Ballast box designs

[Coleydog]

Thanks, good info so far, never had to worry about adding or subtracting weight before in a race car. How is the box attached,to floor, frame, high, low? Figuring out where I want the bars in the trunk area now so if it is attached I can do it now instead of later

You only need a weight box if you are going to run loose ballast like shot bags. I see some who have hard weights mounted with a large stud and nut to the frame rail. You are only allowed 100 lbs. of removable ballast

100 lbs "removable"... So in theory if the car finished up light I could weld in say a 200 pound steel plate to get close then fine tune with lead, that sound right? I like the idea of bolting in hard weights and not a box. Learning

The "trick" is to build your combo as light as you can and then add weight in strategic places. If you place thick steel flat bar plates to a frame structure with two 1/2" bolts and tack weld the end of the nut, then this is not considered removable ballast. Add a weight box to fine adjust for different scales and your set.
