Most all of the above input is valid.
That said, I have not scene a coil-over modification into the stock suspension geometry. If cost and the requirement or interest to explore a new solution are not a concern,.... go for it.
That said,...that said, cutting a coil and relocating the spring pocket will get you a decent drop, at virtually no cost. And the original spring has already "settled". And yes, remounting the shocks are a given. The ride will be stiffened and drivebility improved 'tho understand that in extreme cases the suspension may bottom out which is the cost of having a car with a more contemporary appearance.
I did all that but eventually ended up with a IFS clip because I can't resist messing with, exploring the options.
Good luck. How 'bout some pics.
