Hi Ed,
Just a data point, in case someone wanders by this thread in the future, as I PM'd you in response to your questions on my setup:
S4 front suspension on 80 Euro S chassis with stock rear 928 wheel spacers (21mm?) and fender flares, I have 9" back space Kinesis 18"x12" wheels and 335 tires.
Rear suspension with relocated lower mount (outside of control arm) with bolt on hub centric H&R 28mm wheel spacers and fender flares, same wheels and tires on front, allowing them to be located anywhere.
My recollection is that there could be some minor rubbing at low speeds in tight corners, but not likely to occur on the track.

Excellent thread !
I`m also planning on using non staggered wheels on my race car. I`ll go for Michelin`s 27/65-18 S7/P2C tires, and they recomend 11-12" rims. The data sheet says "Thread width 270" and "Section/Rim 296/11" Do you think that`s doable with standard GT fenders? And, I too would very much like to know your ET`s
Thanx !

Ok I have the information after some measuring.
Rims are 18x11 as stated.
Width is 11"
backspacing is 8.5"
Offset is 3" which equates to a 76.2mm offset.
This should hopefully help you out.
The company that made these is still in business and I know would be more than happy to make more of them however having them make them new will run $781.58 per wheel, so $3126.32. Now keep in mind that these rims only weight between 15-14 lbs according to my scales so that is alot of unsprung weight that can be removed from a track car! (I will probably drop 100lbs out of my car from my street tires just with the rims and tires)
their website is http://kodiakracingwheels.com/
Keep in mind though that I would NOT run these rims on the street, they will not be pot hole friendly!

Hey Colin
Thank you for that last bit of info! Say, do you have the order form from back when you ordered yours? It would be very nice to know what measurements works. And are you interested in selling your shells if you decide to reshell yours? PM me Thanx!

V8 Man, I actually didn't purchase these brand new, I got them slightly used from a fellow who used to own a 928 race car and he had them specifically made for the car. I did go to see about having the rears reshelled so that I wouldnt have to run spacers and it would run around $500/rim to have reshelled 
that is for both halves. When I increase the rim width I will probably only reshell the outside.
Ed, When I reshell the backspacing will remain the same but the offset will not. I will probably only reshell the outter halves of the rims. There is absolutely no need to change the inner shell other than to get a nice deep dish
Now the one thing which I have heard, but have yet to confirm is that one can use BBS halves on these rims, but the BBS halves are a fair bit heavier.

I was thinking of CCW in Daytona to get custom made wheels with the same offsets, but if they are more expensive I may consider Kodiak.Thanks again Colin.Now off to the megasquirt thread.Ed

CCW will be slightly cheaper but not by alot. You will save about $130 per wheel in an 11" width. 11 1/2" wheels are $750 each. You choose the offset.

Colin,Are your shock locations stock or did you move them?Stan is running 18X12 w/9" backspacing and still uses 28 & 21mm spacers.He also has modified shock mounts for KONI AD's.Do you have any turn radius limitations now and if not,will you with 18X12's? Thanks,Ed.

Ed,
I do not run any spacers up front, and have koni hypercoil setup. These will not work with stock spring sizes though. As to rubbing, they do alittle bit at max turn radius, but you would never see this on a track and the amount the interfere is very very small.
Increasing to 18X12 will require fender work I believe. I doubt that I could add anymore than a 1/4" on the outside of the front, and that could be just from wider rubber, as well adding another inch on the inside is simply going to decrease turning radius.
