Reddit reviews PERRIN Solid Shifter Bushing Compatible with Subaru WRX 2015 - 19

Just start with the Rocky Spring Shift Stop and Perrin Brass Bushing.The rocky spring is the same as perrin shift stop just cheaper.

I installed both the SS and Bushing in my 18 lmtd in under 30 minutes. It cleaned it up a lot. Install both of those for under $50 and then reevaluate before you go replacing the entire thing.

I also have the short throw shifter from factory.

I recommend both the shift stop mentioned above + the Perrin brash shifter bushing ( https://www.amazon.com/Perrin-Subaru-Speed-Shifter-Bushing/dp/B019D8NQD2 ). There are a ton of great DIY installs for both of these products mentioned above. The stop does help with going vertical, by tightening up its gate horizontally. The stop keeps you in-line with the gate and makes the shifter have a more secure path into 1st, 2nd, 5th, & 6th. The brash bushing will relive a lot of that notchiness and slop and will help you slide into gear with more ease.

I got both the bushing and shift stop from Amazon due to prime and cheaper price.

The Invidia R400 is louder at cold starts and its a deep sound. At idle, it sounds stock. Below 2.5k rpm is not too loud and but does get louder at higher rpms. I do love the deep bass sound. I typically try to shift below 3k rpm when leaving my Apt community in the morning. Wife says her 18 Stock Mustang 5.0 is still louder :/
