I am using associated oil too. Kyosho lt blue springs in the front and orange in the back. In my opinion..don't use csi bladders or boots on this car. I think they are junk. Had my boots a week and they ripped and the black bladders make the car bounce everywhere. I spoke to csi about it but they just keep telling me to buy more of their products even though they haven't done any testing on the eb48. They can make guesses with their money but not mine.
