Subaru STI Drivetrain Mods Tested — What’s Worth It & What to Skip

After several months of installing drivetrain upgrades on my Subaru STI, I’m ranking every single mod I tested — from the absolute MUST-HAVES to the ones you can probably skip. I’ll cover short shifters & bushings, transmission mounts, rear diff upgrades and more — with my honest opinion, install clips, and positive or negative feedback. If you’re looking to tighten up shift feel, reduce drivetrain slop, and make your STI more responsive without touching the engine, this video will save you time, money, and frustration. 💰 I’ll also share how much all of these mods cost me so you know exactly what you’re getting into. 📌 Mods covered in this video and where to get at best price: SMY Performance Code SMYMike - 10% Off SMY Branded Items (excludes sale and NON SMY items) https://smyperformance.com/?code=MDoz...
