Little help please
I have a bone stock 325IC. I am planning on running ESM011 15x8 et 20 with 205/50/15's.
I want to lower car using 50407 H&R springs, can I keep my stock Sachs struts and shocks with this? I'm still interested as comfortable a ride as possible. Car is strictly a cruiser/DD.
Thanks

Technically you can keep your stock shocks, but it would not be advisable. How low are you looking to go?
Speaking from experience, I can say that my current Ground Control coilover kit is more comfortable than my old H&R/Bilstien combo. My car is also a cruiser, and even with 17" wheels the ride is not at all harsh. It's more expensive, but will get you better results.

Does anyone know the part numbers for the M-Tech 2 vert suspension in north america? Realoem lists 2 different part numbers for the springs, 31331131330 and 31331131333.
However, it lists these as "M-Technic only" for the vert, but doing a part numbers search, it also lists them as being used on a ton of other cars. 325e, etc.
Are the M-Technic springs a myth, with the only difference being the rear sway for the factory upgraded suspension?Drive it hard. Maintain it well.

Eccentrics have been known to go out of adjustment. The weld-in kits can slip as well, but it's less of a problem, you can tack weld the bolt in place once you have the correct alignment dialed in.
There's also the Ireland Engineering Posi-Lock kit that looks promising. It looks a lot harder to arrive at the correct settings, but once you have it set they don't look like they will slip at all.
For any of the RTAB kits, you might need to cut away some of the subframe bushing and modify a wrench so you can reach the adjustment while it's on the car. I aligned mine with the subframe off of the car, wheels installed, and the subframe supported on a block of wood to simulate the ride height of the car. 100% worthwhile mod, but it requires a bit of effort to make it worthwhile. Go enjoy more rear grip and better tire life.Drive it hard. Maintain it well.

Question here regarding a full rear suspension rebuild with all stock rubber parts. I replaced all the bushings in the rear, new shocks, shock mounts, wheel bearings ETC. Did these cars come with some rear camber built in? Mine still has some camber on the rear. I have heard rumors BMW did this for handling?? Is it true??
