Looks like the length of the track bar is preventing it from dropping any further. If it was 3/4" longer it would let the axle drop to the bottom of the shocks. Does this qualify as "binding?" (I'm not actually sure what TB binding is.
I'll give this thread a go and see where it should be, since I wasn't the one who installed it. I'm waiting for a Savvy GTS in 2 weeks, so I won't be on the wheels for a little while.
It says that being a little off is ok. Is 3/4" considered "a little?" is it cool if I extend it, see if it hits anything badly at full tuck, and if it doesn't, just call it a day.
