David, the shifting of the sub-frame to adjust alignment is specifically allowed in the factory shop manual. Ref. p. 300-301 and attached screenshot. Note 5 specifically authorizes the movement of the subframe to adjust camber.
View attachment 174442 What isn't allowed is the use of any means to install, locate, or adjust any suspension component that is not an OEM means, method or material. This is explicitly not allowed by Rule 13.1.
13.1 AUTHORIZED MODIFICATIONS
If a modification is not specifically authorized in this or previous Sections of these Rules, it is not allowed.
Your analysis and logic is completely accurate and I agree with -up to a point. A deadset kit or any of it's components that are not a direct replacement only for OEM parts (and serve no additional purpose or function) are explicitly not allowed.
If one chooses to participate in any activity, you are tacitly acknowledging that you willingly accept the rules and regulations that apply to that activity. While these rules can be oftentimes be reasonably argued against, sometimes successfully, for the most part they will remain as written and are interpreted by those assigned to that task by the activity. These rules and regulations are in place because experience has determined that their existence is critical for the activity to function as intended. Are there often loopholes that a clever participant can exploit to their advantage (and the disadvantage of others)? Oftentimes, yes. And if the perceived loophole is determined to actually be a violation of those rules by those with that responsibility, your freely chosen choice to participate also acknowledges your acceptance of the consequences for violating those rules. The choice to follow only part of the rules and ignore the rest has consequences.
