View Full Version : Has anyone cut there B&G S2 Springs to lower the STS (06) furtherÉ

08-23-12, 11:48 PM
Thinking of getting B&G Springs to lower my 2006 sts, but I want more drop (much more than 1.6 inches). I want a drop of around 5 or 6 inches in the back and 2 inches from the front. Has anyone cut their B&G springs for a further drop, and what other complications are involved in such a drop (shocks, fender, alignment, etc.)

Well to drop this car 5-6 inches you are going to have to do alot more than just cut drop coils! Rememember if you cut to much then the spring will be loose in the front struts and wont work! I have a buddy who wanted to slam his car Way beyond coil overs and he made his own struts and has spent hours lifting the motor so he dident blow through oil pans! But anyways back on topic I think maybe a set of coil overs on the front and for the rear get a set of springs made for the application! What are you going to run for wheels becaus this is going to be a big issue! I'm verry interested in where this is going and would low to see some pictures of this in progress let's start slamming these scars and btw does yours have magnetic ride control?

For now I am going to be keeping the stock wheels that come with the 2006 STS, I wanted to lower my car with the dimensions stated above. For the rear, isnt it possible to get B&G Springs and trim them further to lower the ride height. The B&G are springs made for lowering STSs but its just not close to enough. I dont think mines is MRC. The front doesnt bother me too much but i want to get the back down to a point the car is either leveled or pitched only a little.

If i could get my car as low as the pic above I would be satisfied. But with original rims ofcourse. (hope i uploaded the pic properly). I found the pic online.

9650696506 Heres a quick picture i whipped up (from a STS outline) to demonstrate what I want to accomplish. compared to the previous picture posted, this is a little lower and much more desirable.

Not trying to be a dick, but CUTTING SPRINGS ON A CADILLAC STS??? How fast do you want to blow your struts?

Unless there is an aftermarket coil over kit for these cars, you are a proper lemon if you think you can safely lower the car without modifying the suspension heavily. Cutting springs on stock struts holding up a pig of a car is insane. Ride quality will be worse than awful and at any given time, your struts will blow.

Granted, I haven't researched after market suspensions for an STS, but again, unless there is an aftermarket kit which included adjustable coil overs and control arms, you're going to have to build your own.

I have done a lot of custom work with Bilstein. You send them your CAD designs, they will build it -- or you can build them yourself with the experience. I've done custom suspensions on a wide variety of makes and models and would be willing to help, but I will say this first: You're looking around $5k minimum for a custom built suspension.

Source: Two of the few I built myself. Both static, but the S8 is on Accuair E-level at the moment.



*edit* After finding there is basically nothing in terms of coil overs or even a more aggressive strut/spring combo, I'm a little bit terrified about how some of you are riding around lowered.

yeah i have searched for lowering stuff for this car and have not been sucessfull btw ever thought about air? do you have any more information on that one you posted about like what he had? btw cutting springs is not desirable because it changes the spring rate of the spring, which makes your ride verry bouncy. also increases the chances of a broken spring. and to cut a spring from a 1.6 inch lowering spring to like a 6 inch lowering spring would be insane not smart really you will jsut be waisting the spring and you will have to get new ones.

If your car has leveling, you'll have to disable it in the chassis computer to lower the back more than the front. Just removing pr disconnecting it, will produce errors.

sigh, this sucks, so what is the best way to lower an STS? please post you opinions and answers. I went to a near by suspension shop and they told me to throw in lowering springs from another car (guy said impala, cts, etc) and make them fit or whip up a quick bracket/adapter. Not sure how qualified this mechanic was....

are the D3 lowering springs good? also looking to lower on 20"s, I don't want it slammed but I need to cut out the gap between the back wheel well and the tires. D3 is back ordered tho

I believe on the v forum a member made brackets to use v1 CTS coil overs on a v. Assuming you don't have f55 you could use them if not when you unplug the f55 struts you'll be speed limited to 90.

fak it, im just gunna grab lowering springs made for another car that are close to the geometry of STS springs.

I see this turning out very poorly.

Let us know when your shocks blow.

Got off the phone with a buddy at AccuAir on Friday. They can build an e-level setup for non MRC RWD STS with touch pad for $5k. Installation is a different story.

Non mrc is the key

Personally I love the mrc handling especially with the addition of V sway bars.

Dittos on MRC.

Good luck on the mods. Post your results!

5-6" on the back shit that's a lot!!!! I have the drop springs on my sts an it sits about an 1 inch from the rear tire 275/45/20.. An it still rides good like a caddy should, i do have the self leveling shocks witch i want to replace with regular ones but I can't find them anywhere!! I would like it lower but there ain't really shit to lower these cars... Unless u go with airbags but that would be a lot of money
