So looks like whiteline has a bushing kit for E9x now.
I have been eyeing them for a while now since my bushings are getting tired.
its part # WEK-007
summit racing has it for $319

the only hickup is that it has the rear sub-frame inserts not bushings.
The rear Subframe bushings are #KDT-917 and are $179

Extremely good value!

How would this kit compare to M3 front suspension kit?
I was going to replace only the front with M3 suspension bits but this Whiteline bushing set includes front, rear and subframe. Of course it will require more work but ve been thinking about purchasing a press for a while anyway.
On the side note, subframe inserts are they pretty durable? To last another 70~80k miles? Or should i go with bushings as well?

I can not make sense of first post so not able to give any input, sorry.

Well Whiteline was not offering full rear subframe bushings last time I checked. Only inserts. They are now, and at a pretty decent price:

However this is not included in the full car bushing kit, just the inserts.

As for the M3 bits vs Whiteline bushings in front, I think I'd rather have the M3 bits. Monoball vs poly. But I have an XI and that option is not available for us, the only thing we can do is Strongflex TS bushings (or the $$ one-off monoball bushings can't remember whose) and the lower control arm already has a monoball type bushing.

I would also rather have the M3 bits in the rear that fit instead of pressing poly bushings into non-M3 arms.

This should have been post #1. Thank you for the clarification.

I bought and returned the Whiteline subframe inserts and went with the complete bushings instead. Got them for $175 shipped after a coupon code from here. While the inserts could've been fine, it seemed like the best option was to remove and replace the factory rubber bushing entirely.

For a rwd car, even if you bought the whole-car kit and then also bought the full rear subframe bushing kit to use instead of the inserts, you'd still be spending less on parts than if you bought, say, the M3 front and rear upper control arms. Just a lot more labor pressing all those bushings in to the stock arms.

Since I have an xi, I have the Strongflex front TS bushings.

If at some point I want to redo all the rear control arm stuff, I'd probably go for the 2 upper M3 arms, Megan toe links, Whiteline W63400 kit for the trailing arms, and Whiteline W63401 kit for the camber links. Don't want to mess with switching to M3 shocks with the M3 camber links, since I just bought shocks.

The other option for the front of the xi is Syncro Design, which are very nice looking but also not cheap.

Another interesting thing about these newer whitleine bushings, they are all black instead of yellow,like the subframe inserts were when I bought them a few years ago. I don't know if it means they've gone to a stiffer poly or what.

If you have RWD, get the M3 arms. The wishbone arm will add negative camber and will help reduce understeer.

Poly bushings will just limit arm movement and provide better feedback. They won't affect camber in the front at all unless they are off set.

Google wek-007 its a kit. covers almost the whole car. front and rear.
https://www.summitracing.com/parts/whl-wek007
here are the details
http://www.whiteline.com.au/do_segue...2005-10%2F2011

the kit includes both Front bushings, diff bushings, various rear arms bushings, and rear subframe inserts.
If you want the rear Subframe bushings that are not part of the kit you need KDT-917

https://www.summitracing.com/parts/whl-kdt917

here is more info on that
http://www.whiteline.com.au/product_..._number=kdt917


Hope this clears it up.

If you guys need any help with whiteline we have most of their bushings in stock, readily.

Returning to this topic, installed the M3'vert rear swaybar and r&r'ed the rear arm bushings except for the spring cup arm in my E90. What a b147ch getting these old bushings out, even with pulling tools. Worse cursing fest getting the new ones in.
Even choosing stock factory bushings, serious improvement in ride vs the 130k mile old bushings that came out. Also need to lower the subframe by unbolting it and lower ~ 2 inches using a floor jack under the diff, to get clearance for the swaybar swap.
Predictable yet still eye-opening, how much difference going to that 23.5mm rear bar makes vs the stock (why did BMW even bother putting it in?) 13.5 rear bar the non-M E90's get.
Now planning the biggest mofo job, the rear subframe mounts.
What tool or rig has anyone used to r&r the rear subframe mounts on the E9x?
