The WRC cars will run but will not be eligable for BRC points. Also the cars will run further down the field, like maybe you will have the top BRC runners seeded before the WRC cars. Bit daft as the WRC cars are likely to catch the slower cars on the stages at some point. I hope to go back to the Jim Clark next year to catch the Genie again on those big jumps-he just dosen't lift.
