Using this mount kit: First, make sure to confirm that this kit fits your 2002 - 2005 Honda Civic Type - R or 2002 - 2006 Acura RSX with K - Series motors and manual transmission. It's highly recommended that you have a mechanic or automotive specialist install the mounts. Don't try to install it on your own if you're not experienced. Before bolting the mounts in place, double - check that they match your vehicle. Once installed, the mounts are non - returnable if they show bolt impressions. Regarding vibration, the mounts are made to absorb engine vibration, but you might still feel a bit depending on your engine's series and HP. This is normal. For maintenance, there's not much you need to do. The powder - coated finish helps protect the mounts, but you can clean them with a mild soap and water from time to time to keep them in good condition. Remember, these mounts are built for performance driving, so enjoy the reduced wheel hop and increased driving response they provide.
