well the top touring car series atm is german dtm. the cars are technically silhouette cars but they are included in the touring car specification as is v8sc which is also silhouette.Whatever happens I just hope that the top TC series has a few RWD cars, these FWD cars are the work of the devil...
btcc is the next most popular touring car series and they have a rwd car.
wtcc has been down on viewership for the past few years so isnt the top tc class.
