I agree it is a little off the wall, but it's still an original idea by Nobushige Kumamkubo and I think that it is a valid one, but I must say that I'd rather see him piloting his insane Silvia S15 T67-25G Spec.
The 180SX Truck Conv. still burned it up at Irwindale though....
Yeah...The pickup mod is a pretty popular mod now adays among drifters...the "Sil-truck" or "Sky-truck"
People have made these trucks out of S13's S14's and R32 and R33 Skylines....they're pretty cool looking, i'm sure it throws off the weight distribution...but that's easily corrected.
