    Right now I have the Eibachs coils and 5100s set to "0". I want to raise it up to the .85 setting, but I'm on the fence about it. I was wondering people who run this setup need UCAs to get their alignment into spec, or if they're fine without them. If you have the actual alignment numbers, that'd be even better. I'm trying to avoid the $500-700 extra by all means. Any input would help and be greatly appreciated.

    i have them set at 0.85 on a 4x4dc. the dealership was able to keep them in spec. I don't have the actual numbers handy. they might not have been the optimal numbers according to chris4x4 but they are within factory limits.

    Homertaco grill, Light Racing UCA's, 2.8" front lift (5100's at 0.85 setting and Eibach springs) 2" AAL with rear 5100's, Wet Okole seat covers fr/ bk. 17 x 9 Incubus Crusher wheels w/ 4.5" backspacing. 30% tinted front windows.
    I had them without the UCA's for a couple months, and the best alignment numbers I could get were caster 1.9/ 2.08, camber 0.6, and toe 0.03 after a number of alignments. It drove okay, but felt light through the wheel, and I got tired of it. Put on some Light Racing UCA's a couple weeks ago, and have caster 2.5, camber 0, and 0.01 toe, and it's perfect now. I even noticed that the little vibe I had at 60 km/h has disappeared?! I say that if you go any higher then 2-2.25" that you will need UCA's. Alignment places, and other people may say that it's in "spec" but is that really the best? The specs are to wide of a range. It's up to you really...
