Check out this link.

That should give you an idea of exactly how far in or out future wheel setups will sit in relation to what you're running now. You just need to input all the information and go from there. Your current wheels should have the sizing listed on the back of the wheel.

Since the offsets are are 41 mm front, 50 mm rear, does this mean (assuming same sized tires on all 4), that I can use 9mm spacers on the smaller wheels to get a zero offset? Assuming there is no clearance problem.

Or to create some inner clearance, can I use 14mm spacers on the smaller and 5mm on the larger to get zero offset and create 5mm inner clearance? Does this make sense? Are there spacers in various sizes like this?

No, that is not how wheel offsets work. Every wheel has its own offset. If you wanted a zero offset, you would need a 41mm spacer up front and 50mm spacer in the rear. The offset is not correlated between front or rear wheels.

The offset of the wheel is the distance from the mounting surface to the center line of the wheel.



Different cars require different widths and offsets. We recommend x8.5 ET35 front and x9.5 ET45 rear. The position of the wheel also will be determined by the width, so when calculating those things you need all the info you can find.

Perfect!

Do you think using these spacers should also increase the inner clearance on the fronts when the larger 8.5 inch wheel are in the front, with all 4 wheels having the same sized tire? If so, this seems to be a good squared set up for these wheels.

- same sized tires
- spacers to neutralize offset and increase inner clearance
- For Style 68 with offset

Just to clarify, I don't think a zero offset is actually what you're after haha. The 18-19mm spacers I mentioned in my previous post would work best. Having a zero offset simply implies that the mounting surface is directly in line with the center of the wheel. This does not mean it will actually fit on your car. You may want to do a bit more research on exactly what offset means and how wheel sizing correlates before you purchase spacers.
