I'm running the Aluma series coilovers. Put them on in December.
Normal highway driving and cruising is like night and day. Body roll is cut significantly. Nose dive is gone. Twisting through the mountains at 75 MPH feels fantastic, whereas it would have been downright scary before. I would have done this for the highway driving experience alone.
I have had the rig offroad several times since installing, but not enough to give a full review due to the time of year I purchased them. Most trails are still closed or impassable due to snow where I typically go. I will say that they have performed great when I have gotten it out there. It doesn't soak up 100% of bumps while doing 40+ MPH on washboard roads, so don't expect anything like that. But it has been as good as I hoped for.
