Does this offset seem right?
I have a chance to buy some Folger CUP4 wheels for my 87´vette.
The specs. are:
FRONT:10x17 offset 32 Tire: 265 / 40 ZR 17
REAR: 11,5x17 offset 41 Tire 315 / 35 ZR 17
Would these wheels sit nice on the car....

I believe those would be ok, they seem close enough to the stock 38mm offset. At least so close no one should be able to tell.

i havet really figured out how this offset thing is measured....Dosent the rim wide change the offset you need?
Would those wheels stick more out, or sit deeper in the fenders, than my stock 9.5" 87´wheels

Compared to stock 9.5" z51 wheels for your year, those wheels will stick out 1/2" more in front, and 9/10" more in rear. They rears should fit just the same as a 11" ZR1 wheel in back, and that's been done. They might have too much backspacing though, especially if you're lowered.
Keep in mind the Z51 wheels already stick out 1/4" more than the 8.5" base model ones.
Yes, both rim width and offset affect fitment.
What you REALLY want to know is "frontspacing" It's the distance from the mounting surface to the front face of the wheel.
Most wheel places tell you backspacing... which is the opposite. Backspacing only matters so that in that you can't exceed it or you rub.

The front tires will be 11mm closer to the fender edge. The rear tires will be 27mm closer to the fender edge. I'm assuming the stock wheel offset for a 87 Vette is 38mm and you have a 255mm wide tire.
To answer your question "Dosent the rim wide change the offset you need?" The wheel width has some effect on what offset is needed but the width of the tire is what really dictates the wheel width and offset needed to keep the tire from going past the fender edge on a car.
