I'm going to say wait and buy the Ground Controls. I've never felt the ride with the H&R's but I can tell you from experience that the Ground Control/Koni setup was even more comfortable than my stock setup. Plus, I had the ability to adjust my suspension to an even height anywhere from 0-3" unlike regular springs where the drop is inconsistent and can leave your car uneven. I'm not saying H&R is bad, I've only heard good things about it, but I think you would like the Ground Controls a lot more.
