Fantastic stuff!! I love racing this class of car & always get a bit miffed when S397 'break' these great templates, so I really appreciate the update.
After you select your LMP proceed to your Opponent filters and make sure there is only the "LMP1_Pack" or "LMP2_Pack" Opponent filter selected which will then provide you this class!
Note: Added a "LMP1 Pack" Opponent filter in this version 2.05
