Hey guys,
Here is the spec of the new wheel that I'm planning to get.
AP1 OEM = 6.5@55 & 7.5@65
18x8Front +48mm w/ 225/40-18
18x9 Rear ++55mm w/ 245/35-18
Do you think it will work out from the OEM spec without rubbing after lowering the car around 1 finger space?
Please advice. Thanks!

What is going on with the scrub radius when these high offests are being used?
I think your question should have read, "What is going on with the scrub radius when these LOW offsets are being used?"
(Or am I off my rocker?

Not sure if anyone knows the maximum offsets that can be used. There are so few wheels with offsets high enough, much less too high.
The chart already lists the minimum offsets. The problem is that people don't read the Guide, even though it's there.
Not everyone has Excel, so that's not the best way to do it.
I'm in the process of re-writing the Guide, to be easier to read and use. I'll be posting it soon. It will be based on offset and tire width, because that's what really matters. Wheel width is secondary, and just needs to be chosen to fit a given tire. Also it's written in a FAQ format, with a Table of Contents, so people can quickly find their answers.

The effect of differing wheel width on our situation is so minor, we ignore it. It's generally the tread at the widest point that rubs, not the side wall. Because of this, wheel width has nearly zero effect. (Less than other factors such as alignment, ride height, etc, and we already ignore those for simplicity.)
Don't forget, offset is measured from center. So the change in wheel width does not move the tread surface of the tire in or out.
