Just had MM IRS bushings, Steeda differential bushings, Eibach Pro-Kit springs and MM caster camber plates installed along with a four wheel alignment and the difference is night and day. Went on a cruise to about 120 and instead of the stock feel of the car getting light, it felt like it hunkered down on the road. Handling is much more responsive, and the back end does not come out in the corners now like it used to on every cloverleaf entrance or exit. Haven't tried a strong launch to check the hop, but that's next. Highly recommended for anyone not wanting to go for the expense of a complete coil over. You won't be disappointed.
