engine – optional, usually the official name without "engine", case-insensitive
tech – optional, string containing the first letters of all tech cards the vehicle needs (eimacrp), in any order, case-insensitive e – Early Tech i – Initial Tech m – Mid-Tech a – Advanced Tech c – Common Tech r – Rare Tech p – Pro Tech Example: tech = iem would display guarantees for Initial, Early and Mid-Tech.
class – optional, string containing the letters of all classes (dcbas), in any order, case-insensitive d – Class D c – Class C b – Class B a – Class A s – Class S Example: class = abc would display guarantees for Class B, C and A.
strict – optional, 1/0 or yes/no
0 or omitted – also displays the current distribution of 1 Part Boxes (for example 1 Part - B Box) to provide additional information for players on R&D and other event pages.
1 – displays only guarantees in the strict sense (for example on Pro Kit Box statistics comparison where a list of all 1 Part Boxes would not make sense because the values are already included in the tables).
As there aren't many guarantees concerning single Pro Kit cards, it is possible that the template dispays nothing. However, if a new rule is added later, it will appear on all pages the tempate is used on without further maintenance.
