We got the emails and the phone calls. You want D3 STS-V Sport Lowering Springs for your Cadillac. We are happy to announce we have started another production run for the Cadillac STS-V and STS application. Limited quantities will be produced, so please make sure you get your order in ASAP. STS/STS-V sport lowering springs will be available for shipping and installation early September. Please contact your local D3 authorized retailer or sales rep to ensure you get a set of sport springs before they are all gone.
I was looking at my car today and the gap between wheel and fender bothers me way too much especially in the rear. I want to pick up 1 of the 2 sets left on eBay I hope I get the money together in time before they're gone. Waiting to put tires/brakes/ and possibly rotors. Wanna do it in one big sweep but springs and rotors are still waiting to be purchased. (Non MRC STS)
EDIT: if any of you stsv guys who just upgraded springs still have your stock springs I may be interested in them shoot me a pm.

To say the car drives and looks as it probably should have straight from the factory is an absolutely understatement. Just drove home on the D3 springs and new Conti extreme contact DWS. Car drives and handles excellent. Still absolutely comfortable. As a matter of fact the guy who did the work said he was surprised how good the ride was after the installation. He expected it to be much more jarring. The change is noticeable though, especially in its composure handling curves. I'm very happy. Car looks a little better but I understand there is still a while to go before they set in.
I'm planning on doing a wash, clay, wax next weekend to prepare for winter so I'll snap a few pics.
So I call d3 and order the spring they says will ship out on tuesday, I'm going to put new strut on it. I have a idea of getting my cv7 wheels extended to 10 inch, it will cost about 350 a wheel. Do yall think it should fit.

Hows the clearance clarence? Is it too low or are you happy with the height? I scrape pulling forward into to most ramps now I'm worried I might destroy my bumper if I'm .75 lower it sure would look good and the sportier handling from stock sts to these springs must be amazing. Was an alignment required after install the springs? Because I have tires and brakes waiting to be put on but I was waiting for possibility of getting these springs
So far no issues with the clearance but I drove from the place and back. About 5 miles. The clearance will surely get worse as the springs set in. I've said this in the past, I'm worried about when I move back to ny. It's gonna be a uhaul with flatbed and I'm afraid of scraping on the bottom. Not so much in the front because I can always add some wood to make the grade less steep, but between the front and rear wheels. When my fronts get to the top of the incline, will the bottom scrape before the rear tires get high enough? Don't forget, it's 3/4 inch up front, but 1 1/4 in the back.

Scroll down a little on that page and you'll get a visual of what I'm talking about in case I'm not being clear.
Alignment.. Yes you need to get an alignment. Not only that, but you want the alignment checked 4-6 months after you install them due to the springs setting in. And then once more about a year after you install them.
I am happy with the ride height but let's just say I look forward to it settling down a little more.
Just washed my car by the way and at 5'7" I'm having a much easier time reaching the middle of the roof.
Funny thing is the lowered height accentuates the fact that you can definitely fit wider rims in these wells. No plans for that though. I'm looking at blue calipers next.
Factory spring rates are 400lbs up front and 380 out back.
D3 makes it 525.412 up front and 496.857 in the back.
That equates to +125.412 lbs front and +116.857 rear, about 32% and 33%, respectively.
All that info is courtesy of Dr. Design on another post about the springs, back in March of 2009.
That being said, how does competitive driving mode work when it stiffens the ride? Does it electronically increase the spring rates? If so by how much? Anyone know this info?
Ah. So damping ratio, or coefficient is quantifiable, yes? If so how does comp driving mode damping compare to damping when not in comp driving mode. Anyone know this?
I know for the F55 magnetic ride sts switching between touring and sport suspension modes changes the viscosity of the magneto fluid thus giving a softer vs sportier ride and handling capabilities. I am unsure how the V series shocks function. It amazes me they did not get magnaride.
Started on my car at about 6:30 last night. Wash, dry, clay bar, swirl remover, wax. Got done at 3:50 in the morning. Glad it's all over. I did tire shine too. I usually don't since it's pretty much a waste with all the brake dust, but I knew I would be taking pics. Took these a couple of hours ago. Some real nice shots. Car has been on the D3 springs for 6 days now. Enjoy.

Just picked up the last set off eBay can't wait to get them. Wish it wasn't below freezing so I can actually get some fun back road driving in once I install them.
No replacement of the strut here although I kind of anticipate the ones I have on now going out a little premature versus if I didn't put the lowering springs on.
Did you install yourself? I plan on putting mine in tomorrow with a friend. How long did it take? And those rubber pieces that came with them where does the large think rubber stoppers go and where does the thin ones with washers go?
I'm thinking the thin rubber spacer went below the upper shock mount, above the plastic cover, and that both rubber spacers (one factory & one aftermarket each side, stacked) , went on top of the mount with the newly provided metal washer under the nut?
Took my ride to dealer had them check a noise coming from the front suspension and a oil leak. This what they told me valve cover gaskets and on the front suspension need upper control arm bracket.
Those gaskets leak on mine also. I believe they are only like 8 ft lbs on the screws. Some of them are a bit hard to get to.. But all of mine were loose. Good luck with your service
The noise on the front got worse as it got colder in Texas I heard occasionally in summer it really annoying. Can't really described the noise but u hear it over the bumps. The bracket they are talking about is above the upper control arm it has a bushings on the top of it. I think, so I order the bracket it part of the upper control arm assembly. I thought I need strut guess not. Anyway got my springs n I bought new strut and the upper control arm. Next Saturday will install it and the valve cover gaskets. I took a picture but can't display it for y'all.
So I installed my springs Thursday night wasn't too bad, the rears are small and not really crazy about how they are totally free if you jack up the rear end (even though it made installation easy)
First impression: wheel gap is gone and looks great! Handling has noticeable improvements and you can feel that it is quite a bit stiffer but not uncomfortable. Looking around the car the rear "appears" lower than the front but I think the large front fenders and more subtle rear fenders make it look like rear is lower now that they are a lot closer to be level than rear being higher.
I also notice the front and rear had extra negative camber and hoped the alignment I got on Saturday would fix that. Well it didn't and I plan on going back this week to see what I can do to get 0 camber. You guys who already got springs on and aligned any help? Do you still have negative camber? It looks more than it should be and I just put fresh tires on and I would rather not wear them out prematurely
