It becomes a pain to remove front spoiler every time an oil change needs to be done. For the +11' year models Nissan changed the design of the front lip to allow for this. The GT-R owner community performed this modification before Nissan :)
Simply drilling 4 holes in the front spoiler allows to access the front 4 screws of middle shield/panel that covers the oil filter and oil drain plug.
Remove the front lower spoiler using the instruction in the oil change blog.
Remove the middle panel.
Place the middle panel into the front panel while the 2 are laying flat on the ground. and make marks of the 4 holes on the front spoiler.
