Torque Solution Billet Rear Subframe Lockdown Subaru WRX / STI 2015-2021 | TS-SU-232

Helped remove some play in the drivetrain and increased response after having almost all drivetrain bushings and supports you can have. Only missing the center driveshaft carrier now but if feels great.

This part also really shines for cornering. With stiffer sway bars, coilovers, and supporting arms I could tell the rear had a slight delay to fast movements at speed. This removed the delay in turn in in the rear which was nice. I do have a bit more noise but that’s to be expected

I got a 2020 WRX and installed nearly every drive train upgrade you can get for these cars. I got a pitch stop mount, cross member bushings, group n trans mount, rear diff. inserts, drive shaft bushings, you name it. After installing everything, including these, I can 100% say all of the parts put together really stiffened up the entire drive train and made the driving experience (mainly the power delivery) a lot more fun. Since I installed everything together, I can't say for certain these are doing the most work, from what I read, stuff like this product installed alone doesn't do much, but I would highly recommend if you are trying to stiffen everything down. A bit pricey but worth it for my personal goals with the car.
