Yes you NEED to get it re-aligned! I did the eyeball alignment on mine just to move it around but it needs to be done the right way. I had to adjust the tie rods quite a bit. If you didn't adjust anything your front tires will be toed in a LOT. I should have mentioned something to you before, the steering geometry is a lot different with the newer spindles which is why the tie rods need to come out, and you may also need to compensate for bumpsteer since your car is lowered a lot (I know very little about bumpsteer though so someone else would have to help you with that). Which year spindles did you end up using?
