Where are you jacking up your X in the front?
When I first went to jack the car under the front motor mount I noticed that the front undertray was very hollow in that spot. I was forced to jack it from the sides first and removed the tray, then jacked the front end under the front motor mount. I plan on making an access panel of some sort so that I don't have to take the undertray off every time. For now I left it off since I'm putting on a FMIC and exhaust over the next week but it's a ton easier jack the front under the motor mount with a rubber pad on the jack.
