Well, what sort of price range are you considering?

There are a few shocks available for the car over not too wide of a price range.

Koni Sport (a.k.a. Yellow) - adjustable damping, limited height adjustment (the spring perch has 3 mounting heights), generally regarded as the best, run about $600 for the set but sometimes deals can be found
Tokico Illumina - adjustable damping, pretty nice but not quite as good as the Konis, go for about $475 for the set
Tokico HP - non-adjustable, supposedly a "performance" shock but not much of a difference over stock
KYB GR2 - pretty much the same deal as the HP
