I originally had a 3.5" RE SA SF lift on the jeep when I bought it. I don't remember ever getting the bumpstops to ever hit when flexing with the 3.5 lift but I did get the tires to hit the fenders. Then I switched out the 3.5" springs for 4.5" springs. I guess you will just have to see once you get the shorter springs.
What I meant was, why complete the TT and BL at the same time? Do the BL, then complete the TT sometime after that.
