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%. Even more notable 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. GrimmSpeed Strut Tower Brace Subaru BRZ /Scion FRS /Toyota GT86 expect an immediate and noticeable decrease in NVH and a noticeable increase in sharpness and steering feel. The chart below shows strut tower deflection through a series of slalom turns before and after the installation of the GrimmSpeed Strut Tower Brace. 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.
