Product Description

Armed with a strong background in vehicle dynamics and chassis design, GrimmSpeed has spent countless hours understanding the BRZ/FR-S chassis, testing different designs, collecting data and measuring performance. GrimmSpeed has developed a strut tower brace that works for the BRZ/FRS.

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

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 .125 in 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 powder coating.

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 .180 in to .030 in, a decrease of 83.3%. Even more notable than the lowering of deflection was the substantial decrease in 'noise' within the data. Users can truly feel this improvement the first time they leave their driveway after the install. They can expect an immediate and noticeable decrease in NVH and a noticeable increase in sharpness and steering feel.
