rear upper and lower control arms
rear upper and lower control arms Getting close to swapping in the 6.0 into my fox body. Got the 8.8 built with strange stuff. For a strip and street car.....do adjustable upper and lower control arms in the rear? Just uppers? Lowers? I've been told I don't need them and I've been told I do. Looking at team z and upr in whichever ones I go with.

Non adjustable lowers and adjustable uppers is what I would do, and what I did when I had a dedicated fox drag car circa 15 years ago.
I had UPR uppers and spherical bearings with Maximum Motorsports lowers which were not length adjustable, but were ride height adjustable.
However, if you don't go to the drag strip much or if you don't know how to adjust them, there is no advantage to adjustable uppers.
edit - and when my old Mustang was stock with a 175 shot, it short timed in the mid 1.5x's on a completely stock front and rear suspension and 275 50 15 drag radials. So assuming you need those control arms and adjust-ability for hooking up with typical street car power isn't always the case.
