If want to install the 911 Sport Design wheels:
Front 235/35/19 on an 8.5 inch wheel with 55 offset = +19 mm inside, and +19 mm outside increase.
Rear 305/30/19 on an 11.5 inch wheel with 67 offset = +57 mm inside and +19 mm outside
I assume that front might be okay, but I should install at least a 7 or 10 mm spacer.
For the rear I need at least 1.5 inch spacer that will leave (38mm - 57mm) about 19 mm closer to the strut.
My question is, can I use the size spacers as I've selected, or do I need to go bigger?

These are 6 mm closer to the strut than original rear wheels. |
ok, so on the rear you are at 67 - 38 = 29 offset w an 11.5" wheel. i am running a 40 offset w a 10" wheel. i got not much space between my wheel and my coilover, and not much space between my wheel and my fender lip (on a 275 wide tire).
difference in wheel width is 1.5" = .75" on each side = 19 mm wider on each side, but you are pushed out an additional 40-29 = 11 mm, which makes you 19 - 11 = 8 mm closer to the strut than me. i truly think i could not get 8 mm closer to my strut. my conclusion is that this is probably only possible with a 19" wheel which moves the inner lip 1/2" up and further away from the strut than an 18" wheel does.
on the outside, your wheel is 19 + 11 = 30 mm / 1.25" further out than me. i've got -2 camber on the back and couldn't fit an additional 1.25", so fitment would require more camber than i got (which appears to be the case in your photos) and prolly some rolling of the fenders (which appears to be the case in your situation).
good data points; thanks very much. 11" wheels are much easier to find, good to know how they can be made to fit.
