Best way to raise my Duster

Nose seems high and the rear looks low-ish. What are your front and rear tire sizes. Springs are the only way to properly correct the rear ride height. I wouldn't jack the up in the *** to match the front, it will drive like hell. What engine does it have and was the front end rebuilt recently or torsion bars replaced?

The front tires are 215/70 R14s. The rear tires are 225/70R15s.

The engine is a 318. I don't think the front end has ever been rebuilt or has had anything replaced.
