I'd love to go to leaf springs as my 95 yj was awesome with its budget procomp 4" lift leafs, but that's not going to happen.
Custom coils or coil over shocks would be another great option, but it not happening anytime soon.
So, after that input, I’m back to standard off the shelf coils. 95% of the time this thing will be going from home to work/school and back. The other is random outings. I really just want a set a coils that will handle a hard weekend occasionally. The TeraFlex I have are not fitting the bill and I know 90% of that is from their age.
My conclusion from everyone's awesome input:
Add another inch of bump stop ext (3") to the rear
Stick with 4" coils
Stay away from Transamerica/McCoy Bro coils
My budget for next month is $500-600. I'm going front and rear coils, coil pads, and hopefully new rear shocks. I put the Bilstein 5100 back on even though one is leaking, but the YJ ones I got from sharpmanx where almost non-existent from the YJ valving. Adjustable pads seem good for settling, but I'll wait and see how bad I need them after this upgrade.
After next year, once I get into a house, I'll be looking at getting a "long arm" lift with a tummy tuck skid and fox or king shocks. I'm thinking I'll be dropping $4-6k.
