It really won;t help your handling at all, if anything it may be a detriment. When you put springs on stock struts, the struts won't perform as well, due to the fact that you changed the geometry slightly, not to mention the valving on the stock strut was meant for a longer spring.
for 1/2 - 3/4 of an inch, I wouldn't even waste the money. I'm not even sure you'd notice a visual difference with that shallow of a drop.
Sucks about your drive way.........try moving.....jk
Later, good luck,
