For anyone looking to pick up Koni Sports, if you call Race Consulting Agency, you can talk them down some on price. They quoted me $550 shipped for all 4...

8741-1390RSPORT - Front right
8741-1390LSPORT - Front left
2x 8040-1271SPORT - Rear shocks

I ended up buying just the fronts from them for $360 shipped because I found the rears on closeout from a company on eBay for $68 each. But it was their last two.

Also I found bushing/mount prices to be best at FCPeuro. I bought Lemforder front strut mounts and M3Z4 RTAB's with a poly limiting kit. Total cost for all parts was $108 with free shipping - much less than I expected.

Hope this helps!

Thanks for the heads up. Koni usually has their sale starting in March which is when Race Consulting had the deal of $500 shipped for a full set of Koni Yellow.

Does the lower pinch bolt for the struts have to come out all the way?

No it does not

It does not, but I did. When I did pretty much this same suspension refresh on my sister's 330Xi, I broke down and bought an electric impact wrench. Made the job go so much quicker, well worth the investment IMO.

Hmm...so it could've been finished. We had too much trouble with the bolt on one side, so decided to just do the rear and buy an impact gun. I also ordered these bolts:

Part# 31306779487

I think these are the right ones. They were a bit rusty.

Those should be the ones, according to realoem.com:

I ordered 2 front sway bar links. Mechanic noted one of the boots was broken. part# 31356780847

@BMWCurves - I went through your parts list on post#1 and I see that for the rear suspension, you only replaced the RTABs. Any reason you did not replace the outer upper and lower ball joints?

- Upper ball joint: Where the upper control arm connects to the trailing arm
- Lower ball joint: Where the lower control arm connects to the trailing arm

Just curious as to why only the RTABs.
