Default Whiteline Rear Subframe Inserts



http://www.whiteline.com.au/product_..._number=KDT938

Installed these on my 2017 WRX over the weekend (well, all but one missing insert ) and wanted to share a quick review. The primary difference is that the driveline feels more connected with less lash and compliance.

I have previously installed the Perrin Pitch Stop brace, Group N pitch stop, Group N transmission mount, Whiteline transmission crossmember bushings, Perrin Pitch stop, Perrin shifter busing and short shift kit, and Whiteline rear diff inserts. Each of those made shifting feel a bit less vague, and then adding the rear subframe inserts made a surprisingly noticeable contribution to eliminating some of the rubberband feel of shifting.

Little no no increase in NVH.

I'd be lying if I told you that I can instantly feel the car handling better because there's 1 less degree of rear subframe movement on my daily commute. But an autocross and maybe a track day are planned in the future, so we'll see if it makes any noticeable difference in those environments.

How long did the installation take for the inserts . Did you do it or have a Shop do it. Been thinking of doing this one 2.

Did it myself in my garage. Took about 2-3 hours because I had to wiggle the subframe around with a jack to make sure I got a straight shot at all the bolt holes. Didn’t want to risk any cross-threading. It’s totally doable as a home DIY.
