Of course itll work. x9 at et 15 is 6mm's narrower on either side of the rim then 9.5 et 15

Btw zoomzoom. Any particular reason why your only doing x9/x10? The car can fit more easy with the correct offsets and your intended camber settings. Also i prefer square wheel/tire sizes over stagger on the 370low for track

I run around -2.6 in the front.

I wouldn't run +15 on offset (20mm spacer?) though, unless there's a reason to?

If I understand correctly, the 18x9.5 +35 should clear just fine according to your data, so why run a spacer that would create clearance issues?

You ran a 275/35 up front with no issues? That definitely simplifies things.

I run with RPF1 18'' 9.5 +15 square setup on a 275 tire.

the rear is perfect and the front you will need to run with a lot of camber or narrow tire.
I had to roll my front fender to make sure it doesnt rub !

they clear my AP BBK.

the +38 in 9.5'' didnt clear the caliper

edit;
-2.7 camber

Rules limit, those are the max.

I used it as a test, 9.5 et15 is the same outside clearance as 10.5 et28 which is what i run now up front because i verified the offset clearance with the 9.5 et15 . Now i run 285/35/18 with 10.5 up front

Fair enough
