I should note that I was never unhappy with the ride the Rancho coils provided. That said, after installing my winch, my front end sagged enough to make the Ohlins not work as well as they had without it. As in, they didn't have enough up travel to effectively use the bump zones or at least, not without having to crank up the firmness. Needless to say, I either needed to install spacers or test out new coils.
That said and what I can tell you so far is that the Rancho coils are much taller than the EVO's. It took some effort to install and remove them where as the EVO coils had a lot of room to spare. I was told by EVO that their coils should be firmer and so far, they do seem to offer about the same amount of ride height as the Rancho's. Unfortunately, I went ahead and installed the 3" bump stop extensions that came with the kit but they are robbing about 2" of up travel on my shocks so, I'll be removing them today and swapping in the 1.5" Synergy extensions back in. Of course, this is all because of the stupid tall 392 bump towers.
Hoping to get some ride testing in soon and yes, re-gaining some lost power would be very nice
