How to get into watching.

There might already be a post on this topic but I have been wanting to get into watching racing for awhile and it is extremely complicated to find out where and what to watch. I am really only interested in the GT3 class(I think). I like watching actual manufactured cars racing. Im assuming the best one to watch is the WEC LMGT3 racing series but I can't even find where to watch that on the WEC website. Any help on this topic is appreciated.
