Lateral grip: Optimize for wheel bump travel or shock stroke?

Context
Reverse trike on double-wishbone IFS with coilovers

Objective
Improve lateral grip
Decrease roll

Method
Reduce load transfer
-decrease CG
--lower ride height
Current static ground clearance: 6"
Target static ground clearance: 5"

Current static ground clearance of 6" - target static ground clearance of 5" = 1" drop @ wheel * 0.84375 motion ratio = 0.8" @ shock
Current 16" extended shock rides at 15.5" - 0.8" = 14.7" new shock ride

Replacing with a threaded body shock of the same 16" extended length (11" collapsed / 15.87" extended) gives:
15.87" extended - 11" collapsed = 4.87" usable stroke
14.7" - 11" = 3.8" bump / 4.87" usable = 75% bump
15.87" - 14.7" ride target = 1.2" droop / 4.87" usable = 25% droop

Replacing with an 18" shock (12" collapsed / 17.87" extended), travel would be limited by packaging to 17 1/8". However,
17.125" packaging - 12" collapsed = 5.125" usable stroke
14.7" - 12" = 2.7" bump / 5.125" usable = 52% bump
17.125" - 14.7" ride target = 2.5" droop / 5.125" usable = 48% droop

Does that look right?

What would you do for a 100% street performance vehicle: 3.8" bump : 1.2" droop, or 2.7" bump : 2.5" droop?
