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.
