@reconn08 You are correct. To clear things up, I did not remove it to go faster. I wasn't hitting speeds where it mattered. I took it off to shave weight.
nice pickup, i have datsun 720 model 1980 with nissan z 1600 engine. you open the back door. the air cut speed. what about on max speed? is it realy cuts?
@helenaki8 the aero-dynamic is not better if u remove back door so u cant go faster as the fuel economy wont be better.. It is said and tested and proved. Google it somehow.
