For the rear wheels, try this.
Build an X pattern out of a couple pieces of flat steel. At the center of the X, attached a 3/4 inch threaded rod, and cover with 3/4 inch ID PVC. Bolt the X pattern to your rear wheels, and then slide some weight lifting weights from Walmart on the rod. Then put the nut on the end.
You need to measure the threaded rod and PVC to just a touch longer then the total distance of the weights. I'll try to grab a picture sometime soon.
Works good. Should add some weight, but you'll need more on the back.
