Fantastic write up! I will definitely be using this! I just noticed my bushings are worn so it's time for the upgrades!
I love having good excuses to upgrade!

Fantastic thread

Thanks Mango! Are you even still around? Your start of this thread has been a great help to thousands of readers.

But . . . where is the description of Stage 3? I've got a 330xi with 195,000 miles. I've done much of the front, but the car handles like crap. So now, to the rear suspension refresh. I'm going to time this to do it at the same time as a new clutch, which is badly needed. So I'll have the exhaust out, the driveshaft out, and since I want to do RTABs and the differential bushings, I might as well drop the subframe, right? I cannot find any personal DIY of the subframe anywhwere.

I get that I need lots of special presses for all of the rear bushings, I hope to borrow/rent them. But if I look at the ECS package:

http://www.ecstuning.com/BMW-E46-330...its/ES2219643/

I'm going to be dropping the subframe to do the full refresh. So, where's the write-up? Someone must have done this, right?

My 330xi with 195.000 miles is so played out that I've burned up a good set of tires in 20,000 miles. This car needs a lot of work, and if I'm going to spend weeks on my back I'm going to need all the resources I can get.

Can you get your hands on a bentley manual? That would be your best friend. And not just for the suspension, the whole car!

Oh yeah, I have the Bentley manual. The entire description of this process is about as long as: "Remove rear subframe carrier. Press out worn bushings. Reassembly is the reverse of disassembly." I learn a lot more from people who post their experiences here.

Thanks for the info Mango.
I too, am hearing the CLUNK when going over bumps. I'll do a check point on your list & try to do a DIY.
I LOVE my car & the way it rides. just every now & then, I get that roughness on bumps & small holes.

There are usually a couple of those tools for rent, from forum members, in the classified section.

You list the Sport rear shocks up to 9/01 33521095913 and Non-Sport as 33521096366. You have the numbers switched. Also, Tourings use different rear shocks, Sport-33526750784. Non-Sport, 33526750783. M Technik rear shocks are NLA.

No one has mentioned the Z4 M front CABs. They are solid rubber w/an offset for increased steering feel and quicker turn-in (hoping it will help the vague steering common to the E46). They are just like the E30 M3 CABs I run on my 1989 325is, just have to set toe at 0-1/16. Half the cost of Meyle HD also. Anyone running these and can comment?

Sport struts/shocks up to 04/01 were Sachs Advantage. These are much better quality struts than the sport struts from 04/01, which were Sachs Super Touring, their base damper. Sachs Advantage apparently carry a lifetime warranty and go toe to toe with Bilstein HDs, while Super Touring struts carry no such warranty and compare with the Bilstein Touring Class struts.
I question this info. The 9/01 and later prod date cars (330 cars from 4/01 on) actually had stiffer bushings, springs and shocks. Stiffer coupling between steering column and rack, and quicker steering ratio lock-to-lock; 3 vs previous 3.4.

Since the Sachs Advantage has a slightly higher damping rate I'm pretty certain these were paired with the later stiffer springs. I'll check the rear shocks on my Touring w/Sport Package tomorrow and report back.

Again, these are for stock replacements. Some people go aftermarket as the firmer shocks tend to eat at and destroy the stock design as it is too flimsy. I went with Rogue Engineering.

Strut tower reinforcement plates (VITAL--must install!) two per car, part number 51717036781
I'm planning on using going this route with my suspension

http://www.ecstuning.com/BMW-E46-330...oni/ES1876720/

I'm not seeing aftermarket Strut mount on Rogues site...should I use M3 mounts? Also because I am lowering the car do I nee a shorter bump stop?

Slowly peeling though the parts list to see were and what I am going to buy..car has 130k on it now. More questions to come I'm sure.

How much does it cost to do every stage of the refresh? Estimating?

Thanks

This is really really useful. Appreciate the time and effort and detail you have put in to this.

Due to a knackered back (blown and missing disc) I can't do the work myself, but I know a man who can! This will be invaluable so cheers.

V best and happy Christmas, Chris
