Looking at running the sway bar through the k member. This may not be a good idea -
I tried to find better spacers on eBay and came up with these -
Not tall enough, but with 3 of those QA1 spacers I bet it would work. No idea if the holes line up or not.
The StreetRays ad warns that "any lift over 2" will cause the OE swaybar to be "out of position" and thus can't flex / function properly."
Putting the sway bar through the K member raises it 2" or close to it. I'm no expert but it seems like that would have to affect the performance of the bar.
I'm leaning towards putting the bar under the k member and leaving the ride height stock for now, just to establish a baseline for how things work when they're "right."
Come to think of it, if I really wanted to put the sway bar through the k member, the right way to do it would be to remove the QA1 mounts, flip them, and weld them back on.
