OK, I looked up the Mazdaspeed touring kit catalog from Dec '97, and it lists the coilovers under the unified part number 9EP 30 001. So maybe that's the one! (BTW all Mazdaspeed coilovers from 97 and on all look alike- blue body w/ gold springs and single allen bolt spring seat. The earlier coilovers had the 2 piece jam nut style seats.)
Specs for the 9EP 30 001:
front: rate=2.91kg/mm & 4.0kg/mm; damping force= 270-330kgf rebound, 40-60kgf compress
rear: rate=2.09kg/mm & 2.60kg/mm; damping force= 250-320kgf rebound, 40-60kgf compress
The adj range is listed as +10mm -> -45mm. No physical dimensions are given. Note that the damping force numbers and the adj range numbers are identical with the 2000 spec. Only the spring rates are slightly different.
