Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

For comparison, I am running the 10" SD in the rear with 15mm spacers, so yours will stick out another 12-13mm (1/2").

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I have a 99 911 2 narrow body that came with Sport design wheels (8" front / 10" rear). The car also has the PSS10 / Bilstein B16 suspension and is lowered a bit, but not extreme. Sorry, bought used, don't have settings details) Will these rims and tires fit? 8Jx18H2-ET57 (with 235/40Z R18) 11Jx18H2 ET 51 (with 295/35 ZR18) I know the answer may not be exact, but thanks for your feedback.

I found this website/calculator very helpful when exploring options for a wheel change. Plug in your current setup and compare it to your desired setup. https://www.willtheyfit.com

POST 3Original post

U will need some morr camber to get the rears to fit. Factory et is 63 on a 8x11.

POST 4Original post

Are you currently running spacers on your current Sport Designs? Assuming that you are not, the fronts will be fine, they will be tucked in 5mm more than your Sport design 8" fronts The rears will poke out 28mm more than the 10" sport designs For comparison, I am running the 10" SD in the rear with 15mm spacers, so yours will stick out another 12-13mm (1/2"). I am lowered about 1" from stock with H&R sport springs

POST 5Original post

OP - As De Jeeper and the others say, too much poke on rears. .1 would need rear wheel wells rolled and a good amount of camber to fit. An et63 11” fits on a mildly lowered suspension with -1.8ish camber.

POST 6Original post

Quotes source post: 20447153

Yes and I forgot to mention that my rear camber in the photo is set to -1.7

POST 7 / ORIGINAL POSTEROriginal post

That probably rules out these wheels/tires, but out of curiosity: The sport design wheels are on the window sticker so I would assume there are no spacers? Did the factory oem setup ever use spacers? Can the camber be set to -1.7 or -1.8 without swapping out parts? Thanks for all the great info.
