Well, I have made a mousetrap car not too long ago so hopefully I can help. However, mine was very different from the rest of the cars, but it went 3m.

My friend's mousetrap car got the first place (almost 100m!) and his lever arm was very long. Also, I think he used a fishing rod string. When the mousetrap car was moving the leverarm went down very slowly, allowing the car to go further. If the leverarm goes down quickly, the car will also stop quickly.

Sorry, that's all I can remember... I just had a quick glance, I didn't look at it too closely.

Well, I don't *think* it really matters, as long as it's stable and not too heavy.
