Ordered 17x8s and 17x9s for the FC
Ok, I took the plunge and went for the wheels I wanted instead of waiting for some 17x9" F*rd wheels to fall into my lap. I already bought some 17x8" Mustang wheels, but they were a bargain and I can easily get my money out of them. These wheels are supposed to be reasonably light and are actually A-Tech wheels rebranded by America's Tire Co. $112 ea for the 8s and $115 for the 9s. Cheap! What's going to kill most people is the fact that I scored a set of 235/45R17 and 255/40R17 (Supra Turbo OE size) Potenza S-03s with less than 30 days use (customer ride sstisfaction return) for $120. I was in the right place at the right time and helped out a Bridgestone manager with a little internet connectivity problem he was having. So I'll have some good meats for the GTU project. A little fender rolling and we'll be styling! Gotta go put the hurt on the local Porsche club autocrossers!

28mm on the 17x8s and 17mm on the 17x9s as per the FC wheel fitment thread. My only concern at this point is the front tire rubbing the spring perch. I do not have coilovers yet, but if my RS-R race springs don't ship soon I'll be calling Ground Control. I already have KYB AGX dampers on the shelf.

Aww, crap. I was relying on this post from the FC wheel fitment thread:
So +27 on the rear will fit better. Ok, I'll call the wheel shop and have them change it!

17" x 9" +20mm offset (+15 to +30 will work) with 255/40/17 in back
I'm particularly interested in the 5Zigen FN01R-C wheels which I think just match these values.
Note: after further research, I have learned that RETed's wisdom of matching the tire width with the rim width is actually considered a very good theory on handling improvement and is recommended by some guy who wrote some book that I am too lazy to re-research right now. Let's not digress the thread with who it was, but just to say that, yes, it appears to be very solid advice indeed.

Hey i wanted to know if size 18x8 front with a 2 inch lip and 18x9 back with a 3 inch lip, with a 38 offset fit on my Fc. I dont have a wide body kit so was wandering if it would stick out or not.
Thanks.
Thanks.

I wish you guys would learn how offsets work and do the math yourself, or even read the pages and pages in the "Official FC Offset Thread", instead of cluttering this place with garbage.

The fc fitment thread rocks, read though it when you get a chance

FD rims are 8" wide, +50, and about the tightest you can go in the rears.
Extrapolating to a 9" wide rim, that shifts the offset to about +37.
Now, this is dependent on tire size (width), so adding 10mm off spacing should be able to handle 255, 265 tires no problem.

I redid my Rims page to make it a little bit easier to understand.
I also added a rear clearance table...

thats a serious option for autocrossers who wanna run 255's up front and 275's out back!
I might just do that!

especially look at the difference in offsets between the 9'' and 10'' size on your chart, there should only be a 12mm difference between the two.
nice of you to provide these guys with info, many thanks.

Thanx for catching that!

I test fitted a front wheel and it clears the spring fine, but I may need to roll the fender lip to make sure I have clearance there during suspension compression. Oh, the center cap does not fit! The hub pushed the center cap out as I put the wheel on the hub. This is a racing project so it's not that big a deal to me, but everyone should know if they buy these wheels the center cap won't fit on the front. America's Tire sent me the wrong hub centric rings and I just got the replacements 2 days ago. The car is a project and is currently outside so I didn't mount up more than the one wheel. If you want I can do one side and take some pictures.
