The 40 profile tyre that you are running is a start for stiffening the
ride, but that profile tyre makes it very easy to bend the wheels. The
coil-over system is excellent if you want to very the ride height. The
system comes complete for front and rear. 2Bennett Audimotive can set
you up with the right spring rates and length for a compermizing
ride(90%- street 10%-track) but remember you can't have optimum
handling with a prominent street setup. The ride height can be
adjusted with the spinner nut about 3". I think this would bennifit
your set up needs.

Going with Billsteins and stock '92 spring would be easier and less
expensive, but wouldn't give you a variable ride height. This
adjustibility would come in handing when it starts to snow or you plan
on driving on a track. 
It's easy to adjust. You jack the up car so the suspension is
unloaded, remove the wheel, loosen the locking bolt, turn the spinner
nut with the spinner nut wrench to the height that you want, re
tighten the locking bolt, and adjust the next wheel. 
Why pass up the opertunity to up-grade when you are already going to
have the suspension apart.
Billsteins or Koni's sports are good shocks for spring rate under 600
lbs. . So either would be a good chose for either setup
(coil-over,stock).
