: Lowering Springs

06-25-13, 09:48 PM
So I bought new 20" wheels and tires and now there is too much of a gap between the fender and tire. I would like to lower the car between an 1"-1.5" I have been looking around for the lowering springs and nobody has them. Is there another way to lower the car? Can you cut the factory springs? Will lowering springs from a CTS-V work on our car? Any help would be appreciated.

Lowering springs are no longer available so cutting the stock ones is the only option. I would start out with a half coil on the front and go from there. You don't want to go too far obviously. Do the front first then match the back. You'll probably have to cut the spring a few times each. Use a cut off wheel, not a torch. The ride with get a little stiffer but it will do that with lowering springs too.

You also have to make a spacer for the rear shocks so they stay approximately the same length as stock. Otherwise they will auto-extend themselves as you drive and your car will look silly. Do a google search of this forum for some info about that.

Cts gen 2 springs have tested on an sts by a member and bolted right on. I would assume the v springs would work fine as well.

You might be able to find the B&G 10.1.003 which was the part number, but D3 had the exclusive as I was informed, but a simple search shows them in stock a few places online, unknown if they are actually available. You would still need to fab up a spacer for the rear shocks. I was waiting and waiting for D3 to get them back in stock, they have been backordered for like a year, and I believe they have discontinued them now.

I did that exact search. I found the same links you did with the B&G springs "in stock". I even placed an order and payed with Paypal. A couple hours later I received an email saying "sorry, they are no longer available" and I got a refund. I called one of the other sites before I placed an order and found out the same thing. As a last resort, I contacted D3 too. I haven't heard back from them.

I would love to hear from someone who actually used CTS springs to lower their STS. Otherwise I guess I will have to start cutting.

Ok guys I have some updates and more info that may help those that want to lower there sts or sts-v. Again all my info is based off my own car so you experience may vary a bit.

Cts gen 2 springs will work and have been working well in my car there are four types of springs that I have info on

STS stock Front 364 lbs linear rear 388 linear (estimated based on 15 less stiff than STS-V)
STS-V stock Front 428 lbs linear Rear 456lbs linear
1. stock cts-v springs Front -0.650 rear +0.350 400lbs linear front and rear from what I can tell
2. Eibach cts-v sedan springs Front -1.250 400-457lbs progressive rear -0.750 (or 1.375 one coil cut) 331-605lbs progressive
3. Eibach cts-v coupe springs Front -1.875 400-457lbs progressive rear -1.375 (one rear coil cut) 331-605lbs progressive
4. Eibach cts v6 springs Front -1.875 400-514lbs progressive rear -1.375 (one rear coil cut) 274-582lbs progressive (what I run)

Notes:
-front bump stops must be cut!, If you don't expect a bounce squeaky ride.
-Cut the bump stops at the first convolution.
-I used anti seize in the bump stop between the foam and metal collar to prevent and squeaks. (I have no squeaks)
-If you have air bags or MRC you must lengthen your ride height rods front and rear.
-Currently I added 3/8 to the front and 5/8 to the rear.
-If nothing is done to the rear the air bags will lift the car back to near stock
-If nothing is done to the front it will throw a "service suspension" code, the front shocks freak out and groin then go in to limp mode (softest setting)
-If you have Nivomat rear shocks You need to modify the mounting point of the shock an amount equal to the expected drop to keep them from pumping back up (I have no more info on how to cause I don't have those shocks sorry)

I'd buy your stock v springs if you go aftermarket.

Still hunting for those I see. What does a new set run?

Like $400. Not horrible but not worth it for that. I don't want lower. Just stiffer.

I haven't done anything yet but I'm leaning towards cutting the stock springs.

What would it take to get B&G / D3 to do a small run of springs?
How many?
How much?

I have been waiting for D3 to get more for almost a year now, so I would be in for a set.

If you have been waiting for a year, I would say they aren't going to make any more. I contacted them about the springs and they never even responded. This just backs up all of the horror stories I have read about D3 on this forum.

I'm leaning towards the Gen 2 CTS-V springs, perhaps the Eibachs? The thought of having my stock springs laying around seems like a good idea.

Hammerhead, are you trying to lower your car too? How much will the cts-v springs lower an sts-v? Or do they need to be cut also?

hammerheadv
07-03-13, 04:28 PM
Yes, I want to lower my car just a bit. I haven't done any thorough research yet, but I'm hoping for 1"-1.5" with an aftermarket kit.

Thats exactly what I want to do. I don't mind cutting the factory springs because I'm not looking to save them and stockpile parts. I already have the stock intake taking up space in my basement and someday the factory exhaust.

I have staggered 22's on my car with an Extremely Aggresive rear wheel & tire combo. I actually took the D3 springs out because they weren't low enough & I cut my stocks 1 1/2 coils on all 4 corners about a month ago. I have No issues as far as squeaks or rattles. Of course it is slightly stiffer but that's ok. I usually drive it like I stole it anyway.

I am a little concerned with cutting the springs... I would have thought that the ride would be much softer, yet everyone mentions the ride is stiffer.

Unfortunately, I don't have any pics of the actual spring cutting process but its Definately not Nuclear Physics!! Lol

The silver STS has the B&G lowering springs and the black STS (mine) has the stock springs (uncut). Its a little hard to see the difference because the car is black but I can tell you that it looks much better lowered.

I think the ride quality is fine, not too different from when it was stock. I Do Not have magnetic ride. But I have my mom in the car fairly regularly & she's used to her 96 Fleetwood Brougham. She doesn't complain so it can't be bad!!! Lol

Is there a difference between the sts and the sts v springs? As I want to lower my 06 sts v and wouldn't care if I had to cut the springs

Just trying to understand the numbers from professor_speed's post:


Eibach cts-v sedan springs Front -1.250 400-457lbs progressive rear -0.750 (or 1.375 one coil cut) 331-605lbs progressive

Does that mean the CTSV2 sedan springs theoretically will lower an STSV 1.25" in the front, and 1.374" in the rear?

Also, does anyone have any info/tuts on making spacers for Nivomat rears? If D3 would sell just the spacers, would they work with these spring applications (at least to the specified drop of their own springs).

Sorry I don't come here much. sts and sts-v are said to be a different rates, The rates I gave are based on the differences in percentages given.
I couldn't obtain actual values but those should be pretty close.

ctsv2 "should drop 1.250 front and .750 rear or if you cut one coil 1.375 rear.
