If it's accurate lengthwise, this may end up being the longest GT3 on the grid (so far).
The M6 was the longest GT3 yet, on par with the Slot It Maserati Gran Turismo and Nissan GT-R GT3's.
Not counting the M8 which was a GTE - and the laughing stock for some, because of its' huge dimensions compared to others - the M4 GT3 surpasses all of them on size alone (being well over 5m in 1:1 scale). It's not a small car, mind...
Better get used to bigger and bigger cars on track, larger ground clearances and bigger wheel arches to boot as GT3's just aren't the same low-rider styled GT's with wheels tucked up in high in the arches and splitters scraping the track, as GT1's & GT2's used to have up to some 10 years ago.
Just look at 1/32 (or 1/24) Carrera slot cars, while lots of us slot additcts look at their substantial arches and wheels and think they're really oversized, they actually aren't. They are quite accurate...
