In what way will it look stupid?
Because you will have a very wide track and skinny wheels. It will look silly.
But it's your car...do as you like.
You seem to have your heart on 35mm spacers.
I don't want the wheels sticking out, but as you can see from the photos, my wheels are tucked in quite a bit. We're only talking small margins between spacing them out by 15mm to 35mm?
20mm.
The width of the arch lip and more.
Do you want to do serious arch mods, or not?
You've been told what will fit on standard arches and what will not.
35mm spacers and 6.5" wide wheels will look silly...less so if you have 9" wider rear wheels.
If you want to run 35mm spacers, you WILL be doing SERIOUS arch mods. Rolled lips AND pulled arches...and you have to lose to lose the arch trims.
