Level kit on top suspension kit

I have a 2011 Tacoma with a 6" Fabtech (photos in my profile) Im installing a 2.5" leveling kit with a 2" add-a-leaf in the back. My question is has anyone done this before? And if so, was there any issues? Any positive or negative feedback would be greatly appreciated! Thank you!!

 

Theres a bunch of people who have added up to 3" spacers on top of their 6" drop bracket lifts.

since the db lift preserves the CV angle, stacking the 3" lift on top of that is like running a spacer on a stock truck

though, you'll run into the same issues of CV boot wear and the possibility of breaking your shock should you wheel.
and, (From experience from riding in 9" lifted trucks) the ride is faaar from..."smooth"

and what are you running in the rear so far? blocks?
