I am pleased to announce that the FIA has released most homologation papers for public review thanks to the recent popularity of the historic classes and its introduction of the 2017 “Appendix K” regulations.
You can easily find those related to Group B in the HOMOLOGATION LIST of the shrine or in each vehicle’s spec sheet. Simply click on the homologation # to view the PDF file or be redirected to related page in the FIA Historical Database.
This should greatly help those in need of more technical information about the cars!
