Hey guys, I'm new to the states so I don't know much about the state laws. Looked up the CA drivers' handbook but couldn't find anything about it either.
How long can I have my dealer plates on?
Planning on leaving it on until Clokwork ships the front license plate bracket to me.

I don't know the answer, but you should be OK with the paper plates as long as you have the temp reg. in the window.

I believe the temporary registration is good for 90 days. You can check at www.dmv.ca.gov.

my friend has had his temporary registration on for two years now on his STI! crazy! i don't know what will happen if he gets pulled over. but 2 years and going.

Temporary registration is good for 90 days like yamashirod said.
