Mounting weight in car?

[Jeff Stout]

The way I have read the rules there are 3 forms or types of ways to install weight or ballast.
1- 2 weight boxes that weigh 100lbs each
2- 100 lbs of bolted to frame removable weight
3- Bolting and welding permanent weight
Total of 500 lbs max.
Asking as I need to add like another whole car of weight on Olds wagon. It is way to light for T or U/sa

No. The 2 allowable weight boxes can not weigh more than 100 lbs. each including the contents and only a max of 100 is considered removable. Yes. Up to a max of 100 can be bolted to the frame and this is " removable ". Yes. A total of 500 lbs. is allowed but the holding hardware needs to have a shot of weld to satisfy the permanent requirement. So if you need, say 460 lbs. , then figure a way to put 400 in as permanent and make a box to handle close to 100 and you're all set.

He is what I'm thinking of doing.
200lb bolted and welded
100 lb. Bolted
1 weight box with contents 100lb
Does this work?

The way I understand it is you can have one weight box with a max weight of 100 lbs,or two with a max weight of 50 lbs.each.Or you can have 100 lbs bolt in weight but no weight box.Any other weight that's needed up to 500 lbs,has to be welded.Maybe I've been doing it wrong all these years lol......gsa612

Still not there.
Assuming you need 300# ...100 to make T, 200 and change more to make U.
So you want 100 # total including box. The heaviest spare that fits the car, it's mounting hardware, plus a factory jack. That weight is free. Doesn't count as anything towards the ballast rule.
Now make up the difference with a piece of plate or railroad track, two 1/2" bolts through frame , per 100#.
Now, when you want to go back to T/SA, take the complete weight box out, the spare and jack , plus some gas ,and you're there.
BTW , I had 650 # in my Omega for O/SA, and nobody weighed anything. ;-)

Glad you stated 650 lbs. I thought I was crazy needing 430 total. Small spare and jack is in it already

Question on the 1/2" bolts thru the frame. What about a uni-body car?

Don't put the weight in the middle.

Dave, You can go through the sheet metal sub-frame, with some big flat washers or plate underneath.

That's nothing. My turbo Mustang had that much.
