Not sure, but I think it'd be fine. As you pointed out, Nissan Mike has 6" of total lift and is running 33's. Looks like with 5" you'd be fine with 32s. Having owned a set, I'm sure you know how large the SSRs are for a 32 though, so that might be a different story.
On a side note, if you decide to go with a body lift, I have a 2" B.L. for sale. Bought it straight from AC and it's never been out of the box. If you're interested let me know.
