Product Description

The Z1 Motorsports Aluminum Undershroud for the 2015+ NISMO 370Z was developed to replace your stock plastic or missing undershroud with a rigid aluminum panel, increasing front fascia rigidity, improving air flow, and making oil changes easier!

The stock undershroud on your 370Z was designed primarily to protect sensitive under body components from weather and small road media, unfortunately these plastic panels are not very strong and are susceptible to damage. The Z1 aluminum undershroud provides far more protection than stock by providing more rigidity and durability than soft plastic undershrouds. The boxed and skirted mid-panel further improves fascia rigidity.

The Z1 undershroud does away with the flimsy plastic clips that hold the center section to the crossmember. Instead, we elected to use rivnuts and threaded hardware to better secure your undershroud! The best part, is that you don't need to purchase a rivnut tool to install your undershroud, we've included one with the hardware at no extra cost!

Also available for non-NISMO 370Z models! Find Non-NISMO options HERE!

Removable Service Panel

In order to service your car the undershroud must be removed. If you don't you'll likely find yourself reaching through a small rectangular hole hoping not to cover yourself and your undershroud in a thick film of oil after removing the oil filter and drain plug. This is no easy task. The Z1 Undershroud has a removable service panel, considerably larger than other similar undershrouds providing you with easy access and plenty of room to spare!

The removable service panel features large vented louvers, helping improve air flow on both sides of the panel and evacuating lousy heat.

Now available in two finishes!

  • Aluminum
  • Anodized Black

Features:

  • Large Removable Service Panel
  • No More Messy Oil Changes!
  • Louvered To Extract Heat
  • Includes Hardware
  • Improves Air Flow

Fits:

  • 2015+ Nissan 370Z NISMO
    Including models with '15+ Fascia Conversions!

Fits perfect on my 2016 370z NISMO and looks amazing. Car is lowered and doesn’t scrape on pavement. Makes the bumper feel more sturdy. Way better than the plastic liners that often flapped and caught on every uneven surface. This is a MUST for any Z.

Great product! Keeps the front Nismo bumper stiff. Super light weight and easy to install with one exception: the two bolts on the rear of the middle panel that is attached to a bent over portion is a pain to install with a normal wrench due to limited clearance on both the depth and sideways due to subframe. Using a ratcheting wrench would be highly recommended as there are many, many threads. It would have been an improvement if they were designed to be accessible directly below (the plate not covering them/outward bend instead of inward but that would reduce the coverage by 2 inches maybe this was a compromise) Love that all new hardware were supplied in case of missing hardware from previous shroud damage. Would have also been great if 2 plastic clips were included. Hard to attach one of the screws with floppy trim piece next to the beams that you drill out. The overlapping trim pieces would not align easily with missing clip, just a suggestion.

No more sagging bumper. This undershroud makes the bumper stiff, helps it not bend back when the air hits, and gives it extra support over the plastic undershroud. Easy installation and comes with all the hardware which is nice!!

Works and bolts up perfectly, really strengthens the bumper which is great. Only downside is it sites slightly lower than the oe undershroud. I'm not super low but it scrapes occasionally over bumps

This undershroud is so convenient for oil changes and overall aerodynamics. It doesn’t get in the way of oil changes nor does it make any annoying flutter sounds that the stock splash shield makes when driving. It doesn’t scrape at stock ride height for me either. 100% an upgrade

This Z1 aluminum undershroud was definitely a step up from the factory plastic. I realized it was a 3 piece and the rear panel was a service panel that slides into panel 2 and 2 bolts on the other side. So take out 2 bolts and it slides out, Boom Oil filter. Whoever invented this was a damn genius. 10/10

This aluminum undershroud is much better than the flimsy plastic OEM undershroud for the 370Z! Had to finally replace after it started coming undone and was dragging on the ground. Seems like this will hold up for a while. Installation takes a little time but it's worth it if you need a replacement!

I’ve had this installed on my V2 nismo for 3 years or so now with a perfect fit. Definitely a must have upgrade. Makes servicing the car a piece of cake. I also feel like the underside of the car is far better protected. Aluminum is better any day of the week than plastic.

Seriously fit like a charm. So glad I got this, as it adds so much rigidity, it’s nice knowing your filter and pan are well protected. Beware, as they say in the instructions, leave things somewhat loose when putting together. Shall save you some hassle 👍🏻👍🏻

Awesome under shroud. Keeps my V2 front bumper in place. Came with all the hardware needed, i didn’t have the instructions at first, but that was nothing a call to Z1 wouldn't fix. Also for those having problems with drilling the hole out, its actually fairly simple. The hole gets drilled out to a slightly bigger size, then you put the riv-nuts in. I used a 3/8” impact gun to put mine in because it’s hard to do it by yourself with the way the angle is. Other than that, awesome product. You guys should make a V1 version with the long plastic plate needed too, you would make a killer profit.

I bought the stainless model but they do the same thing . Very easy to install , the rivets are a pain in the bums.. Tip: use a drill on med setting , instead of fighting awkwardly with wrenches underneath your car. Drill is quick and applies enough torque to have riv nuts expand. This shroud will protect all those vulnerable pieces underneath your car, oil changes are a breeze now, your mechanics will love changing your oil.. 2 bolts from 30, lol 😆.. plus it looks good and is much more sturdy than that plastic mess Nissan uses .. should be standard !

5 stars. Very well made product, looks fantastic in the anodized black finish. It is clear to see that some real thought was put into the design and manufacture. Including the rivnut tool proves that Z1 really does care about their customer. Would recommend this to anyone who changes their own oil on their Z!

Really good product if you're wanting to change your plastic undershroud to a metal, more sturdy one. Install is relatively easy with all bolts fitting in wherever they need to. Best feature, in my opinion, is the service panel on the back end of it making reaching your filter and pan easier without the hassle of removing the entire shroud.

The product looks great, is very functional, and far superior to the factory model. However, on my 370z it does not line up properly with 2 of the bolts which are unable to be attached. With all the other bolts it feels secure enough even without those 2. Also the metal is extremely easy to scratch. Simply setting it down wrong will cause very visible damage so I am sure after a few weeks of use the nice finish will be gone.

Amazing quality and fitment! To all those looking to buy this SERIOUSLY MAKE SURE YOU HAVE FULLY RIVETED THOSE EXPANDING RIVETS INTO THE SUBFRAME PROPERLY. Its not a quality issue i'm just saying dont install this in a rush take your time and savor it.
