I've heard good things about the inserts, and they're on the cheap. But Hasport is badass. I have their mounts all around and they look good, feel good, and are warrantied for life. No questions asked. Example: I bought my car with them pre installed, I had them on my gs-r so I knew what they were, blah blah. Well because of the P.O. the driver side mount is shreaded and the trans mount is getting iffy, so I shoot hasport an email asking about replacments. They said just mail them to hasport and they'll replace them and mail them back.
Long story short. Hasport is boss. I get 15$ engine mounts for life. doesn't matter how you fuck them up.
