My bumper is currently off the car to be painted. Aside from the radiator and other bits being more vulnerable to road debris, is there any harm in driving without the front bumper on the S2000? More specifically, will rain hurt anything that is currently exposed?

 

ur bottom plastic pieces now dont have anything to be attached on so they are weak against the wind resistent which will cause for it to drag on the ground and eat up..... this is from my experience make sure u figure some way to tighten those with wires...

 

That's taken care of with nylon zip ties . Anyone else?

 

Wow, and I though it looked bad when people drove around with unpainted bumpers. This must look completely ghetto going down the street.

If you have a CAI, the air filter will be completely exposed.

You might want to take off the metal clips that the bumper screws into on the undertray. You don't want to loose them.

You might want to come up with a way to sheild the air pump on the left side.
