how could the rubi disco limit your droop?
when disco'd the 2 halves free spin from each other
It does, often significantly. Ive seen many examples of it Before vs after on the club RTI ramp days. With lifts sold by the beloved vendors on this site with their recommended link size.
Its more than just being physically connected to the axle, the links themselves bind, and longer links with flexy lifts and big fat tires seem to suffer badly. I have seen, in person several times, links bend over the draglink while turning at full flex, and lots of tire rubbing. If the links are making contact, limited droop is just what happens prior to bending or breaking the links. The first time you see e-disco links flip, youll say "WTF", as short links like to do that.
Drive up a makeshift RTI ramp till a tire comes off the ground using the factory set-up and mark your progress, then physically disco the links and do it again. Thats the only way to tell if your set-up is being limited by the e-disco.
Plus, the e disco is not a very robust unit and is very prone to breakage.
I have had similar experiences with the antirock, so don't drink that coolaid either. I put one on my TJ, felt no more stable on the trail than before and lost 4" of droop, and it was way less effective on the road than the factory sway bar was. Then I put one in the rear of my JK when I had to cut the factory off to make room for coilovers, It killed about 5" of flex and was no more stable than running no sway bar in the rear - so I removed it and have no rear SB.
