Does anyone know what the widest wheel we can fit in the back of the S650 is?

[roket]

Many thanks!
it all makes sense with the new numbers now.
Not sure why my wheel vendor says my wheel choice would hit the strut.
Looking at
19x9.5 +38
19x10.5 +32

yeah, not sure why they're saying that. however, i can only promise that fits on a Dark Horse, as GT suspension could be (but probably isnt) different
here's a comparison of your setup vs mine, assuming you will have 275/30R19 front tires, and 315/30R19 rear tires, the widest that can fit on those wheels. orange is yours, green is mine

front fitment is gonna be fine, but do note that you will have a bit of rear poke
here's the tool i used for this

Thanks.
I have a cousin with the wheel specs im looking to get, so i can check fitment prior to buying.
The work wheels I want are 6 months till shipment.

Here's what I did...Project 6GR 19x10/11 with 285/30 and 325/30.

Car and wheels look amazing! Well done! Ceramic coating?

Yes, thank you! Had ceramic on the entire car and a ceramic-coated PPF on the entire front end.

I found a 20 x 11.5 wheel I like but could go to a 20 x 11.0 if need be. I'm wondering if the 11.5 would stick out of the wheel well too much as well. I don't care if it sticks out some at the bottom of the wheel well but I don't want it to stick out at the top of the wheel well. I'm pretty sure the Dark Horse wheels are 11.0 wide. Dark Horse pictures below for reference. I'm just looking for as much grip as possible out of the hole. Maybe I would be better going with a 19 x 11.0 or 19 x 11.5 and just use a taller tire if that is my goal.

Widest we have ran is a 19x11.5 with a 325/30/19 but it does have a slight poke. Camber adjustments could help tuck from the top

What’s ur offsets??? Im looking to do 19s as well. I would like to run a 315 on the rear.

Widest we run with no rubbing issues is a 11.5 rear with 325/30/19

@Project6GR Wheels could tell you for sure. But 315 is slightly narrower than mine, and I don't have any issues with rubbing or alignment or anything. And the look is magnificent. Handling is excellent. Wider tires transmit a little more road though, never mind lower profile as well.

Go big or stay home..

Going to try a 325 next?

Mine are already 325/30/19. Love the wheels and the tires.

19X12", +46mm, 355/30R19

Woof, woof woof! 355 on the rear! Spectacular. Now I'd like to see her lowered and some negative camber dialed in. I doubt there is any room on the inside for that?

 

[ThreePedalPlow]

not sure, but i can say it's definitely less than 5mm. it seems like the most backspacing for the S650 is 6.94" front, 8.31" rear without getting recklessly close to the shock/strut

So if I understand wheels correctly your setup with a 12" width places the centerline at 6". The +46mm ( 1.811 inch ) offset means your setup has a 7.811 inch backspace? Looking into your wheel well do you think you would still have clearance if you were running 20 inch rims or would you start hitting something else height wise? I'm hoping to run a 325/35/20 so I'm thinking that would stick up into the wheel well about 0.79" inches more than what you are doing based on the difference in overall tire height divided by 2 as shown below. If I stepped down to a 30 on the sidewall I think my tire would stick up into the wheel well only about 0.15 inches more based on the same formula. The two shots below are what you are running vs the two options I'm thinking about running. Let me know your thoughts pretty please.

i could not run 20s with a 30 series sidewall. i can barely run the sidewall i have

Apparently the overall tire height difference between 355/30/19 and 325/30/20 is only 0.3" inches and only 1/2 of that would extend upward into the wheel well. Is the top of your tire about to hit the shock mount or like 1/8 inch away from hitting it or something? I'm not sure what the first thing to hit height wise would be. I'm just guessing.
