but maybe fat squashy tyres and extra weight might acheive the same much more simply.Or adding many powerful permanent magnet fixed to the vehicle but a little above the steel floor would acheive the same equivalent of weight without adding mass.............. alternate N and S would be a good idea.

We have a 15lb weight limit so it's best not to add anymore weight than needed, fixed magnets are a good idea, but I've seen other teams bend axles because so much force.
But thanks for the thought!
