yeah with spindles you don't need alignment but with the spacer you need it. i put my spacer on and didn't get it aligned for a month and it took a heavy toll on my tires, wore them unevenly bad
hell yeah nice! if you did the 3.5 spindle and 1.5 inch spacer like i did then you should be fine. my upper a arm was at a decent angle
yea man they were worse than stock.. hate to say it but I told you they suck. if you like the looks of them then I think it would be worth it to put HIDs in them.
