Guys I am thinking of putting Pirelli trofeo R spec tyres on my car any thoughts around the rear tyre profile will need to increase from 30 to 35 making them the same as the front but the side walls increase in hardness so not sure what that will do to ride and will it encourage less understeer I am interested in anyone's experience with semi race tyres on roads

Thanks
