Anyone know where these two kits go?

One set presses into the rear subframe to replace the crap factory bushes (with the voids) that are really sloppy. The mounting studs in the rear diff go through these bushes to hold it to the subframe.

The other set replace the outer bushes in the "T" bar (or outrigger) which is the front part of the rear diff mount. They sit right near the inner side of sills just in front of the rear wheels. (the part on the right of the pic below)

funky - pics added for clarity.

Awesome thanks guys.

So I\'m guessing if you replaced the outrigger bushes with hard ones, the whiteline kit below is redundant?

hmmm hard to know, you would potentially make it redundant yes, but also might not hurt having both if you wanted it super tough / hard / firm.

not replaced either of those from factory though so unknown on their results alone or in tandem.

Yeah, you dont really need those ones if you replace the whole bush. The factory bushes move a lot, and that is the main cause of the sometimes loud "thump" when you change gears. Fitting either those spacers, or the full replacement bushes solves that problem.

You should definitely consider changing them - there is a lot of movement in the factory bushes (expecially old worn original ones) that it gets quite noticable when pushing the car through corners.

I found replacing these makes the rear of the car feel a lot more direct and positive.
