I have been making more parts on the F1-02 breakable, but in order to have both damage and aerodynamics working properly the blender objects have to be at the origin and then moved using the centre parameter of the box section eg.
[suspension-front-left]
texture = body00.png, body-misc1.png
mesh = suspension_front_left.joe
position = 0, 0, 0
mass = 2.5
[suspension-front-left.box]
center = -0.47, 1.57, -0.35
size = 0.65, 0.76, 0.43
as changing the position parameter messes up damage, and moving the objects in blender breaks the aerodynamics. However this means the car preview widget displays the car wrong:

I've uploaded the changes I've made to the car so far:

On the up side, your latest commit fixed an issue I was having with adding more than 3 breakable parts.
