GreenFuchs | Underbody braces (6-piece) | GT/GR 86 / BRZ I&II

GreenFuchs Underbody Reinforcement Kit – 6-piece (for Toyota GT86 / GR86 & Subaru BRZ Gen1+2)
More precision, more stability, more control.

Our 6-piece underbody track kit takes your suspension to the next level – specifically designed for the Toyota 86 / Subaru BRZ platform, generation 1 & 2.

What's inside – and what are the benefits?
In front:
– 2x wishbone reinforcements: replace the standard plates – for more direct steering response and better feedback
– 1x main strut behind the engine: massive increase in torsional rigidity in the area of ​​the front axle

Rear:
– 2x axle stiffeners: additional cross-connections for more stability during acceleration
– 1x rear brace behind the bumper: reduces movement in the rearmost part of the vehicle – ideal for sporty driving.

And assembly materials

Why these points in particular?
TRD already demonstrated the effectiveness of targeted underbody reinforcements with their first 86 platform. We're following similar approaches – supplemented by our own practical experience – and achieving a noticeable improvement in driving dynamics. Manufacturers like Hardrace and Cusco also pursue similar stiffening concepts – though often not as a complete solution. And certainly not at this price.

Features:
– 100% compatible with Gen1 (GT86/BRZ 2012–2020) & Gen2 (GR86/BRZ from 2021 onwards)
– Plug & Play installation (partial replacement, partial addition)
– High-strength construction, designed for track day stress
– Compatible with OEM suspension systems, Tein, Flex Z and many more.

Note: The small front reinforcements replace the factory-installed metal plates; all other parts are additionally installed – no permanent modifications are necessary.

Purposeful chassis tuning – for everyone who wants to get more out of their chassis without sacrificing everyday usability.

We also offer the complete suspension kit with front and rear strut braces at a special price! The distinction between Gen1 and Gen2 is only important here for the front strut brace. Otherwise, this option has no effect.

Subject: Registration

Strut braces are not subject to mandatory registration in Germany ( as the nice folks at TÜV SÜD even confirmed to us on Instagram ). However, some inspectors still register them as a precaution; our braces are solidly constructed and in no way inferior to those from other manufacturers. We do not, however, provide a certificate of conformity.

From our perspective, this applies to all stiffening struts, including those for the underbody. If you are unsure, please discuss it with your inspector beforehand. If in doubt, Toyota also provides a certificate for TRD's underbody struts, which demonstrates that no disadvantages are to be expected from additional underbody stiffening. Strength is ensured by the original mounting points, and the material itself is robust. Furthermore, we have now integrated a part number into each component to simplify registration and identification for you.
