I don’t why there aren’t more reviews for this kit. This is hands down one of the most satisfying upgrades I’ve done. 1st & 2nd gear shift lurching/jerking is gone. The car feels like it’s gliding on butter and all around feels more stable and predictable. There are no down sides to these. One of the best bang for your buck kits out there. As long as you have some decent mechanical know how these aren’t that bad to install. Do yourself a favor and get this kit. I have spoken.
This will not fit with Forester SH9 Body. This is for SH5 body. For SH9 you have to get the same with 2011 Sti part number #WHI KDT910.
I installed this kit a few days ago in my stage two GRB chassis sti and what a difference! Short of the sway bars, this has been the most profound difference I have felt in the way the car handles. Dramatic and positive change in how the car behaves in corners. NVH was negligible, Would highly recommend this to anyone looking to tighten up feel of their car.
Very nice upgrade. You only realize when putting these in that the entire rear end of the car is hanging on by four rubber bushings that can deflect around. Install was not too bad and the car feels solid and crisp now. There isn't any real vibration that I can notice. Very nice! 9/10 would bang.
Easy to install if you are reasonably competent, these are a new MUST DO product on my list for WRX owners. It really allows the rear end to plant, especially under acceleration. Stupid cheap and awesome... best $55 ever spent I would say.

A: This is confirmed for the 2011 2.5i, these will work along with the KDT903 and will have benefits in locking down the subframe from moving.

A: Yes, this kit is confirmed to fit on the 2011 Impreza wagon and sedan N/A. This kit is designed to minimize the play/slop in the subframe under aggressive driving and would supply a noticeable improvement in rear end traction when combined with the KDT903 kit.

Q: fitment dkolo88183978 years ago
Will this fit in tandem with the perrin subframe lock down bushings?

A: Essentially the perrin subframe lock down bushings are the same thing as this kit. But this whiteline kit would be stiffer and more secure. The perrin kit just sits on top of the mount as these actually lock into place on the mount.
