Been thinking about those Premium kits and there is one change that I actually would like to see: full widebody kits. I doubt it would be €50k, but I always preferred full length widebodies over cars that have just wider fenders.
Unfortunately, most GT rulesets have only allowed for the latter for the last few decades, so I've got to use an older example:
Kremer Porsche 935K4 (Euro-Version, only wide fenders):

Kremer Porsche 935 (IMSA-version, full length widebody):

I still don't think that it makes economic sense, but from an aesthetic point of view, I'd actually like to see something like this on today's GT3s.
