Yes, coilover springs (front & rear) are manually adjustable - usually up to 3.5" - and used mostly for racing applications but there is nothing to prevent anyone from using them on a street car and some people do. You'll get a harsher ride from the increased stiffness of these (mostly) race springs with higher rates. Special struts and shocks must be used with coilovers and installation can be tricky.

Not so expensive as to make them unreasonable and you do get the adjustability factor but frankly, these suspensions aren't a priority for most street-driven Mustangs. Coilover springs are more often found on import cars.
