Drop springs is 3-5 ok without c notch?

[C0UCH]

Bit of an old thread, but relevant. I see a lot of talk about not using a 3"+ spring up front, but looking at the Hotchkis site today they have a 4/6 spring drop available. I'm going full Porterbuilt coilover (when I have enough funds) but for now want to throw some lowering springs in until then. Says they include some parts for use with stock arms, but I'm not 100% sold on it if even 3" is giving troubles. Any input on this?
