Japanese tuner RWB (RAUH-Welt Begriff) specializes in giving older generation Porsche 911s wide body kits. These extreme aerodynamic mods are all unique. Nakai-San, the founder of RWB, treats every single Porsche 911 differently and creates a new design every single time. The 911 in this clip comes with wider wheel arches, new front and rear bumpers, wide and lower side skirts and a huge rear wing. RWB's 911 all come with custom alloys and new suspension systems. We're not really sure if Nakai-San upgrades their engine too, but they sure look fast to us.
