Looks to me as tho the pitch rotation is good. Once the ft wheels are off the track, wt transfer is as good as it's going to get.
You can look at the location of the tire wrinkle, and gather some good chassis setting info. [I've got some drawings that I can scan and post, later]
Videos are a good way to ID chassis issues. A direct side, rear, front, footage would help.
AIRC, loose items such as shot bags have to be in a sealed box. There are also limits as to how high the wt can be, vs top of the tires...
Here tis:
4.2 BALLAST
As permitted in Class Requirements. Any material used for the purpose of adding to a car's total weight must be permanently attached to the car's structure and must not extend behind or in front of the car's body or above the rear tires. No liquid or loose ballast permitted (i.e.: water, sandbags, rocks, shot bags, metal weights, etc.). Weight boxes (2 maximum) made of 1/8-inch (3.2 mm) material (see illustration - drawing 9) may be constructed to hold small items such as shot bags, lead bars, etc., as long as box and contents do not weigh more than 100 pounds (45.36 kg) or as outlined in Class Requirements. The box must be securely fastened to the car's frame or crossmember with at least two 1/2-inch (12.7 mm) diameter steel bolts. Any liquid other than engine fuel being used, located behind the front firewall, (on a front engine car) is considered ballast, and is prohibited. To permit "making a class" due to the difference in scale calibration, a maximum removable weight of 100 pounds (45.4 kg) (or as outlined in Class Requirement) is permitted. Removable weight must be securely mounted to the frame or frame structure by a minimum of two 1/2-inch (12.7 mm) diameter steel bolts per 100 pounds (45.4 kg) , or one 3/8-inch (9.53 mm) bolt per 5 pounds (2.3 kg). Hose clamps, wire, strapping, tape, tie wraps etc. for securing weight or ballast prohibited. See illustration for attachment method. Permitted forms of ballast are: 1) Heavier gauge steel floors such as 16 or 18-gauge (1.30 or 1.00 mm) (heavier gauge and/or plate steel prohibited); 2) Frame reinforcing crossmembers; or 3) The addition of protective equipment such as roll bars, flywheel shield, etc. If additional ballast is needed, and is permitted according to class requirements, it must be permanently attached to frame, bolted with two 1/2-inch (12.7 mm) diameter bolts per 100 pounds (45.4 kg), with nuts welded to bolts. Maximum amount of removable and/or permanent ballast, regardless of class, is 500 pounds (227 kg).
