The 997 GT3 RS 4.0l is not as special as the 991 GT3 RS? Did I get that right?

The other way around...I think.

this is not true but it does not matter. the 997 GT3 RS 4.0 is very different from the 997 GT3 RS 3.8. Engine, aerodynamics, design, suspension, weight, ... Unlike the RS 991, you can put slicks, making it potentially as fast as the 991 RS. For driving the two, I think the 997 RS 4.0 was an incredible feeling compared to the 991 GT3 RS

And I'm not talking about 3-4000 copies of the RS 991 to be produced.

As for R, we'll see;)
