You already have 448/504 springs with your S-tune setup. Granted the setup is progressive, at least the front springs won't have as much rate spread between initial and final rates as the rears do.

Simply put, you cannot find springs that will out do the S-tune springs, they do not exist. Nismo T2 springs do have higher spring rates (625/725) and a greater drop (1" vs .8"), but I do not recommend them even with your Nismo S-tune shocks.

You could install a set of TomMotorsport sleave coilovers and gain a linear spring setup, but peak spring rates would not change in the front, though they would drop in the rear since the setup now being sold has 450/350 spring rates.

If your not happy with the S-tune setup, pull it from the car and sell it. The setup is very well liked and sell's quickly when the price is right. For what your after you will best be served by a coilover setup vs installing springs that will not deliver what your after.
