'92 Roadmaster Sedan lift
 

Hello all! First post here; I've had my '92 Roadmaster sedan for just about two years and I've finally decided to get to work on it. I would like to lift the car four inches (not for big, flashy rims I just like the way it would look) but I do not know how I would go about doing this... Would I just look for longer coil springs? Any advice is greatly appreciated!

Bad idea for many reasons--Front suspension geometry, drive shaft angle, worse handling to name a few problems.

Bocoogto gave some good advice. You might want to give it some serious thought.
There isn't a car made today that can deliver a ride like yours can, not even the new Buicks !
