Hello guys I have a 99 silverado that I got a hell of a deal on it has the 5.3 20" rims and it's been lowered.... Really low my problem is this... I wanted to know how much of a drop I have on this truck by explaining what I can see and what I have... I know I have aftermarket upper and lower control arms with aftermarket springs now I don't know how low it is but I can tell you the tires I'm running are 245/35ZR20 and I can't even stick my pinky between the fender and tire.... ( does not have aftermarket spindles)..... now for the rear..... It has a monster welded notch on it a flip kit with bell tech 2" drop shackles that I put on myself.. I rolled the bed fenders cause I saw it was cutting into my tires when I would go over bumps but I can stick 2 fingers loosely between the bed and tires I want to lower it more in the rear to tuck alittle of the rim but I also wanted to know about the pinion shims what would you guys recommend for more of a drop on my truck? thank you guys for the help
