Yeah that's me, I read various Z car sites but only post on a couple! I would avoid zcar to be honest, most new people seem to get mauled for no good reason over there
I haven't sorted my suspension out yet, I'm planning on getting the rest of the car finished first so I know what I have to work with weight wise. Thinking of making up my own adjustable setup with the Rally Design stuff, effectively the same as the Ground Control setup but a fraction of the cost.
