Touring suspension suggestions

[skateparks]

The touring is getting new brakes and suspension. So far the SLS in the rear looks perfect so I would like to retain that. I know the age old debate of Koni, etc but what would work best in the front? How do I set the stock SLS to accept the lower springs without removing it entirely?

The car needs to ride well, not too harsh, but be substantially lower than stock. This is NOT a track car but will be a 300hp grocery-getter, semi daily car.

Thanks guys...
