Where is the tie-rod interfering - at the rim edge? or at the tire? you have dropped spindles then it would move the tie-rod end lower towards where the tire buldge is.I run 17x8 bullets with a 3/8" spacer & I could probably run no spacer when I install my 11 3/4" rotors. I currently run 10 3/4" rotors so I have a spacer. Any further with a spacer & I would have to raise my front end to clear the outer fender.My tie-rod end is at the same position as paulyv100.
