I ordered some RSR best-I coil overs for my 2014 is350 f sport, I plan on dropping 2” at the absolute max and I’m wondering if I may need additional suspension parts to get a proper alignment and even tire wear.

Also look for some front upper control arms that are adjustable as the camber on the front will be out.
Megan comes to mind as one brand.

 

I’ve heard some iffy reviews on Megan products, are they at least decent? I’m going with SPC for the rear camber arms but not sure if they make the front upper control arms
