I am also testing a new chassis from BCE which is lighter and thinner than both chassis offered by hotbodies............the chassis just keeps getting faster every time out, the first time I ran the car I left my base setup just to see what the car would do, second time out I lowered the shock oils front and rear, went to a lighter rear sway, and lowered the diff oils and it was even faster, with the BCE chassis that is thinner and lighter then both the stock and aftermarker chassis it makes a big huge difference in the handling characteristics for the better.....if you have any specific questions you can email me at [email protected] or shoot me a pm.
