I had a set of Monroe SensaTracks on my '86 coupe. The suspension was mostly stock, other than the aftermarket rear sway bar and urethane endlink/pillowblock bushings. The ride, as mentioned above, was comfortable on smooth roads, but tightened up during hard maneuvers. The shocks/struts were great for 3-4 years, until they started to soften up too much for my tastes.
With stiffer springs, the softening-up of the shocks/struts may be more noticeable, as the stiffer springs will make the car more "bouncy" as the shocks/struts soften over time. Personally, I'd buy firmer shock/struts (KYB?) to match the stiffer springs. Or you could just buy a new set of SensaTracks every 3-4 years.
