Adding weight to a 4 link G body?

[Jeff Stout]

Thanks Jim. I had someone private message me the same location but try to go higher such as rear roll cage down bars. Now to come up with 150lb and secure as I only have 60lb of lead.

If you mount a weight box (Moroso - Competition eng) to the hold downs (or a flat steel plate) you can add pieces of steel, wrenches, etc to the box - in addition to the lead.

Keep weight below the top of the wheelwells (per the rules) Weight ahead of the rear axle will add some static weight to the front end , but could add some dynamic weight during the launch .

Thanks for reminding me about height at wheel wells per rules.

Can the weight box be secured by a thick "sandwich" plate under the car or does it have to be welded to a structural member of the car ????

Mine is bolted thru the pickup bed - Been thru tech at Nationals and Divisionals for years - don't know if it is in the rule book - 6 bolts on the Moroso box.

Unless you are going through a frame crossmember, that does not appear to be legal.

Per Section 11a, page 6 of the 2016 Super Stock Rules:
BALLAST.
Weight box permitted. Only 100 pounds removable ballast permitted, including box (two-box maximum with 50 pounds each). Must be attached to frame or crossmember with minimum of two 1/2-inch bolts. May not be attached to roll bar or cage. Additional ballast must be permanently attached to frame or crossmember; i.e., bolted with at least two 1/2-inch bolts per 100 pounds, with nut welded to bolt. See WEIGHT. See General Regulations 4:2.

I have seen cars and talked with racers who have been through tech at numerous National and Divisional events with weight boxes NOT attached to a frame member. They all told me it was never a problem. So I mounted mine in the corner of the trunk floor with a large plate on the bottom and six bolts holding it in place. Second or third divisional I attended I was told to read the rule book and change it before the next race.

I'm guilty of not having the latest rule book and now knowing that you can't bolt weight to roll bar. I know of one car that has it that way. Mmmmm

The rules are to keep you safe: strong and durable is good, flimsy not so much.

Weld in some U channel between and to the frame rails to make a cross member, then bolt your weight to the reinforced area.

I always try to ask myself this question: what happens if.........., and will it be strong enough?

You can read the rule book on line.
