lowered 86

[obrut]

I lowered my truck last weekend. Its an 86 GMC C15 and I used belltech 3" drop spindles in the front plus cut one coil and upgraded to the 1.25" brakes at the same time. I did have to grind the front lower control arms to clear the stock 15x8 wheels. I do still get some rubbing when I turn full lock and when I go over a bump. I'm not sure how much I can grind on the control arms, anyone have pictures?

In the rear I used the brackets to flip the axle. I'm still running the stock shocks and I did not put shock extenders on in the rear. I removed the bump stops, the rubber piece and bracket from the frame but the rear seams rough when I go over bumps. Is this because of the shocks?

The front I removed just the bump stop rubber piece but the passenger side seems harsh when I go over a bump.

Would drop shocks help the ride when going over bumps? Should I do shocks or extenders or both?
