1966 Barracuda FormulaS 6 Leaf spring ride height

no i don't want them higher. i like it how it stand now.
i have no comparison how it will ride with new springs. i drove the springs 6500miles. can not say that there are crap..but may it will be a lot better with new ones. thats the reason why i am asking about your rides and experience on them. i made the most on the car self. but here i have no experience. i made a lot updates on suspension and now i am on the rear spring.
