Hey guys, I see this thread is pretty old but I have designed an affordable Aluminum undershroud for the 350Z and with a minor change I am going to make will also fit the G35's, I have test fit this on a coupe only, Not sure about the sedans but would imagine they are the same.
If there is enough interest over here I will post them up on the vendors section.
Here are a few pics of it.
I designed a oil change access door in to it also so you can actually get to the filter and drain plug without it running into the shield. Lots of room to get in there now
This also retains factory ground clearance under the car.
Weight is 4.5lbs
PC Matte black Aluminum
Oil access! 2 bolts makes this easy to change your own oil!
