i have agxs. adjustable and come with a warrantee. the warantee is void if the drop is more than 1.5" but since you're using prokits, you don't have to worry about that. it's 4-way adjustable. i have them set at 2/2. 1/1 is almost like stock. 3s or 4s, the car gets a bit bouncy. i'm not sure if koni reds are cheaper than agxs. koni reds are not adjustable so you're pretty much stuck with the ride that you get. i don't know how they ride though. probably a bit stiffer than stock. good luck.
