KSport springs too soft, need stiffer

[The Spectacle]

I have Ksport coilovers on my car right now and the spring rates are way too soft for my drop and as such I rub all over the place. Off the shelf spring rates are:(in kg/lbs)

Front: 4/224
Rear: 2.2/123

Ksport rep on the phone said he can sell me front springs at 6 or 7 kg but is unsure of the rear new springs are $40 a piece. I'm mostly concerned about the front. Anyone know where I can get stiffer front and/or rear springs from? Loren I remember you swapped your rears out but I don't remember you saying from where.

Here's a reference shot of my car



Almost flush with the top of the tire in the front and a one finger gap in the rear. Please don't suggest raising the car, because I'm not.
