That's why I'm not such a huge fan of those Land Rover roof-racks with
spare wheels and all kinds of heavy stuff on...

What I meant about the center of gravity is that if you "guess" it wrong,
the sim will behave very strange! And so far I've never seen authentic
data on this - could you tell me yours? Preferably in height from the
bottom of the floor or something, i.e. relative to the chassis, not the
ground, as I don't know how high your car is.

About the spring rates, I've seen a data sheet once, for Mercedes
Geländewagen. I'll try to dig it up.

About the realistic car sims - if it's not an original idea, how come
nobody's done it? (Okay, Racer is good - but all those arcade racing
games with FAKE!! physics annoy me to death)
