With Subaru’s MacPherson strut design, the vehicles entire vertical suspension load is transmitted to the top of the vehicle's strut tower. For this reason there is inherent flex within the strut towers relative to the vehicle body. During performance driving there is enough flex to alter what should be static camber, toe, and caster settings. This change can make steering response and body roll more pronounced and unpredictable.
The PERRIN Performance strut tower brace solves this problem. During cornering, the PERRIN strut brace transfers the load of each strut tower via tension and compression of the strut bar to the opposing strut tower. This reduces flex by sharing the load and tying the strut towers together. The improved chassis rigidity enhances steering precision under high load conditions and reduces understeer. Tire wear and metal fatigue in the strut tower area can be reduced.
Utilizing heat-treated cast aluminum feet and mandrel bent, thin wall 4130 Cro-moly tubing, the PERRIN bar is strong while remaining lightweight.
The strut bar is powder coated for protection against the elements.
- 2005-2009 Legacy GT customers will need to trim plastic engine cover.
- It will press tight against the firewall plastic on the 2014-2016 Forester & Forester XT.

quick and easy install, fit perfectly and was a great addition. I got mine custom powder coated which was just the cherry on top! I'm still working on the engine bay but so far 10/10
Fit perfectly on my 2020 Subaru STI Limited. Just had to relocate my IAG Street Series AOS down a little. And looks awesome.
The Perrin strut brace is excellent but had to remove when I installed the AOS :-(
