Hi mate, You should have let me know you wanted some lowering springs for your E30, I sold them last night, you contacted me on the other zone. You dont want to go 60mm lower anyway, you'll never get your wheels to stop rubbing the arches on the rear, the front wheels will bend the arches on full lock and you'll smash your sump and exhaust on every bump on the road.
Your car look right as it is mate.
