Just asking for some springs... Options

[Buffalo]

I have 98' beams convertible with 18" wheels with stock suspension. They guy i bought the car from also gave me a set of lowering springs that he had for it and he said he took them off because the car was too low for him (and his wife keep hiting the front lip on the sidewalks all the time ).
They are red and the part #'s are FKS223VA for the fronts and FKS223HA for the rears (or maybe the opposite), they also have "Made In Germany" printed on.

I did a search on the part # and nothing came out. After searching A LOT through the aftermarket parts companys websites i found that the FK Automotive springs part # starts with FKS but still i didn't find anything on my part #. Maybe they are discontinued.

Anypody have any info on them? How stiff they are and how much lower the car will be with them?
Also what is a good set of shocks to install with them?

I still own my 94' Prelude vtec with D2 racing coilover kit on and verry stiff settings so i'm used to hard rides but for the celica, being my DD, i don't want anything near that stiffness.
