Just wondering how many notches would I need to lift my irs beetle to fit 215/75 r15. I was thinking one inner spline and one outer spline. What do you guys think?

You shouldn't have to raise the rear of the car at all to run those tyres. 31"s fit without rubbing if you have suitable offset rims. I run my car a few years at standard ride height, both as a swinger and IRS and had no rubbing at all.

If you are going to lift the car here is a handy chart to make it easy. As it says lower all you have to do is do the opposite. So swap the negatives to positives and vice versa.
