Subaru BRZ & Scion FR-S Strut Tower Brace From Grimmspeed
Posted on 04 September 2013
We've all read that strut tower braces doesn't do anything except look pretty. You are about to learn that this is an internet myth. The Grimmspeed team is armed with a thorough background in overall vehicle dynamics and chassis setup / design. The GrimmSpeed team has spent the last several months understanding the Subaru BRZ & Scion FR-S chassis, real world testing of different designs, collecting useable data and measuring street and track performance. With this insight GrimmSpeed has recently developed a front strut tower brace that works for the BRZ & FRS platforms.
- Precision Laser Cut, CNC bent brackets ensure a perfect fit and finish
- Steel construction to provide superior stiffness
- A rigid design prevents unnecessary slop & tolerance stacking
- DuPont Powdercoat finish available in Black or Red
- Legal in auto-x classes where a strut tower bar is allowed but no other modification
- Installation is easy and takes only minutes with one single tool
The end brackets are laser-cut from 3/16 thick steel and precision bent. Mounting brackets were designed to provide the maximum strength and stiffness while not compromising thread engagement on the car. Cross-tubes are CNC laser cut from .125" wall tubing. Mild-steel, is both economical and the most well suited for this job, was an easy choice. Contrary to popular belief, mild offers greater stiffness than stainless and while stainless steel does offer higher strength, for this particular application, we are nowhere near the type of force that would require SS. The strut tower bar assemblies are robotically tig welded in the exact same fixture for increased accuracy and repeatability. Each finished strut tower brace is powdercoated with a durable DuPont finish!
In slalom testing, peak deflection between our BRZ strut towers dropped from .180" to .030", a decrease of 83.3%! Owners can feel this improvement the very first time they leave their driveway post install. You can expect an immediate and noticeable decrease in NVH and a noticeable increase in sharpness and overall steering feel.
