Well there won't be a class system or any pile of rubbish like that. We (NDR) will judge ANY driver with prior IGTC or MoE experience on aspects such as result, behaviour, pace versus team mates, success.
So drivers like Rik De Jong (Sorry to single you out alot Rik :razz
who have driven at a good pace and has had a succession of very good drives would obviously not be permitted to race in the GTAL.
But say you Yann. Your race in the one IGTC round did not yield a good result, and we wern't really on the pace. Thus, you would probably be permitted (after NDR discuss it) to race in the GTAL.
I hope this clears it up for you mate
