I removed the undertray that was fitted to my car afew years ago and got it repainted satin black. Were steel undertrays fitted origanally to 2wd Sapphires? When I removed mine it looked like it had been on since factory. Just ive never heard of them being fitted to other cars. Here is a pic to see what its like.

I will be fitting it to the car anyway as it makes it looks alot better.
