I do think that the GT3 RS shares its rear wheels and rear hubs with the 918, which is a good thing.
Why? It just means that 918 is undertired (almost 400hp more than RS) - Dodge Viper has wider rear wheels/tires and so do many other cars... RS' performance comes from similar tire setup as 918- if it had the same wheels/tires as base GT3 it wouldn't be much faster than a GT3(certainly not 5 seconds quicker at the ring).
