Looking to elevate the handling of your Gen 4 Mazda 3 Hatch to new levels? If that is the case then you may be interested in the new CorkSport Rear Hatch Brace. The 4th GEN Mazda 3 Rear Hatch Brace (aka Rear Strut Brace) is designed for any 2019+ Mazda 3 Hatchback Turbo & non-Turbo model and is a must-have for those wanting to improve chassis stiffness. If you already have CorkSport’s Front Tower Bar, Rear Motor Mount, or Rear Sway Bar installed, this will be the perfect complement for your 2019+ Mazda 3 Hatchback.
We actually introduced this back in April 2023 with a Tech Blog that you can check out here. Now here is the final product!
The Need For A Rear Hatch Brace
First, let’s start by addressing why the CS Mazda 3 Rear Hatch Brace is only available for the hatch and not the sedan as well. One of the main benefits of a hatch is that you get ~50% more cargo area than what the sedan offers. This makes it very practical for day-to-day use and road trips but does come with some tradeoffs. The one that is most relevant to us as car enthusiasts is the removal of the support structure that is behind the rear seats. This support structure helps the chassis to better resist flexing and twisting. Since this support structure is missing in the hatch, it results in lower performance when comparing chassis rigidity. This is where the CorkSport Rear Hatch Brace comes into play and leads to an increase in the torsional rigidity of your Mazda 3 hatch, so you get even better handling characteristics
The Mazda 3 Rear Hatch Brace Has 2 Configurations
Available in two configurations, you can choose just how aggressive of a setup you want. Even if you start with the Stage 1, you can always upgrade to the Stage 2 down the road and carry over the parts you already have. Below we’ll get into more specifics of why you should consider picking up the CorkSport Rear Hatch Brace for your Mazda 3 Hatch.
Stage 1 – Single Top Cross-Bar
Stage 2 – Top Cross-bar with Triangulate Lower Bars & Lower Mount
The Components of the RHB
The CorkSport RHB is made up of two main types of components, the first being the brackets and the other the cross bar/s. The brackets are made out of 3/16in thick carbon steel so the cross bars have a rock-solid base to mount to. The cross bars on the other hand are made from 0.083in wall rectangular carbon steel tubing to provide a strong connection between the brackets. Both brackets and the crossbar get powder coated in textured black to provide a look that will blend in with the interior to give you an OEM look and feel.
Functional and Stylish Hardware
Connecting everything is stainless steel hardware, but not just your boring hex head bolts. Being a centerpiece of your hatchback, we wanted the hardware to not just be functional, but look great. To do that we used countersink head screws with conical washers to give a clean and purposeful look to the CS Rear Hatch Brace and your Mazda 3 Turbo.
