It would be cool but do teams still need Nordschleife specific parts in order to run GT3 cars on the circuit?
This article doesnt provide the answer to that but it offers an insight into just how complicated it is for the 24 Hour race.

My worry would be if teams need to buy specific parts just for the one race or if teams would need to do additional testing. It pushes up costs and in todays world thats not a good thing. Would be a cool race though.
