Dropping the height with coil overs will require a realignment. But dropping it with drop spindles won't.
Sounds kinda stupid, but worn out front springs with a DA front shock will give you the ride height you want and the response you'll want. Most everyone seems to put new springs all around, and they always raise the ride height for several reasons, but the end result is the same - increased ride height.
I have a very decent front end setup due to a member here giving me a bunch of parts that he no longer needed (I'm very fortunate and appreciative.) A double adjustable shock will give you the same response as a coil over - I've had good luck and like the Vikings I have presently. But coil overs on all 4 corners is definitely a better option if you have the jing to give up for them. If you go with a front coil over, then weigh the car to see what spring you need on the coil overs. You will be able to find springs from 150 to 550 spring rate, and they are vastly different. I don't know much about a handling spec, but a straight line racing spring of 250-350 is plenty if you're carrying 1800-2000lbs on the front. But for road racing / cornering I have no idea what would be best.
