Unknowns
- 1976 BMW #1 BMW 3.0 CSL (reward)
– The 3.0 CSL was raced in Group 2, Group 4 and Group 5, it can be put in any of these depending on performance - 1975 BMW #25 BMW Motorsport 3.0 CSL (showroom)
– See above
These are the classes the cars are homologated to, so this would be the ideal split for just focusing on competing against the cars they would at the time.
But this of course leaves the classes empty, so some could/should get combined according to philosophy and performance.
Some ideas for grouping:
- IMSA GTO + IMSA GTP + Trans Am
→ GTO sportscars - Group 5 + Super Silhouettes + IMSA GTX + Group B
→ GTX sportscars - Group 4 + both BMW 3.0 CSL from Unknown
→ GT sportscars
EDIT:
Updated after update 19.
The 924 GTP was featured in races in the IMSA GTO class, that’s why GTP can get merged with GTO. The 961 Gr.B raced in the GTX class at Le Mans, that’s why it can get added to the GTX group.
See this topic for an updated list whenever cars get added.
