Talking front strut tops:
S/V40 are the same as Evo4~6, CE~CH Lancer.
The mounting studs on Evo 10 tops are closer together (on a smaller PCD).
Evo1~3 tops are two bolt.
I can’t remember what Evo 7~9 tops are like, but I think they’re also suitable.
——
Rear tops are all the same, from CA Lancer to Evo10, and including S/V40.
——
CE Lancer have smaller diameter front springs than S/V40, and later Evo. S/V40 and later Evo have the same coil diameter but can’t remember what any of the other cars had.
——
My inclination would be to try standard T4 springs on the Bilsteins you already have.
My V40 was the most comfortable on similar Bilstein shocks to your car, and whatever springs it ended up with (I think Eibachs). They were much better than the B4s it came with, and much better than the various cars I have owned with standard shocks.
