What offset would these wheels be with larger lips installed?

I have a set of BBS RF Et33 15 x 6.5 need some help. And I was wondering how I find out what my offset would be if I installed a larger lip. It currently has a .5" lip and I was going to go 1.5" lip. I was thinking the offset would not change but I wanted to make sure with some of the offset guru's on here.

For each half inch of lip gain you have to subtract 6.35mm off the offset. So since you'd be adding 1" of lip, you would subtract 12.7mm from the existing et33, giving you roughly 15x7.5 et20. Changing barrel sizes works the same way, except you would add the change to the offset rather than subtracting it.

Also, any interest in selling the wheels? ;)

Thanks E30SPDFRK this is the kind of reply I was hoping to get.

And at the moment I have no interest in selling the wheels.
