[danny the elfman]

hey guys, im just pondering where i should weight my mad monkey for racing on carpet. I have lead so thats what im weighting it with. The picture shows where i have weight in the car. Blue is where i have lead, red is where i have no weight but have space to put it. I didnt want to put it on the edges of the battery tray because im trying to stop body roll abit more.Thanks for reading
