The Sports Car Club is talking about making some changes to T5 & T6: http://www.sccbc.net/forum/YaBB.pl?num=1425413824/8 I also hear that since they are going to remove the dirt track they will be removing the inside wall between T6 and T7.
There may be changes to other than T5 & T6 if you continue to follow that thread: Real shitters!!!! :wave::wave:
