Product Description
Z1's 370Z Strut Tower Brace is designed to reduce chassis flex during cornering, providing sharper turn-in response and making your Z feel more predictable and nimble.
Like your Z's original brace, Z1's brace is triangulated and ties together three points; however, an increased number of structural elements tie together the chassis points more effectively, leading an increased rigidity over the factory brace. In a physical torsional rigidity test, we found this lightweight brace to be 10% stiffer than the much heavier factory 370Z brace. Finite Element Analysis (FEA) strength simulation and real-life physical testing was completed to validate the results and make a direct comparison to the OEM 370Z strut brace.
Our brace is constructed from precision bent 6061 aluminum tubing with a 3mm wall thickness and tig-welded to CNC machined billet end plates. This construction method reduces the overall weight to 5.5 lbs, a 54% savings from the heavy stock brace.
- Rigid Aluminum Construction
- Billet Aluminum End Plates
- 54% Lighter than the factory brace
- 10% Stiffer than the factory brace
- Easy to install
Fits:
This bar will fit with the stock engine cover, however, users will notice that the bar will be off-center with the cutout on the cover.

Everything is great and looks good but wasn’t informed that the middle cover piece won’t fit unless modification is done.

Simple swap and install. A good deal lighter and stiffer, will surely help tighten the car up come next autoX season.

I just installed the brace without a hitch, the instructions were clear and unambiguous. The quality of the materials and construction were quite evident, with good welds all around. All of the bolt holes lined up perfectly with the car parked on level ground. Cutting the excess plastic on the center section cowl trim panel was easy with the tin snips I used and so the whole appearance in the engine bay is very nice. In driving the car I have noticed that the steering response seems a little quicker, although I haven't subjected the car to any high-speed handling stresses yet. Overall, I would rate it as a good buy for anybody who wants to improve the handling performance of their Z. As always, the customer service at Z1 is top notch.
I'm hoping that Z1 will expand its range of chassis stiffening braces. I like their use of triangulation design for greater rigidity.

Fantastic lightweight strut tower brace. Had to cut off some plastic trim at the top to make it fit, but I'm very happy with how it looks.

Replaced the stock 40th AE brace with this one to improve hand access for damping force adjustments, and it helps. This also reduces weight from ~12 lbs to ~5.5 lbs. Fits exactly like the OEM part.
