That's 350R measurements, yes they do poke which is normal. Because of the rear brakes several wheel designs have a hard time clearing the caliper face so getting as close to factory offset is difficult. My Forgestar CF5V's are a 61+ offset and they clear the rear brakes by about 2mm which is perfectly acceptable but it just gives you some perspective at how tight things are. The factory wheels don't clear by much either, I think it's about 1/2".
I understand that. The first set I purchased was the r spec witch is 11 and 11,5” rear. However I tried rectifying it with 11” for the rear. That is not r spec. 11” is truly the right size for 305s. Like JAJ said the difference has to be in the offset.

Oh no, I'm definitely on the same page as you. It's just finding the right wheel to work is honestly difficult. I'm with you, it's a real pain in the dick sometimes.

For sure. Pictures and videos help however it’s not until you mount and look that you really see what you got.

Are you saying that this picture is not with factory alignment?

About 95% confident that's with a degree or more negative camber. For reference, here's mine on 19x11 and Hoosier 315s at -2.5. Hoosier 315s are VERY wide tires.

So .. what is factory specs for alignment? For those of you that track, etc.. What do you change the alignment settings to? If you do change the settings.. what does that do to the handling and wheel fitment ? Thanks!

Completely stock alignment. Nothing but a wheel swap

I just asked my alignment guy to get it as close to fords track specks as he could, he got it right on
Front need camber bolts to do this, rear did not.

...and lowering springs. The tread of my 305's on R-Spec widths and offsets tuck in nicely with the extra added camber from the lowering springs in my mind.

Yeah, it's on springs. I stand corrected. Still don't think the wheels would stick out past the fender.

If you want I can custom build you a set of wheels with the offsets you want and the fitment you are after. No sense in buying wheels and hoping that they fit. Spend the money once and be done with a setup that is lighter and stronger than eh everything else you have dealt with.
