Because my civic went from d-series to b-series it was important that I got the appropriate engine mounts for my car so I would avoid my engine/transmission possibly falling out the car. It also gives the car an aggressive feel. So I went with Drop Engineering engine mounts from Teknotik.com for my b16b.Many people that decide to get after market mounts usually only switch the drivers side mount because that's the one that usually breaks first but what people don't know is that you need all three for proper stability of your engine/transmission. Don't be cheap when it comes to doing things properly with your car.
