spring rate question?

[Stang8psi]

for the suspension pro's Is a spring rate of 537 front and 269 rear to soft or to hard for a 02 mustang gt. Some help would be great as to I have no clue as far as what spring rates are good vs bad!!!!

To soft to me, 650/300 for a specific spring is about average for a mustang 94-04 that you want to handle good but not be super ruff
