Sharpen your handling and reduce NVH. Follow the development of the Strut Tower Brace here. You've probably read somewhere on the internet that a strut tower brace never does anything but look pretty.

You're about to read otherwise. Armed with a strong background in vehicle dynamics and chassis Design, we've spent months understanding the BRZ/FRS/86 chassis, testing different Designs, collecting data and measuring performance. With the help of the FT86 Club community, we've developed a strut tower brace that works.

Quick Specs

Laser cut, CNC bent brackets ensure perfect fit
Mild steel construction?provides maximum stiffness
Rigid Design prevents unnecessary slop and tolerance stacking
Durable DuPont powdercoat Legal in autocross classes that allow a strut tower bar but no other modification
Installation in minutes with only a single tool
Design Our Design requirements for this project were simple.

The GrimmSpeed Strut Tower Brace must provide additional stiffness between the strut towers, enhancing stability and sharpening steering response. We began with testing both on the street and by statically flexing the chassis in the shop.

Tweaking the chassis manually and using our FARO Arm to plot critical points in CAD, we were able to identify the weak points in the system. What we found was interesting. The OEM triangulation bars actually function very well.

So, while the allure of a beautiful 3-point brace was tempting, the data spoke loud and clear: a simple 2-point brace was the right solution. With that, we set out to create a clean, simple and cost effective solution. Using 3D scanned data from multiple vehicles, we were able to quantify the manufacturing tolerances and Design our brace accordingly.

What that means for you is a perfect fit and easy Installation. 3D-printed prototypes helped speed the development cycle and allowed us to test a number of different bracket Designs for Fitment and aesthetics. One key Design decision was to utilize a rigid, welded construction. The reasons for this are three-fold, but what it boils down to is the old standby, ??Keep It Simple, Stupid'.

When the goal is to reduce compliance in the system, it's Not hard to understand why a solid form Design is best. A rigid bar will function with maximum stiffness, providing the Best possible performance? A multi-piece bar adds unnecessary cost and complexity to a fundamentally simple mechanism

A multi-piece bar adds additional welding and hardware, stacking tolerances and creating many possible failure modes

Materials End brackets are laser cut from 3/16 steel and precision CNC bent. These brackets were sized to provide maximum strength and stiffness without compromising thread engagement with the vehicle. Cross tubes are CNC laser cut to length from . 125in wall tubing.

Mild steel, being both the viable material that is both economical as well as the well-suited for the job, was an easy choice. Contrary to popular belief, mild steel offers greater stiffness than Stainless Steel and while Stainless Steel offers higher yield strength, in this particular application, we're nowhere near those types of forces.

The assemblies are all robotically welded in the same fixture for unbeatable accuracy and repeatability. Each finished brace is coated with a durable DuPont textured powdercoating. The cherry on top, so to speak, is that we've laser cut the GS logos from Stainless Steel, so you're free to polish the coating off of it for a unique look without worry about rust.

Performance Performance metrics, both quantitative and qualitative were carefully tracked through development and following production. In our slalom testing, peak deflection between the strut towers dropped from . 180in to . 030in, a decrease of 83. 3 Percent.

Even more Not able than the lowering of deflection was the substantial decrease in noise' within the data. You can truly feel this improvement the first time you leave your driveway after the Install. Expect an immediate and Not iceable decrease in NVH and a Not iceable increase in sharpness and steering feel. What you see is that without the brace, the data shows a great deal of noise and unpredictable deflection, indicating an unsettled chassis.

After Installation of the brace, noise in the data is greatly decreased and behavior is much more predictable. With the brace Installed, the chassis reacts as you would expect, cycling between tension and compression as the brace works to maintain stiffness between the strut towers through the slalom. Customer Reviews WOW! Im usually very skeptical and I thought this was more of an engine bay dress up piece but Nope.

The moment you drive off your home and hit the streets you can already feel it. The car is more planted, nimble, quieter Over bumps and less jarring. The car also feels more responsive. Whether this is a placebo effect or Not , I have no regrets.

SliverBrz So, after Installing this and driving to work today, got to say. . . . . It is awesome. If i were to start all over, or even just to recommend to a new twin owner, make this your first purchase. Amazing how much better the car feels, as someone else mentioned, steering feels tighter, less play, just solid. Great purchase! gdrider77 Your comment on how it improved ride was one of the things that helped sell me.

It really is true. I took my test drive this morning. On a BRZ with stock suspension and tires, it has removed a LOT of the harshness. Driveways, intersections, bumps, potholes are much smoother and less Not iceable now. It seems to handle cornering better but I was limited by school zones being checked out.

The strut tower brace is really a plus to my driving satisfaction. elrod I am Not the handiest of men, but even for my skill level this was like a 10m Install where 4m was trying to find my socket set. And what a difference in ride/handling. It makes one wonder why this wasn't Included from the factory.

Optimus Prime I agree! The Install was very easy and the car drives and feels better! This was one of the Best upgrades I have done to the BRZ and the Redbar looks awesome! tripjammer Install took all of about 10 minutes. Really liking the difference the bar makes.

Overall, a tighter feel in the steering wheel, the minor back and forth I felt via the steering wheel, even on pretty level roads, is gone. I'm feeling quite a bit of difference (IMHO) when driving Over washboard roads or small bumps.

Thanks GS! PNW FRS
