Hi I just got my 2015 civic Si Sedan. I need to install either a hitch or a roof rack for carrying bikes. I've always used a hitch rack on my old Toyota corolla and was going to do that same here. However I read somewhere that some cutting of the heat shield (or something similar) underneath is required to install the hitch. I don't think I trust Uhaul to do that. Does anyone have any experience with either roof rack/hitch installation on the 2015 sedan? Si is definitely different at the back bumper than the normal civic. Thanks.
