I'm not sure how long this has been around but seems like an easy bolt-in strut replacement solution for a DD. Priced them out on RockAuto for a Grand Prix and the fronts are $66 each and the rears are $58 each.

RockAuto now offers FCS Strut Assemblies. Entirely new strut, spring, mounts, bellow, seats, and other components make these complete assemblies safer, faster, easier, and often less expensive to install than parts purchased individually. The FCS Strut Assembly is engineered to meet and exceed OE quality. The components and valving are designed specifically for each domestic or import car, truck, van, minivan or SUV application. The precisely calibrated valving combinations are individualized for each application to best achieve OE ride and feel.
Each unit is tested on key measures and manufactured using reliable designs and repeatable production methods. NOK seals, highly-polished chrome rod finish, high performance shock oil, and an OE-type piston ensure first-class quality for each unit.
Assembly Includes:
MacPherson Strut: With NOK seals, mirror-finished, hard-chrome piston rod, and Japanese oil (to ensure a great seal, long life and consistent damping over a wide range of temperatures).
Coil Spring: 20% of production factory-checked for OE compression levels. Electrostatic coating for optimal corrosion resistance.
Bearing Plate: From same supplier as Monroe. Endurance tested under extreme load to ensure optimal performance & long life.
Boot Kit & Bumper: Bumper molded from urethane rubber for long life. Absorbs harsh, damaging road impact and noise for quieter driving.
Upper Spring Seat: Absorbs harsh, damaging road impact and noise for quieter driving.
Upper and Lower Isolators: Ensures spring remains stable in all conditions.
Robust Brackets: Reinforced to ensure integrity and long life.
