Question

My project has a Mustang II front suspension. Currently, the spring ratings are 500 pounds. If I were to go with a 700 pound rating, how much do you think that would raise my suspension?

Can't tell you how much it will raise the front end but the rule of thumb is to have the lower A arms level with the ground. If the A arms are level now and you need more ground clearance the only way to go is larger diameter tires to keep the front end travel as designed. Get in touch with Detroit Eaton spring, they should be able to answer your question.

The result will be dependent on a number of factors...the lower A-arm lever ratio( inner pivot to spring cup vs spring cup to ball joint, and overall arm length), the free length of each spring, and the weight on the front suspension to name the three I can immediately think of.

While increasing your spring rate would raise the front , it would probably adversely affect your fine quality , look into spring spacers for a small rise or different ( taller) springs ....
