Since we need a few snow tracks, I would suggest the Spa-Franchorchamps but the covered with snow. For PD should this be easy since we already have the circuit, they must only replace the asphalt by snow. And voila our snow track is available for the TRAX cars. Here is a picture from from Spa in the winter, the Eau Rouge is "immer geradeaus!". I have also already made a suggestion for this TRAX Car. And for the option TRAX WHEELS.
