So the setup fit well indeed, thank you!
But I struggled a different issue: the shop found that 2 wheels were bent. It is impossible to visually see from outside, but they showed it to me on the machine: wheel doesn't spin straight. Now they want $150 per wheel to straighten them

Depends on what tire you choose too, most 245/40s a 9.5" is the widest wheel width that is recommended by most manufacturers, there may be a few 245s that aren't recommended so check first.

I am looking at Forgestar F14 wheels for my non-winter setup. The offsets can be custom so trying to figure out the best offset to avoid spacers.
I run KW coilovers on my sedan and will be running at 26.25 fender to floor.
My goals are a nice flush fitment, but not overly aggressive. Would like to avoid stretching tires, poking or running excessive negative camber (more than -2to2.2 or so). Would also like to avoid any fender work. Also fronts need to clear BBK of course.
I’m trying to play around with the calculator, came up with these rough numbers:
Fronts 19x9 +38 wrapped in 245/40/19 PSS tires
Rears 19x10 +39 wrapped in 275/35/19 PSS tires
How far off am I?

In back I'd run 19x10+43 on 285/35s
I was running 20x10 +45 on 295s and the fit was perfect, that 10+43 on 285s will give you a couple mm in from mine (and I'm at -1.0 camber) so I think you'll be real happy w/ that fitment. If you want to run real big in back you could bump your offset up to a +47 and run 295s but that's up to you.
Here's mine when I was on 295s, and also 26.25" all around

And now on 285s (everything else is the same)

You're dialed in pretty close, I'd run 19x9 +35 on 245/40 this will be a great fit but still fine lowered and running in spec camber

Fitment on your sedan looks great.
If I decided to go with 275s in the rear either (for cost or availability concerns vs the 285s) would you suggest I change that offset any?

You mentioned running Pilot Super Sports and they may run a bit wider vs. other 275s. Rochester runs PSS on his Vossen 19x10 +42 on 275/35/19s and he's real happy with the fit IIRC. Might shoot him a PM or check his build thread for specifics.
Hey all,
I'm having tire issues with my set up. Since my car is awd the light keeps flashing. I'm running a staggered set up 20x9 and 20x10.5. The tire sizes are 225/35 and 255/35. The best solution would be to get a 225/40 in the front but they don't make a tire that size.
What are my options other than taking the staggered wheels off?
