Pagani Zonda (soon to be single make cup) was started on, but put on hold waiting for data.
Audi TT RS VLN is in the hands of Jürgen Wohlfarth for feedback on the handling, waiting for news from him.
GTR2 / GTR1 : dropped an idea somewhere on the forum about merging them and bringing in there the remains of the GTRX class, there's a pro and a con to that. Still think it would be good to have them all in a class with GTE specs.
