Hey Mr Speedy, i really like your idea of a mini 8 rally car, so i copied your idea.
But instead of making new bodyposts holders, i've drilled 2 holes in my rear T-bone bumper and shortened the front T-bone bumper and drilled also 2 holes in it to mount the bodyposts.
I really like the way the t-bone rear bumper looks like a kind of diffuser ;-)
