The issue is mostly space. By going with the 2" coilovers, you are reducing the size of the coil and also the need for a whole extra tower for the shock. My plan with mods is always to be largely reversible, so the coilover tower can actually fit through the stock shock cutouts in the fenders. If I design it right, the tower on the driver side will incorporate the panhard mount as well. Been thinking this design out for 5 years. lol
Certainly cheaper to go used jeep stuff, but it also lacks the tunability. I will be able to change ride height pretty easily to compensate for lean, and if the spring wears out or I need more load capacity, the coil itself is about $70.
