Who is selling extended wheel studs for the 2015? Or are they just the 1/2x20s from the last generation?

I'm guessing no one has actually tried this to make sure it does indeed work, eh?
Paul is going the wrong way for an et on an 11" for the front. For an 11" to clear the strut body it would need to be around an et25 to 30 give or take. For example: a 10.5" et45 needs roughly a 10mm spacer to clear the strut making it effectively a 10.5" et35.

19X11's will work with offset struts, the issue isnt the spring perch, its the tube of the strut. Without wheel spacers you will not run a true square set up if the wheels are different offsets.

Rehagan Racing sells ARP studs as well as Cortex, they also sell offset coil overs. I don't know why anyone would invest in coil overs that were not offset but that's just me.

I don't need a true square setup when it comes to the wheels, just the tires. I don't have a problem having them rebalanced/remounted/etc., to rotate them. So a different offset up front wouldn't be an issue as long as I can do an 11" rim and run a 305. If going down to a 30 makes it work, I'm willing to go that way. I'm not completely against switching over to a coil over system, by any means - but figured it would be easier to snag the wheels/tires first, if possible.

Ok, thanks for the help but I've gotten a bit lost in this discussion.

I want to run a 19x11 Forgestar CF10 with a 305/30x19 tire. This will be for front and back.

Assuming I've got the Cortex Racing offset coil over struts and I'm running the Brembo 380mm 6 piston brakes, what offset will I need to clear brakes, fit in fender and clear strut, and which end will need spacers?

Thanks, car is a track day toy and I want to be able to rotate wheels front to back.

Anybody figured this out, or will I be the first?

Plimmer, we've got the specs for that wheel. The only difference is we might be able to relax the front offset a little based on the extra room from the Cortex struts. I'll need to check the mounting pad diameter also, as I know on the 19" F14 style it will interfere with the inside of the caliper on 14" brakes, but I think it will clear on the larger brakes, or with the CF10 style.

Ok, thanks. Is you company Vorshlag? Send me your details and I'll call you. I'm in the process of relocating from Atlanta to San Antonio, so as soon as I'm settled in I want to start tearing my car apart.

Wouldn't fit at all if the offset isn't changed there isn't a 1/2" to go on the inside so in fact it would stick out 1 inch.
If the offset (distance from wheel CL to hub face) is unchanged, the width increase is indeed split between front and back, 50/50.

On the other hand, if the backset is unchanged, all the width increase goes to the outside.
