Perrin Driveshaft Lockdown Subaru WRX / STI 2008-2025 | PSP-DRV-201

Installation was definitely within an hour from jacking up the car. Aligning the front and back piece to volt on was the hardest part but went in quite well.

The feeling is what the car should have come with. It still has a give since I did not do the driveshaft carrier since that may give a nvh. The feel is more like putting on the group N pitch stop rather than the harder pitchstop.

Great product.

Great product makes a huge difference on the shifting jumps.

Not a huge difference but I'm sure it helps some. Pretty easy install.

This plus the carrier bearing kit removes a lot of the slop the system sees on torque, or on throttle lift. Feels like there’s less bucking happening now.

Easy install, noticeable improvement, takes all the unnecessary movement out of the differential , highly recommend

Added this on top of my driveshaft center support bushings and it smoothed out my gear shifts especially shifting from 1st to 2nd. Great addition!

Simple mod to get just a little more power to the wheels. Fit like a glove.

Fit great, makes a tremendous difference in shifts and solidifying the drivetrain!

Part is great and it is the second one I bought since completing my sti 6 speed swap!

Great
