Hey Ive just fitted my new PWR stepped intercooler on my FG, Bumper in back on fine looks sweet however the black undertray in having difficulty getting it right. seems to be suffereing from a see-saw like force which I can only put down to the intercooler affecting it, If I fix the undertray at the front of the bumper the back wont pull up and visa versa. question is can I live without this under tray or is it neccessary to prevent road grime and dirt and sh*t being thrown up on moving parts like the steering rack or something..... intercooler is fresh out the box and polished and shmick under tray is an asshole can I take it off?
