1” or 2” lift Espo springs

they were only 5 leaf. bought the car from a friend so i know they were espo 5 leaf (got the receipt with the car). the slightest amount weight in the trunk or back seat and the car would sag.. couldn't figure out why (never really looked at the springs closely) until i pulled the springs because i didn't like how high it was and saw they were only 5 leaf. i have since put a set of stock height eaton 383 dart springs on it..
If i were to get the same +1 but 6 leaf so it wouldnt sag like you were talking about, would it still sit the same as your pic or does the extra leaf make it higher?
