OK I have a question for y'all. I have installed a VaraRam air intake and a FAST intake manifold only on my C-5 (2001) MY rocket, since doing so I have noticed when I accelerate from 0 to 60 and beyond and at my shifting point at around 6000 rpm I get a twist and a wobble going from 1st to 2nd, and from 2nd to 3rd I don't much look at the speed I am going. Now, the car has I think the F1 suspension it is called, and it is really a beautiful riding car at any speed. I have ordered the Z06 Sway Bars, and the insulated 1/4" tunnel brace. Should I change the shocks also?:confused Scott
