Z1 Motorsports Aluminum Undertrays

Rusty

I have the ZSpeed Nismo V1 since when they first came out. Mine has been bent a couple of times on the track from hitting curbs. I've beaten it flat with no issues. I say this. The Z1 is cheaper. But if you are planning on installing a splitter. Get the ZSpeed. It will give you a flat bottom with no steps.

I honesty wouldn’t purchase the Z1 engine under shroud. I did purchase the Z Speed Performance engine under shroud from Joe only because I was having high engine oil temperature on track days and this under shroud has small openings in the bottom of the under shroud to promote air flow and I can say it did help coming from the Genuine Nissan plastic under tray. I do like the openings though so I can perform my oil changes more efficiently not having to take the whole under tray off every time and it’s simply convenient. I can vouch that the Z Speed Performance aluminum engine under shroud is a very nice aluminum piece for what you are actually paying for as Rusty said before that aluminum prices are expensive. Overall quality and fitment is excellent. Thank you again Joe for doing your best to support the Z community.

I have it on my 17 nismo. It fits perfectly and is made well. I like how it has more access than the zspeed undertray. It is also made with cooling vents built in.

It does look impressive. But I am worried about that tongue and groove design between the access panel and the rest of the shroud. I would be worried about eventual looseness and rattling. Have you noticed any issues?

Their design is the same as TBW's 350Z design. Had two of them for my 350Z for 250K miles. No rattle issues so long as they're fastened tightly. If you have rattle you could line the connecting edges with speaker foam.

Only concern I have with a 2-piece design is that if you make contact with something like a blown out truck tire on the interstate, the impact will bend the plates and they wont align perfectly. Then, much later, when you run over a dead possum, the bent plate will bend more, make contact with the road, grind itself to fiery oblivion, and you'll need to break the radiator core support to remove it when you're on the side of a rural highway in buttfvck Nebraska.

Oddly specific, I know...
