I'd like some info one the red and black springs. I'm running 27x10x12 Dirt Devil XT's and haven't noticed much if any power lose but more power is always good. I like the idea of having both of the springs, but when in technical terrain i don't need the hassle of nearly being flipped over because of red spring. If the red and black spring are used together will this happen more than if just the red spring is used? Also i've heard that the black spring helps with engine breaking, is this true? thanks.
