Did you need to re align your wheels after the drop? Also people said that your tires will wear faster which I'm not sure how that makes sense but just trying to see what I need and don't need.
Yes, alignment is in order after you drop your car. Also, I forgot that you will need to check your driveshaft pinion angle when you lower the rear. Depending on how much you drop, you may need adjustable rear upper control arms to adjust pinion angle. Lot of little things you need to do to do this right.
