So tomorrow I am going to be lowering my Tahoe 2"ft -3" rear, It seems that the black lower valance below the painted front bumper is pretty low already, It seems that after I lower it, it will be pretty close to the curb stops and parking curbs. What is everyone doing about these, trimming them or taking them off completely?? I am not worried about it, but my wife drives it all the time and I am afraid she is going to forget and plow it into a parking stop. LOL. Also if i were to take it off is that going to affect any cooling issues or something weird???? OR is the whole thing not a big deal at all since it is only being lowerd 2" in front?? Thanks.
