How did you like them, and how stiff were they compared to stock? (....and yes, I have searched the archives and the web, but have not been able to find much at all).
I know a lot of people use H&R, but i've heard that they wear out, start to sag and bottom out easily if you have any weight/passengers in the back.
I'm looking for some that are not too stiff b/c my car is a daily driver, but I do want a noticable improvement from stock. I already have the ST swaybars.

Anyone using ST springs? Feel free to post opinions of other
Sorry Lee, I do not have any experience in this matter at all. In fact, I am piggy backing your same question.
1.) Can somebody tell me in plain King's English what springs suck and which ones dont?
2.) Is Intrax a good way to go?
3.) Last, are not shocks more important than springs in the long run, meaning, I can go any brand and just make sure the shocks are Bils or Koni's (some other suggestions)?

Yeah, I've already been through all that site, but those #'s will only tell you so much. A lot of them are only esimates. H & R didn't even know the spring rates of their kit when I called them. They told me that every company measures the rates in different ways, so they don't mean anything.
I called ST and they said that the rates were 151F/192R (lb/in), which is even less than stock in the front, according to m535i.org. Thus I've pretty much given up on all the spring rates and would like to get some other's experiences.
TIA,

I'd have to ask: what is your goal? Lowering? Performance?
I run Dinan springs and Boge Turbo Gas shocks. My car sat a bit high to begin with, so the 3/4"-1" lowering with the Dinans is not that noticeable -- but the difference in handling is. Remember, lowering does not equal increased handling. Some springs lower more, some perform better, and some are good at both. For "both," Spax appears to be good -- about 20% stiffer (as per emails to them a couple of years ago), and moderate lowering.

I'd have to ask: what is your goal? Lowering? Performance?
I'm looking for some of both. I want a nice compromise, nothing too extreme. I would like it a little lower, but I don't want the belly scraping on the ground (maybe ~1" give or take a little). I definately want better performance than stock, but again, nothing too extreme. This is my daily driver, and I don't want something that will shatter my teeth if I hit a rough patch of road. I would just like the thing to be a little more responsive and precise.
The swaybars have helped, but the rest is just too soft, and bouncy in the corners. From most people's comments I believe the Eibach Pro kit is probably a bit stiffer than I want. H&R sounds about right, or just slightly to the stiff side of what I am looking for based on what others say, but I have heard that they wear out, and start to bottom out in the rear easier than others. I think Bavauto would probably be softer than what I am looking for. ST, possibly, but I am worried that they might be a little less in terms of performance than I am looking for as well. When I called they told me their front rates are only 151lb/in which, according to m535i.org, is actually lower than stock.
TIA,
Lee,
I'm also looking into lower and stiffer springs for my daily driver 535i. So far I've ridden in two cars with ST springs with Bilstein Sports. In my opinion, the STs with Bilsteins seemed underdampened, not absorbing road undulations well enough. Fairly nice ride but the Bilsteins felt too stiff for the spring. Spax springs and Bilsteins felt pretty nice to me. Although the Bilsteins I think are a little stiff on compression for the E28 and can send strong jolts through the car on rough roads in combination with 17 inch tires. I've narrowed springs down to Eibach, Spax, and H&Rs. Those three seem to lower the E28 about the same so it is a toss up. With Bilsteins I'd probably go with Spax springs as they felt the best for my tastes, having never tried Eibach or H&R.
I'd like to get some Konis for the struts so I can tune them in a bit for my tastes. But of course this is my opinion on only a couple of rides; I wouldn't mind driving some other E28s to get a feel for other combos before making a decision myself.

I have the BMW M-Technics springs and matching shorter Bilstein M-Technics shocks on my 535is. Reference on the M535i/535is Registry site. I have a set of m5 anti-roll bars that will go on at some point. I'll probably install H & R lowering springs on my 325iC since they make a specific spring kit for the Cabriolet models and it's very conservative in the amount of lowering it does, and is known to be of high quality. Bilstein Sports are the choice for this kit.

I'm confused.... Correct me if i'm wrong, but the above statement seems self-contradicting. If the STs are underdampened with the Bilstein sports, then wouldn't the Bilstein sports be too soft for the STs. If so, which was it, were they under-dampened or were they over-dampened (bilstein SPs being too stiff for the spring).

What affects ride quality more, springs or struts/shocks?
I realize it is probably much more complicated, but am I correct in thinking if I hit a sharp imperfection in the street (like a pothole or a buckle in the street), the struts/shocks would affect the ride more than the spring? Thus ride quality might be a little less harsh with firmer springs and softer struts/shocks, than with softer springs and firmer struts/shocks.

This may make it easier to choose or understand how the springs and shocks/struts work.
The springs hold the vehicle up and will vary the overall height. Spring rate is changed by the length of the spring overall and the materials that make it up.
The shocks/struts dampen the vertical road force.
If you have lower profile tires, this will amplify bumps or with taller tires soften the ride.
I am running 17x8 Milles with 225/45/17s. The ride is rough at low speeds and smooth at higher provided you dont hit potholes and the like. But that is atributed to having lo pros and 17 in wheels. If you have a much taller sidewall and smaller rim, it will be less noticeable because the tire itself will dampen along with the shocks/struts.

Lee,
I'm in the same boat as you - what's the right upgrade for springs and shocks given bad roads and daily driving. I've been angling toward H&Rs with Bilstein Sports. I hadn't heard about the rear end sag problem. I had that issue with my old stock springs a year ago. I swapped on some used struts (stock springs and Bilstein Touring). Better ride with no droopy drawers, but they really aren't doing it for me. I've decided to do it right from the start this spring.
You question about spring effects vs damper effects is interesting and seems to be part of the dark art of suspension design. It's possible to have a combination of springs and shocks that are either over or under damped. If over damped the shocks are dominating and I'm guessing you'd get a harsh ride. If under damped the springs take over and you'd get a lot of bouncing, like when your shocks get old and need replacing.
I'm trying to find the right springs that drop the car about 1 inch. I also prefer the slightly ass-high ride and look over dead flat, or drooping back end. I don't want to go as low as the Eibach or Bavauto springs. It sounds like ST springs may fit the bill. I'll probably make a purchase decision in a month. I'd be interested in knowing what you find and I'll share what I come up with.

I know someone local with a set of ST's he was going to put on his M5. I could ask if he did or is maybe thinking of selling them..?
I think the Bilstein sports (rear) are underdamped fror most sport springs. Mine certainly are with my Eibachs. The fronts, by contrast have tons. On my E34, with adjustable Koni's, I could go from plush to punishing by adjusting rebound, so I would say struts has at least as much (if not significantly more impact on ride than springs). Of course, ideally they are matched, so it is kind of moot.
Underdamped is much more scary for me than overdamped. Sometimes, the damn rear end just wants to take flight mid-corner if I hit a whoop in there somewhere. Frightening!
I dont find the ride with Sports/Eibachs/225/50/16 tires objectionable at all. Pretty nice actually, though a little more rigid after puting in the bars. If you dont have struts already, I would honestly just plunk down for the Dinan setup with revalved Bilsteins and springs. Best handling/riding setup I have ever driven for E28. Very nice!

If your car is stock and you feel that, that means your shocks are totally shot. When you pull them out, I wouldn't be surprised if you can compress them by hand and observe no rebound at all. Check to see if any are leaking visibly.
In your situation, getting new stock parts would make the car feel 100x better. However, you want to lower. I would recommend some of the "softer" lowering springs, like BAS (which are progressive rate) or Dinan, and couple them with either Bilstein HDs (many have reported that the shocks aren't too tall for those springs) or Boge Turbo Gas. That would give you a moderate drop, while retaining a fairly soft ride. The BAS springs will give more compliance in their first 1" or so of travel before stiffening, so initial turn-in may not be as sharp as it would with linear rate springs.
I have RD springs and Koni Yellows. The springs are pretty stiff linear-rate jobs, and while they feel fine on the hwy (comfortable for a 7100-mile road trip last summer, and even my non-car-guy friend didn't find them too rough), on city streets they hurt. They've also introduced some squeaks to the car.
As for ride and damping, you need to take car to match the shock's damping to the springs well, which is why pre-matched kits like the Eibach/Bilstein combos are nice. It took some playing with the Konis to get a ride I like, and even now I feel like I should firm up the rebound on the rear some more (underdamped with a full load).
Risks: If you run a firmer spring with a softer shock, you'll be "underdamped," which means the spring will oscillate and the shock won't be strong enough to dampen the oscillations. Car will feel like a buckboard buggy. You'll get a jackhammer affect over bumps.
If your springs are too soft for the shocks, the car will be "overdamped", so it'll fell nice and tight (if not harsh) going over a bump and there will be little to no rebound in the car's body. The risk here is a process called "jacking down." If the shock's rebound stiffness is so great that the spring can't relax to its native length between compressions, the shock will compress gradually until it is riding on the bump-stops and you will lose all compliance.
The adjustability of Konis makes them a nice choice, because you can play with the rebound firmness (compression is not adjustable) and try to match it to your springs. Others with the same setup can give you an idea of how firm to set the Konis to start.
Good luck,

My OEM rear shocks on the "is" were completely shot, most of the oil was gone and the pistons had mega-clearance on the cylinders. One of them would flop extended just by turning it upside down, the other could be worked by hand.
I bought a set of OEM BMW M-Technics springs for the car which lowered it about .70 inches in the rear and about 1 inch in the front, and to taht I added OEM Bilstein M-Technics shocks. These may not be available now, don't know.

I will say it again for everyone again, H&R are awful , customer service stinks and they absolutely refuse to discuss the shortcomings of their products and for you M5 owners, the rear springs DO NOT WORK

I had not heard that, Steve. The main reason I'd consider them, before your posting this information, was that for my 325i Cabriolet, they're one of the few that make specific springs for it, and the amount of lowering is a pretty conservative 1.2 inches front and 0.70 inches rear. Are their figures unreliable, or are their springs inconsistent?
