Michael Melcher:not to argue, but it says that "jacking rails" are not permitted - there is a difference between subframe connectors and jacking rails... besides, the convertibles come with bolt in ones stock... would that count in the update/backdate stuff?
What you've got to look for in the rules is something that says subframe connectors are allowed, and nothing that says they're disallowed. I don't believe you'll find that in the Street Prepared rules (although I've been wrong once before).
BUT, since the convertibles have bolt-in subframe connectors, you are free to use those same pieces in your car as part of Street Prepared's update/backdate rule.
