Tokico HP (blue) are a mild upgrade over stock. Not very stiff at all. They're not a great match for GCs because the stiff spring rates essentially overpower the shocks.
You've got a '90 car, it probably has the original shocks which are like 12 years old. Get rid of them quickly. Try and swing some Tokico Illumina shocks over the KYB AGX, they're a bit nicer. Those and some not-too-aggressive springs will give you a nice ride.
