I have a 05 st with the stock springs, and svt dampers. Can a set of Konis (non adjustable yellows) benefit me more on stock spring setup (koni and stock spring) than paying for a set of svt springs (svt spring and svt damper). I do not want to lower the car, as roads are bad around here, have alot dips and driveways are very steep. I just want some improved handling on the days I choose to drive hard. From your autocross opinions, what route would you go, springs or konis?
