Guys, the rear steering is not what you all think, it's only turns 2.8 degrees max! barely visible.
Here's a video how it work and with the wheels on you can hardly tell so not worth replicating on the Lego.
I will get one for sure. I just have to come up with cash somehow and later explain to my wife why there is expensive toy on the shelf. Kudos to Lego for making this GT3 RS my current fav Porsche.
The only thing is I probably will need to figure out a way to cover up the big gap under the headlights a bit.
