[SCOTI]

My combo is 2.5" western chassis dropped spindles & 1 coil cut from the stock springs. It's prob equal to about a 5.5-6" front drop. I couldn't go anymore w/o removing the inner wheel tubs.

Since I don't have the combo your inquiring about, I can only tell about what info I learned while seeking answers to various questions. I believe the manufacturers of both don't recommend using their products in a combination because you would end up w/some severe tie-rod & a-arm angles.

Dropped a-arms affect the suspension geometry the same as cutting springs or installing shorter springs. The ride won't change because your just dropping the location of the spring seat, but the geometry changes. Now add in shorter springs & this exaggerates the effects. As for adding the spindles, my guess is you'll start having some interference issues w/the tie-rods/calipers & rim b.spacing.
