Suspension pick up points

[240RR]

Hey....I THINK I know what I am doing but wanted some opinions over the weekend before I get back to my project next week.

Building a tube chassis 240z with 350z rear suspension. In general it is my understanding that I should maintain the OEM geometry and pickup points on the suspension. I am also locating the differential at the OEM height to maintain the proper half shaft angles according to the tire diameter.
So in effect I am just lowering the chassis and maintaining all original pickup points and geometry for the suspension and diff.
I know I may run into a slightly less than ideal angle for the driveshaft as initially it looks like it might run uphill an inch or so to the differential. But if I lower the diff then the halfshafts run at an improper angle.

Your diff is a fixed point. It wont be affected by pinion angle changes as the suspension moves. Will the "uphill" driveshaft have a negative effect?

Oh yeah....good point. I kinda think uphill is not preferred but something is gonna have to compromise....that or half shaft angle. This is not the first time this has been done...tons of road race cars with irs rear and low ride height. Just need to satisfy myself I am heading in the right direction before I get too much done.
