Whiteline Rear Differential Mount Inserts Subaru WRX 08-26 / STI 08-21 / Forester XT 09-18 | KDT903

Great small upgrade , worth the money

If your car is brand new, these won't feel like anything has changed but also will not make the car feel sloppy down the line.

If your car feels off, these will make it feel like fresh from the dealer.

This is a no brainer. Just do it. You can feel a direct connection from the throttle to the power at the wheels. No more lag in getting the car moving. Drastically more responsive.

For information purposes. 26k miles on my car. I installed on ramps and supported the rear diff with a small jack just in case. Still had to poke with a razor blade to get the rear diff inserts to go in partially, then torqued down the rest of the way in. For the brace inserts I was able to wiggle the brace back in, then smacked it with the palm of my hand most of the way, but had to use my other jack to get the inserts side the final couple cms. All in all about an hour between going to my desk to work then back outside to work on it.

This is one of a couple upgrades I did to my 16 WRX and let me tell you. The differential is more stable and you can feel more the car when you are accelerating. I totally recommend this parts

Did this before other mounts, there’s a noticeable difference when shifting and especially when starting from a stop. The carrier inserts are a bit of a pain. Keep in mind they only go in on one side. You’ll probably need to use a jack to press it back in, take your time. I didn’t have to drop my exhaust but it would’ve made things easier.

Easy install

Not too challenging, can do it with two jacks and or one and a jack stand. Just need to be able to jack the differential up a little to get the forward brace off. Not sure if I can tell a difference with the other drive train stuff I’ve put on but can’t go wrong with white line

definitely makes a difference. Car feels tighter, more responsive. little added nvh, mostly heard on decel. worth the tradeoff.

These mounts are super easy to install and give you the piece of mind when your driving a subaru how it should be driven; fast! I had great customer service from Dane, and got my package earlier than expected.

I’ve used these on several of my builds and god do I love them, they remove a ton of slip out of the drivetrain so shifting feels more crisp, starting from a stop is way smoother engagement and you don’t need to press in new bushings to get an immense effect. Well done!
