Hey everyone. I know a lot of people had asked to see pictures after I put my UUC front springs on.

Here is a comparison of the stock spring next to the UUC.

I LOVE these springs. They lowered the car perfectly. And on top of that, they honest to God have the exact same ride as the OEM springs while cruising, but have firmed up the ride around corners. One thing that surprised me was how the car remains perfectly flat now during braking, the nose doesn't dive. I keep forgetting the springs are different, they ride so well. My old H&R springs on my last 750 would crash over EVERY bump and expansion joint. if anything, I would wager to say the ride is better than OEM with these springs.

I only lowered the front, as I like that look. If you are looking for springs that maintain ride quality but give a "moderate" drop (aka not slammed to the ground) then UUC is the way to go.

I also did a little mini-mod today.

I've been waiting forever for this install!! It's the perfect drop.

Hmmm so if I think about it, installing these would make my M Sport have the plushness of a non sport, but handle better than the sport? Do you know how they compare to an M Sport setup?

These springs sound perfect.

I have only driven a "true" Sport once or twice and it was brief so I can't really compare. But compared to my old springs, these ones ride just as well if not better (and I got rid of an annoying "clunk" by replacing all my spring pads in the process.)

One thing that surprised me was how the car remains perfectly flat now during braking, the nose doesn't dive.

these 2 are contradicting statements.....

Which is it?

You can't keep the same "ride" because the "ride" is characterized by the damping ratio...By changing your spring rate, you change it by definition...If spring rate is firmed up, damping ratio is changed

Z = c / (2*√(k*m))
Z - damping ratio (dimensionless unit)
c - damping
m - mass
k - spring rate

ah..good ole spring theory

if anything, I would wager to say the ride is better than OEM with these springs.
On the flipside, this is entirely possible because the damping ratio may not have been optimized for your personal taste by BMW engineers. Design is all about compromise....unless you spend crap tons of money....which actually is part of the compromise picture :D

The springs are "progressive" springs, which means they will firm up more when compressed than an ideal spring. What board is saying is plausible.

Nice! I have been trying to figure out how to improve my suspension to get the level of comfort I want. My springs, shocks are original and probably need to be replaced (car only has 50k miles). But I am careful as I want a sport ride, I probably need to lower it but I don't want to lose any passenger comfort. I currently ride with 16" wheels/tires as I prefer my passengers not to feel every vibration in the road.

Yeah they are progressive. And everything I had read about progressive springs seems to speak to what I was saying earlier.

http://www.tuninglinx.com/html/suspension-springs.html
"Progressive springs are likely "all-in one" solutions. Progressive springs are often used on performance aftermarket kits like Eibach or others, and they are good for daily performance street driving. They help you achieve the highest performance when driving hard, while providing a smooth, comfortable drive the rest of the time."

http://www.4wheelonline.com/superlift_springs.htm
"Most coil springs have rates that are constant; if it takes 400 pounds to compress the spring the first one inch, another 400 pounds will compress it the second inch, and so on. With a progressive rate coil, the initial couple of inches of compression requires less rate than the remainder of compression. This improves your "Sunday drive" ride quality, yet rate increase when you're in "Banzi mode".

http://www.tsxclub.com/forums/1st-gen-suspension/3597-straight-linear-vs-progressive-rate-springs-road-use-knowledge.html
"The majority want it to be a comfortable and relaxed ride but as soon as a twisty road is spotted again, the attention changes to the need for a firm, planted feel with lots of driving feedback from the tires. In a corner, the increased load causes the car to ‘squat’, meaning the suspension gets compressed both front and rear. Because of this compression, the initial comfortable springs stiffen up and start giving you the planted feel and feedback. And the faster you drive, the more feedback and feel will the springs give you, exactly as our race car example but for a road car application."

I've got the H&R 2"/0.5" lowering springs, and the height looks pretty much the same (at first sight anyway), but the H&R's are coil shaped, and not "spherically" shaped like your's (and the stock springs). Not that I'm any kind of an expert on this matter, but because of this, your's look softer than the H&R's. If that is correct, I'd really consider replacing the H&R's with the UUC springs, if that gives me closer to stock ride. The H&R's aren't bad in any way, but they do stiffen things ever so slightly, and the extra small vibrations/"road noise" I got after replacing the stock with H&R's really annoy me.

Have you noticed anything like this on your car?

I had H&R Stage 1 on my previous 750 and I always disliked the ride afterwards. I always felt the "thwack thwack" as I went over expansion joints with my H&R. It looked great, so I lived with it.

These UUC springs are much better. They are highly comparable with the stock ride, at least while cruising. I often forget that I have lowered the car and need to remind myself to slow down a bit for speedbumps. That was the biggest thing I was surprised about on the drive home after installing them.

After getting over the fear that I forgot some tighten something and a wheel was about to fly off, I realized "Dang, this feels exactly the same as when I drove to the shop."

I should have my UUC springs in a day or 2... With the rears, I wonder if any adjustment to the self leveling regulating valve is needed in addition to installing the new springs

noodlesandsam

01-21-2013, 02:35 PM

I'd do the install, and see where the rear settles.

The adjustment for the sls height is a sensor clamped onto the rear swaybar. The position of this determines the 'level' height.

Be careful messing with this. There are instructions available online. You don't want to be under 2 tons of car, and move that the wrong way without having the proper points supported.

Is this DIY, or are you having someone do this?

In e38.org, there is a sls valve height adjustment thread under the suspension heading.

ANYONE who has SLS should read this, about how it can bite you. No one was hurt, but it was close. This is not a system for noobs to play with. A couple of bucks is not worth the worst possible outcome.

Thanks for the input. It is a bit of both actually.. I own my own automotive workshop. I had an E32 with SLS which I had to adjust after major repairs to the system. Was just wondering if adjustment was needed on the E38 after installing lowering springs.
I think adjustment would be required as if not, the sls would just pump the shocks back up to stock ride height.

We would adjust it while the car was on top of an inspection it and the workmen were safely inside the pit. Even if the car coms crashing down onto the floor, no one inside the pit gets affected at all.

If you have a pit, that is a good start. Still, be careful out there.

The photos I posted in the OP were taken with my iPhone 4s. These were taken with my Nikon. I think it shows the stance a little better, since the black body of the car and the black tires got kind of washed out on the iPhone photos.

The photos are over half their original size so sorry the quality isn't the greatest.

Enjoy!

I went out and measured my sport today and it came in at 27 3/4". So if my memory served me correctly, the UUC springs are 1" lower than the sport springs and still give a good ride.

Thanks to Board57796 and everyone who advised on this.

I have seen many threads out there with folks wanting to know if an E38 740 etc with SLS and EDC can be lowered while retaining both those features and I have seen many replies to the negative.

Well thanks to all of your advice, I can now prove that it can indeed be done.. as I have.

Unlike board57796, I have installed both front and rear lowering springs on my 740iL and adjusted the rear SLS just right so that it lowers the car and still levels the car when the rear is loaded.
All 4 wheels have 12mm spacers and that seems to be about the maximum spacer thickness usable at the rear. I will try
15mm and see but with the 12mm it is very very close

Thanks for the lovely compliments everyone !!

Here are the answers to all your questions...

Although they are not original to my car, these are stock option wheels and tires..
Front 8JX18 ET:20 with 235/50ZR18
Rear 9JX18 ET:22 with 255/45ZR18

They feel absolutely perfect !!! We have VERY bad roads here in Sri Lanka with lots of pot holes and ripples on the road.
Even in those conditions, the car is so soft and smooth. No bumping and bouncing very very nice indeed. I would go as far as saying better than the stock springs !!

psjr I would love to show you the interior of the car with the rear monitor although I don't know where I should post the pics.

shanecarmaster1

03-17-2013, 11:41 AM

I'm glad you're happy! I'm wondering which shocks are most compatible with the UUC springs because lowering springs kill shocks, yet they work well with EDC. I wonder if it would have the same effect on Sport package shocks.

chanaka

03-17-2013, 12:01 PM

Technically there is absolutely no way lowering springs can kill shocks. Practically what happens is... Shocks which have been used for a while on the car, tends to be worn out slightly in the section it has been riding on. Then when you lower the car and that portion of rod the shock rides on changes, the slight rough and uneven portion which now rides on the seals, causes the seals to fail.

If like me, you install new shocks, then you will have absolutely no problem what ever the type of shock it is

03-19-2013, 09:17 PM

Is it me or does the back look to low? The gap between the tire and the wheel well is actually bigger in the front? Even in stock installation this is the case. I got B&G springs and Bilstein sport shocks. Will try to install next month when I get back to florida. I wish B&G spared another 1/2" in the rear so the stance looked right from the side.

Geez I'm still waiting on mine. I ordered them late jan early feb n was just told they r on back order. I wish UUC would've told me this when ordering. Oh in case anyone is wondering the springs r made by B&G.

chanaka n board ur e38s are very classy examples. It's what I want mine to be like. Happy motoring!

Yeah, unfortunately I think the easiest way to order these springs is directly through B&G. I feel bad because I recommended these springs but I have heard SO many people ask me about their long shipping time. It really is crazy. I just thought mine was a fluke, I actually had to call and tell the person on the phone at UUC that I was going to dispute the charge on my CC, because I could never get a tracking number or any info as to when my springs would arrive. It's unfortunate though, since they are a board sponsor I believe and I would have preferred everyone go through them. But buying directly from the source seems to be the best option. I was told that essentially B&G shipped the springs to UUC, which were then delivered to "the wrong warehouse" and sat until I continued to call and try to find them :(

Every time I tried to email to get some sort of written confirmation, the email would get kicked back and would say that the only way to get a response from UUC was to call. I will say, though, that the people on the phone were very friendly. It's just a bummer it took so long to get mine, and is taking others even longer.

I need to get some commission from UUC for this thread :devillook. Thank you for the nice words. Obviously, if you order the springs, it comes with front and rear. I just decided to keep them stock for now. I like the look of the front just slightly lower than the rear.

Does the car have different body roll with the drop only in the front? I don't think there is 1.4" in the rear of space. If you put the rear in won't it look like it were slammed and causing rubbing?

I am considering this as well. Listening to you is making me think about doing this but for some reason I would think that BMW would plan so much around the way the car sits and everything that I am scared to mess with the driving dynamics. Normally I thought you drop both front and rear so it won't affect the steering geometry etc.

I am ordering B&G set too as soon as they come back in stock. But I am starting to have second thoughts about lowering the front end only, I am worried if it ruin anything. I really love my BMW and I do hate the gap in between the tire and the fender in the front. But I thought BMW engineers were so thorough especially with the E38 that I am worried if I am going to mess something up.

:eyecrazy Seriously?! I'm going to have to go look at the box mine came in!

The Lesjofors website also says "Lowering springs are finished in black and packed in attractive retail packaging" but all the pictures I have seen of springs ordered from UUC are red (which is what B&G springs are finished in.)

Do what makes you happiest, but I will say that my car only feels better, even with just having the front springs installed. I haven't felt a need to install the rears, although I am sure I will eventually just to have new springs back there.

I'm curios. Are 750 S-EDC springs different to say the M-Sport Springs? Basically, would M-Sport springs work on an S-EDC strut?

Actually, I am 95% sure that was a car I was looking to buy, before I found the one I ended up with. It also had UUC springs, and had a V12 badge below the door trim line, and was located in Washington state with around 95,000 miles on it.

The owner (private at that time) was not great at responding to texts, so I found the one I have now and bought it instead. And with less miles.

EDIT TO ADD: In fact it is the same car. I remember because I google'd the VIN and a thread from 2005 came up with the car for sale. http://forums.bimmerforums.com/forum/showthread.php?367012-2001-750iL-Sport-Black-on-Black-20-s-UUC-Tint Asking $48,000.

I believe so. There are 740i Sports with S-EDC, right?

I used to see that car around from time to time. I made a complement to the driver of it once a few years back and his response was something along the lines of "thanks, I'm borrowing it from a friend"

I mean Springs from an E38 M-Sport without S-EDC. Would they work on a 750 with S-EDC? Just the fronts.

I was wondering the same thing. I have a spare set of front EDC struts & springs that I'm waiting to put on my 750, and would like to lower the front a little. Wondering if the 740i sport springs would accomplish that...

They certainly would. Just a subtle drop.

Sweet! That's really all I'm looking for. Any guess as to how much of a drop it would be?

TIS says about 3/4" front, none rear.

Thanks...I think that should be enough. I'm only planning on dropping the front so that will be perfect.

Hello,

I have a bmw e38 728i non sport, that for me the suspension was to soft.
For one year am riding with H&R Stage 1 and bilstein b4. I think this setup is not bad, but i feel the front of the car is harder than the rear.
Thats the reason i start seaching the spring rates, and i was studying this theme for some time.
After reading this forum and talking with eibach and H&R i can show you results i have. I dont want this study to be a total 100% correct but more an approximation.

Bmw non sport around F 146 lbs / R 161 lbs
Bmw Sport around F 161 lbs / R 190 lbs
UCC around F 161 lbs / R 176 lbs
Eibach around F 171 lbs / R 200 lbs
H&R stage 1 around F 200 lbs / R 171 lbs
H&R stage 2 around F 286 lbs / R 257 lbs

UCC are more or less the same as bmw sport, maybe a little soft in the rear.
Eibach have more 5 or 6% in front and rear than bmw sport.
H&R stage 1 have 25% in front and less 12% in rear than bmw sport.

This is totally different from what Bmw wanted for the e38 design from factory.
Maybe H&R its a good balance for track with rear anti roll bar, i dont know. I am just a normal street driver.
To my understanding, if you want something similar to bmw sport stay with UCC or Eibach.
I could be totally wrong.

PS. Nowadays i cant find UCC springs in any store.
And Eibach are announced for the v8 and v12. But i know some guys who instaled in their 728i with good results,
just the front doenst lower so much. I think i will try Eibach.
