Z1 Motorsports Aluminum Undertrays
 

It appears Z1 has released its own line of aluminum undertrays:

The biggest difference between this and the next most common option (Zspeed) is that there is a larger service panel that drops down.

Anyone tried this yet, or spot any big differences/advantages/disdvantages?

the only other option is made by TBW, and i rarely see that even mentioned

Prices are very comparable

NOTE:
I do not work for Z1
I am not advertising
I am not starting a group buy
I am not buying one, as i already have a Zspeed one sitting at home
This is solely to start discussion on the merits of this product in the community

They don’t have an option for 14 Nismo so I will not be able to buy one... ZSpeed cost around $350 I wish Z1 will get one out in a normal price

I've got the ZSpeed one and had no troubles using the small opening for oil changes. However, I always prefer to remove the entire undershroud. If I'm going to be under the car, I like to check for leaks and other possible issues that might not be visible with the undershroud installed.

Looks good. Mine is being partially held in place with zip ties. I think ill give the Z1 option a shot.

I heard that they are currently working on finalizing the design for the V1 Nismo's, so that should be coming out soon. No idea on pricing for the V1 Nismo undertray as of yet.

Yes, on Instagram they said they are working on v1 nismo

It's a great looking piece. I'd definitely give it a try when I upgrade mine.

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...

Bolt the two pieces together.

I've had a TBW one on my G37 for about 4 years. It's an early design, without the center riv-nuts (it uses the cheap push pin style fastener) and it's just started to rattle. Mostly because my bumper doesn't really line up any more. I'm also not really a fan of the step from the bumper to the subframe.

If your car is an older car or has a bumper that is slightly misaligned, I might suggest the Z-Speed one that is a single piece. Mostly for the rigidity, but also for the alignment.
