered more than 10 mm (less than 1/2"). In the latter case, car would remain at stock height.

So if I understand your response correctly, clearance in the rear at factory ride height is already sufficient w/o camber adjustability? (I did read your thread on gaining rear camber adjustability w/ the teins)

How about the offset question - I know that brembo clearance determines the required offset for a particular wheel to be mounted, but it seems like for this app the tire clearing the suspension and rear fender lip really needs to control the chosen offset, then find wheels with that offset that fit over the Brembos. From what I have read, most people with this setup are running wheels with +48 or +50 offset. Sound ok?

Cheers,

Jeff

I updated the information in the first post to add new information on several wheels from Work, Volk and 5Zigen.

I also contacted Fikse - all of their 18" wheels will fit fine (custom offsets available), but they don't know whether any of their 17" sizes will fit and were not interested in doing a test fitting...

I am also working with Kinesis - will update when I have more info...

Added links to wheels (manufacturer or primary US Distributor web page whenever possible).

Added Fikse and Kinesis wheels.

Added as many wheel weights as I could find.

Edited first post to add info obtained from cusco4life via email on fitment. Specifically:

CE28N, 17x8.5, +50 mm offset, Falken Azenis RT-615 255-40-17 CLEARS THE CALIPERS AND NO RUBBING!
