The picture does look like it's in the boot, but I'm not really sure where the photographers were standing.
As far as tinkering, the motor has heads, cam, intake, headers, tune and a few other minor tweaks. Suspension is springs, shocks and some minor geometry changes. And then wheels and tires are 255/60R17 Eagle F1 Asymmetric 4x4s on 17x8s. Wheels are +10 offset with 3/4" spacers (stock offset is +13).
