For years it was said the GT3 rules are going to have massive changes from 2016 on, but so far this isn't happening.
And "global BOP" isn't right either, since the German ADAC is BOP'ing the GT3 cars on their own for all VLN races. But for the last two to three years it actually worked.
But yeah, would be cool if GT3 cars could go back to their original speed from late 2005/2006. Racing would be as close, tight and interesting but it would be much, much safer on the Ring - and other tracks presumably aswell.
You know what's funny though? The GTR did get an Evo package for 2015, apparently nothing has changed on the front compared to it lifting its nose up last year...
