Oh, they will definitely make a difference. I am just saying that you will come out wanting more. Happened to me with my suspension setup. Switched to KYB excel-g and lowered springs, RSB + strut brace and was pretty happy. Put in some poly bushes and was pretty happy. Took it up for a few hard mountain runs and became very unhappy. At least I know I have some Koni Yellows which will set me straight.
