Should I install a 1/4 inch spacer on driver side?

I’m getting the eibach 2inch lift kit installed on Wednesday, along with a single 1.5 AAL. Some posts I have read mention they get the “taco lean” after lifting the truck. Should I proactively have the 1/4 spacer added to the driver side? I want to get this right to first time.

 

Investing in a set of adjustable coilovers would be getting it right as they can be set to compensate for the lean. Adding a spacer to an existing non adjustable coilover will limit its performance...be better off leaving it as is because performance is better than looks in this situation.
