You might find some impreza coilovers fit the front end.
Rear end the miata/MX5 rear coilovers should work. Or a set from a Gen3 Legacy. Both of these are coil over shock, not a strut like the front end. Both will probably need some mods to fit. I’ve never done it, just remember reading about it some where.
Checkout what Nico did with his builds. I’m pretty sure he’s the fella that built up an RX sedan and an L series wagon to be absolute on road weapons, no expense spared! There might be some ideas in there for what you’re after. Yeah it’s him!
Have fun reading and looking at pics! The early ones have a few dropped unfortunately but many of them are still there
Cheers
