Using this mount kit is a great way to upgrade your 2005 - 2008 Honda Fit/Jazz. First, before you start the installation, make sure the kit is a perfect fit for your vehicle. You'll need to have a mechanic or an automotive specialist handle the installation. Once installed, you'll notice improved driving performance, like reduced wheel hop and better response. As for maintenance, there's not much you need to do. But keep an eye on the mounts for any signs of wear or damage. Remember, once the mounts are bolted down and you can see the bolt impressions, you can't return or swap them. Also, don't be too surprised if you feel a little engine vibration - it's normal and depends on your engine's series and horsepower.
