After 100k miles my stock rear bushing was torn about 70% Installed these in addition to the STI rearend on my WRX. Now I know it wont tear and no slop in rear drivetrain. no feeling of any harshness or noise. takes a specific puller to reach in the tight area of the subframe

Replacement of stock factory Slop bushings is necessary for those in the 400+ power range, you will not be disappointed, and the drivetrain feels way more precise. Power to the ground ftw.

These work as advertised, and make a noticeable difference in drive line lash. However, be sure you are ordering the right kit! There are inserts that you can put in easily, and then there are these, which for me anyways, required dropping the entire subframe, and taking it to a machine shop with a bearing press to get the old ones out and the new ones in. Not worth the hassle. Next time I would just buy the inserts. This info is not apparent when you order. Heads up.

these bushing are MUCH stiffer than stock! i absolutely love them! compared to the stock ones(gum) these are better looking, stiffer, and allow for powa to go to the wheels instead of flexing like the stock ones do. p.s. i sudjest that if you are going to install these bushings you also do the subframe bushings, sway bars, and endlinks since you will need to remove those parts to put these bushing in. it will also help a ton and will probably save you 2-3 hours of work if you have a press! RSD's costumer service is unbeatable!

A: Whiteline states the inserts are about 80% the stiffness of the full urethane replacements. The difference is there but not everyone would be able to tell.

A: The stock bushings will need to be pressed out which is why alot of guys will opt for the KDT903 kit which are the inserts and a bit easier to install.

A: The difference would be that this would completely replace the stock bushing, where the insert will just fill the voids in the OE bushing.
