Hey about your noise question, I thought about it some more and really dont think it's the struts because I recall the noise doesn't occur when I go over a bump or dip that is equivalent across both front wheels - it's only the irregular L to R bumps that induce noise. Which is why I suspect the sway endlinks and/or loose bracketry.
End links very well could be shot. I destroyed mine really quickly and had a nice noise up front for a bit. I have TMS adjustables waiting to go on in spring

Were yours stock end links? What mileage did they go bad at?

Sorry, just saw this.

Mine were stock end links. Lowered on a 28mm bar.

I installed coilovers at 12,000 miles and I'm not at 38,000 miles. They were shot well before now

Hmmm, mine might be too. Once it stops snowing I will put it up on a rack and check everything. Thanks

Okay, I'll be generic and ask:

My stock suspension is going out - a shock is actually leaking. Instead of forcing the replacement under CPO, I'm considering doing a full suspension workup. Well, by which I mean springs/shocks.

I come from the EM and FD world, so I've dealt with front and rear drive cars, both econoboxes and real sports cars (in a way the E92 won't ever be *cough*pig*cough*). My understanding has always been that the only advantage of coilovers over regular springs was adjustability - you can raise and lower your car by adjusting the coilovers. After all, aren't coilovers just springs in an adjustable compression perch? Adjustable shocks are something that is separate from your spring decision.

What do I want?

I want a daily drivable car (on mediocre roads, Austin's no winner on the public works side).
I want reduced float at high speeds (135+).
I want slightly tighter feel in the steering.
I want a car I can autocross (half a dozen times a year, tops).
I want a car I can do an occasional track day in (a few times a year).
Most importantly, I want minimal ride quality sacrifice.

Money isn't that important a factor, but obviously matters - I've no desire to pay $1,000 more for a 5% increase in handling.

I'm currently on stock sport wheels with runflats (yeah, I know, but there's a story and it's kinda hilarious, but in short when I get ready to buy new tires I inevitably receive a pair of new runflats for $75). I intend to move to a 19" wheel with similarly profiled tire, and I recognize that the smaller profile will cost me ride quality, but I like the look enough to make the sacrifice.

To put it in perspective, my goal is 500whp - I have an FMIC and a chargepipe/BOV in the trunk (in addition to the Cobb, ardesign catted downpipe, and BMS DCI already installed), and once they're installed I'll be doing a protune with Wedge. That's the extent of my power goals for a long while. I have another FD to buy, after all.

So what do you think, fellas?

I would go with something proven and simple without a huge drop... Like eibach pro kits and koni yellows.

You need shocks made for lowering springs. Get Bilstein B8 or Koni Yellow.

Honestly, nothing. I'm eyeing this combo though:

ECS Tuning Suspension Refresh kit with M3 front and rear control arms



http://www.ecstuning.com/BMW-E92-335...its/ES2601977/


E92 335i Coupe Bilstein B12 Pro-Kit Sport Suspension Package

http://www.turnermotorsport.com/p-22...n-package.aspx

I figure at 83k on the odometer, I need the bushings and such anyway, so it's an opportune time to step it up. I've just been holding off the purchase because not only is it nearly $3k in parts, labor will be another grand or two.

I still haven't installed my FMIC, either.

Which would perform better under "heavy load" such as 3+ people and a trunk full of luggage:

Koni FSD
Bilstein B8

My issue is that I have rear 15mm spacers, and even AFTER rolling fenders, I get some tire rub in the back on bouncy highway bumps. So I know my rear shocks/struts are compromised.

I also want "cornering performance" and it's a daily driver, no track usage. I also don't want a harsh, bumpy ride.

Torn between the promise of the "comfort" of the FSD, but the horror stories of them losing their effectiveness after 15K-20K miles, and the worry that the B8 will be "too stiff" for DD comfort.

HALP !!!

Heavily loaded and wanting more compression dampening?

There's no question, Bilstein B6 or B8 all the way. 1000% for sure. That's what they're known for.

While I'd do it all at once, you can always just start by swapping in the rear shocks quickly, see if you like how they feel. That's like a $200 outlay, and if you think they give too much road feel, you can always sell them on here for near what you paid.

You do need to make considerations though. The only way you're going to reduce the rubbing in the rear over bumps is an increase in compression dampening over stock. That's going to result in a (slightly) firmer ride. There's simply no way around it.

Thanks much. So would this look like my shopping list to completely refresh the rear struts:

Two B8 Rear Sport Shock, Mfg Part #24-120425
One Monroe 907984 Strut-Mate Mounting Kit (I assume the kit has two?)
BMW Subframe Bushing Insert Kit Rear - Whiteline KDT918

Does that look correct? Anything else? Thanks much.

You'd need two rear kits. That being said, if you're not looking to make things any firmer back there, maybe stick with the stock foam mounts?

I've run the whiteline inserts and they made a noticeable improvement in rear stability.

That being said, if it's not a money thing, the install time is close enough between inserts and full replacements that you should just go with the KDT917 two-piece polys.

Both require lowering the subframe about the same amount, the bushings just require a few extra minutes to press the old ones out with a $10 hand-held propane torch, a large socket and some creative jack work.

When you say I need "two rear kits" do you mean the Monroe, or the WhiteLine, or both?

I think I do want to replace the foam mounts, because although I don't want SEVERE additional firmness, there is also "highway speed bounce" in the rear I need to eliminate. the Monroe mounts should help alleviate that, right?
Thanks.
