I'm still learning the variations of offsets, just when I think I've got it all figured out I learn more, the change from 9 width to 10.5 and the offset change eith the width chsnge is still confusing me

Funny I found this thread as I was just on the phone with vossen today asking the same questions about the same wheels and the same 10.5 all around and how did u make this work. This is going to be the set of wheels I'm gonna roll on while I figure out what custom wheels to roll on while the wife cools down after all the cash I dropped on the Z at GTM. Good luck on your quest bro, as I am not rolling any fenders or modifying the body to fit these wheels that agressive. If looks sweet thou, but that's what custom wheels are made for with more options in rim size and offsets. Let us know how it turns out

with 1 piece forged wheels and deep concave you will need a wider rim for structural integrity (simple terms)... You might want to follow the setup they went with on the 265... yes there are less tire options but it will meet your goal...

Since your going with a complete rectangle installation here is what your looking at. Your new methodologies will sit roughly 28mm+ out from your present front side rim installation... generally, individuals run a 9.5 +15 with a 255 front side. A 255 or 265 would be my kick off factor and this is going to rely on rim product as well.... . .

Couple guys who have 10.5 up front said their running 225 up front w obvious stretch. Is this necessary?! I'm running a 245 up front now on a 9 wheel, could I at the very least get away with a 245 on 10.5 if a stretch is necessary?

Car looks amazing but I wouldnt say that is "hardly" stretched lol.

Looks awesome Diego thanks! I'm going for the 25 offset, that's plenty more concave and it doesn't require to much messin around.
