Has anyone installed the Whiteline KDT924 yet?

Keen to know what it does i can't tell from the whiteline pictures.

I haven't installed them, but pretty sure they're diff mount bushings?

They are not available yet in the USA.

They replace the entire rear deferential mounts.

The two black mounts in the rear subframe seen here.

It's suppose to prevent some movement in the rear diff, this movement results in a negligible amount of drive train loss. I know the 2008–2010 WRX rear diff movement was so bad you could feel and hear it hit the bottom of the car under heavy acceleration. I had these (well white line diff inserts) on both my 2009 and my 2011 WRX, the 09 needed them the 11 didn't.

My advice is, unless you notice a large about of shift in the drive train while accelerating (other than in the transmission), I'd avoid these. What you gain isn't worth the increase in NVH

id install the rear cross member bushings before doing these

The other option is the KDT925 kit. This is an insert kit like the KDT922 subframe inserts for both the front and rear diff bushes. Not as solid as complete bush replacements but generally a much better NVH tradeoff (and if they aren't they're easy to remove). These are meant to be shipping within a couple of weeks.

Yeah I have a set of KDT922 waiting to go in. I was thinking if these were worth while improvment I was going to hold off installing KDT922 and install both at the same time. It sounds like I might just go an install the KDT922's and wait further reviews of KDT924's

Thanks for all your feedback.

Now to just wait for the whiteline LCAs

Yes installed KDT924 today ( INSERTS).

Full review shortly.

I've had KDT922 and KDT925 for the last few months.
Can't say I really noticed the crossmember inserts but the diff inserts are very noticeable.
With all diff inserts installed I found the cluncking from the driveline was too loud and was worried about placing extra shock loads on the drivetrain.
After testing different combos I found that if I installed the inserts on 2 of the 4 bushes it was a good compromise.
