ok i have a 2005 cadillac sts with FE1 rear suspension, i bought B&G lowering springs and the front sits nice and so does the rear but my problem is that when the car is still or sitting awhile it sits even but when im driving the car and i stop wherever i am going the rear for some reason raises up like if it has air suspension and it looks factory height in the rear. but if i have FE1 rear shocks shouldnt it not be raising up the car?

They all have ELC (except maybe the V?). FE1/FE2/FE3..... can be thought of as soft ride/sport ride, sportier as the number increases. Different spring rates, shocks/struts, sway bars...

You'll have to shorten the connecting rods on the ride height sensors to "fool" the ELC system.

where are the right height sensors located? and where and what are the connecting rods? i also tried looking for ELC fuses and my car doesnt have any at all.

The sensors are in the wheel wells, the connecting rods connect them to the control arms. Not positive on the '05+ cars, but you may only have one with your passive suspension.

Wrong.

Only F55 have air ride.

Others have nivomat shocks which pump up and level out while driving.

Spacers are needed to fix this D3 sold them.

I had the same problem & D3 won't sell you the shock hats by themselves if you didn't buy the springs from them. I took my rear shocks back out & removed the hats on them. There is approximately a 1.5 inch thick rubber spacer on top of the shock. I sliced it down to about a 1/4 inch thick & reinstalled. Problem solved.

This is just how I did it, I'm not saying that its the best or the right way but it worked & I don't have any issues.

P.S. From what I was able to find online for images of the D3 part. It looks like that is what they did. Removed the rubber spacer & replaced it with a shortened one.

how easy is it to remove the shock? cause when its sitting and the car hasnt moved the rear wheel well is even with the top of the tire no gap or finger space and i have stock 17" rims with 235/50/17 tires and once the car is in motion and i stop somewhere the rear lifts up and from having no gap or finger space it ends up having a 2 finger gap. the front is fine its just the rear.

It's not too bad to pull the shocks. You have to get the car off the ground & let the rear suspension hang. There are 2 nuts inside the trunk on top of each shock & there is 1 bolt on the bottom that attaches the shock to the control arm.

do i have to disassemble the whole back arms to get the shock out? and do i have to worry about it having pressure or shooting out? and about how long does it take to take off?

No you don't have to disassemble the whole thing & it does not have pressure like the coil spring. It shouldn't take more than an hour per side total.

cool thanks man how exactly did you trim it down what did you use?

I actually had a band saw in the shop, but if u put it in a vice you can do it with a hacksaw. Just take your time so u get it nice & straight.

Here's a pic of mine.

this is how mine looked when i had it on 22s with no drop at all just stock height.

I think I read here a while back that there are actually two leveling systems. If the 'gray-matter' serves, only one uses rods for sensing.

You'll have to shorten the connecting rods on the ride height sensors to "fool" the ELC system.

how do you shorten the rods btw?

MoistCabbage
05-23-13, 07:03 PM
I was mistaken when I posted they all have ELC. But on vehicles that do have it, one way is to buy threaded rod at a hardware store, of the correct diameter to fit into the plastic rod ends on the original rods, and cut it to your desired length. Then just thread the rod ends on.

yo whats up man if you can call me up i have a question about the bushing of the shock 786-859-7772

hey i looked for the sensors but i have no idea what they look like or where exactly they are i took the tires off both rear and looked for sensors but i dont see anything at all. do you have any picture of what they look like or exactly where they are located?

When you take the tire of the are obvious they have little rods connected to the upper control arm the are a rotary switch, also they need to longer if you want it to sit lower.

ive looked and honestly i dont see no rods at all i would need to see a picture of somebodys 2005+ sts rear suspension and where its located cause i cannot see or find it at all i dont know what it looks like.

if you have nivomat shocks there wont be rods. the shocks the self are set to a pre determined height all you can do is raise the top mounting position by cutting the bushing on top.

ive been researching online and the sts with FE1 suspension doesnt come with the leveling shocks so i dont understand what can be making my rear shocks lift back up. ive checked for an air compressor and i dont have one ive checked the rear shocks for airlines or for any lines feeding to the shocks and they dont have any. im so lost i do not understand what is going on.

that looks like what im going to have to end up doing. but what i dont understand is why when the car is off and sits over night the rear sits where its suppose to be sitting but once i start driving it will raise the car.

You don't have ELC.

After the car sits overnight, it's at the WRONG ride height. Once the car is driven, and you go over a few bumps, the shocks "pump" back up.

so the only option is to shave the bushing down on the top of the shock then from the looks of it

Yes motion of the car going over bumps causes the shocks to "pump up" think of it like a bicycle pump built it to the shock
