Pressure Relief Vent on NISMO
on Nismo's back bumper, there are 2 slits present, as they call "Pressure Relief Vent" like the ones on Porsche GT3 and 370Z Amuse bumpers.
As some sources say, Nismo Aero Kit including the entire back bumper is FULLY Functional without gimmickry, but some has suggested that those slits(vents) are only for looks.
Could anyone please explain?
Thanks in advance!
