Rowdy - No.
Basically Chris and I were discussing this yesterday and we have decided that moddified class will be for tyres with a UTQG of below 100.
So that means tyres such as the Federal 595RS (UTQG 180), Falken Azien RT615 (UTQG 200) and Toyo R1A (UTQG 100) will all be eligable for Standard Class.
We will put up a list shortly of all tyres that will fall into moddified class but the Federals will definitely be in standard class.
