Group N Pitch Stop

The STI Group N Pitch Stop Mount is an OEM performance upgrade developed by Subaru Tecnica International to reduce drivetrain movement under acceleration and shifting. Compared to the factory WRX mount, the Group N version uses stiffer rubber bushings, limiting engine pitch (forward/backward movement) during load changes. This results in improved throttle response, more direct power delivery, and noticeably crisper shifts, especially with the 6 speed. It’s a subtle but effective upgrade that enhances drivetrain feel without introducing the harshness of full polyurethane or solid mounts, making it ideal for daily-driven builds. Because it’s an OEM STI part, fitment and reliability are excellent, and it integrates seamlessly with the stock drivetrain setup. Users report the NVH is very minimal and well worth the performance gains.
