Drop spindles and drop arms put the spring pocket too close to the ground. The pockets will scrape all the time.
The raised lower ball joint in addition to the heated coil puts the upper control arm in a raised position at ride height. This pulls the upper ball joint in towards the frame due to the arc of the arms swinging motion. (negative camber) The UCA cam bolts probably to not have enough adjustment to remove the negative camber.
If you drive the truck a lot, you will chew up tires fast because the small range of motion will push and pull the bottom of the tire in and out away from the frame an exaggerated amount.
I don't have dropped spindles, or heated coils. Its just the home made lower arms and cut coils. I'm not concerned with taking all the negative out, just in making it not tear up tires instantly. The toe is also incredibly out at this point as well. Like I said, the first thing im going to do is an actual alignment and notch the frame, from there this entire convo may be irrelivant depending on how it aligns. If it doesn't align well, or something looks unsafe, then iwill order 4" dropped arms and leave the cut coils in it.
