The International Registry submission form at http://rx8owner.com has been updated to reflect UK model specifications. As for the Vehicle ID number, please let me know if the format works for the UK.

Can you point me in the right direction as to where these UK specs are on this site?
They aren't on the registration form!!!

Let me clarify

At http://rx8owner.com/register.html the menu boxes have been updated beyond the US options. Added the High Power and Standard Power to models. Also Type S and Type E for Japan. Km instead of miles. Also the 5 speed manual in the transmission menu.
