Minimal operational clearance: Cross-member to ground?

[BANKO]

Thanks guys for all the great suggestions on other concerns.

1. jacking the car
2. oil pan clearance
3. header / exhaust routing
4. crowned roads

I'm looking to avoid this donk look (22s shown, I will run 20s):



The bigger concern I have is even if I run Speedtech upper and lower a-arms + dropped AFX spindles, I will get have some steep a-arm angles & possible ball joint bind if I can not raise the upper & lower a-arm mounting points to try to make the a-arm parallel to the ground.

This pic shows the cross member touching the ground w/ airbags deflated on another car and steep a-arm angles.
