Would it be bad in any way to drive around without a rear motor mount?

 

Yes it is bad. Your rear mount is the mount that absorbs all the torque from your motor. If you drive without it your engine will rock like a ****.

You can drive like that but expect to replace some axels.

 

they about summed it up for you

 

I drove my crx around for about a year without a rear engine mount bolt. When I was installing my DA brake booster and master I went to remove the rear mount bolt to raise the engine so the booster can clear the intake manifold and guess what, I forgot to put the bolt on.
