Recently put on spacers and have had no issues with it. A bit after putting them on I notice a creaking/rubbing noise from the left rear only, I thought maybe it was something to do with the spacer so I took them off but the noise is still there. At first I thought maybe it was seized caliper or parking brake but it doesn’t sound like it. Might be suspension but it happens when driving straight on a flat surface with no bumps. Anyone have any ideas?? It’s a 05 manual coupe btw

Bought a lip off eBay for my 2005 coupe, it fits base model bumpers only and I thought mine was the base model bumper but it didn’t seem to fit when I held it up against the bumper. Mines the 6mt with sport tuned suspension, is there any difference in the bumper between the 6MT sport and base AT? I thought it was just sportier suspension and the rear spoiler. I also thought only 07-08 had the “sport” front bumper trim with the stock lip. Also have some brackets on the lower part of the front bumper from the previous owner, anyone know what that is?
