MOOG 5662 up front, stock SS springs out back with AirLift bags. And custom reverse lettering BFG tires
Maybe try spring insulators up top all around to get that extra 3/8 - 1/2" clearance before switching out the springs. How's your oil pan?
Here's a pic of what someone else did to accommodate the low rider clearance/rubbing issue.Oil pan is fine....but I have bent one crossmember and shattered a tail shaft housing off the tranny once before. Front currently has two twist-in knuckles to hold it up so I can turn. When I take them out it drops another 1/2-3/4" and wont turn on new wheels. On stocks and my old irocs would turn just fine. Offset on my asantis seems to be too far foward. I gave them numbers I wanted but of course they built what they know "works" for an impala. Stock impala yea but not a slammed one.
