: I'm looking to raise the rear end...

It's low because the air bags have been removed to help it launch, I'm fairly sure the springs are stock, I'll get some pics up once it's back from the shop. The exhaust is run underneath the custom subframe connectors and is 2inches from the ground. I have banged it a couple times.
I don't know where the air bags mount or if the space has been taken by the subframe connectors, but I'm looking into coilovers. I'm thinking ground control because I have stock shocks that I can use with them.

Can the ground controls raise the car? How much? If not, what do you recommend?

I would love to level the car out, I'm hoping to raise the rear an inch or so and lower the front an inch or so, I enjoy suspension modifications...

What kind of car are you talking about? :confused: There aren't any air bags in the CTS-V's suspension. And with the exhaust running down the center of the car under the driveshaft I don't see how subframe connectors could get in the way.

No? The shop that built the connectors told me he removed them. He also sent me some pics before I Bought the car. I tried to upload them last night, but they were too large. I'll try to resize them and get them posted.
I remember reading about an auto leveling system, I figured it was controlled by a pump and air.

This is the 2004-2007 CTS-V forum. What kind of car do you have?

No air bags on our cars. The shocks are self leveling. Do more research before working on the car. Not trying to sound like I'm putting you down. Just don't want you to get hurt or mess something up.

Either he doesn't know what he's talking about, or some previous owner made some significant / interesting modifications to the car.

I'd be interested in seeing some pics of the subframe connectors. Where do they route? I still don't understand how typical SFCs would get in the way of the normal exhaust routing. :confused:

The rear shocks are Nivomat shocks. I think this link - www.cadillacfaq.com/faq/answers/pdf/nivomat.pdf - should have info, although I'm having trouble getting it to open here at work.

Before you go changing anything I would recommend figuring out what's on the car now. If the car has stock springs and shocks, then the rear shouldn't be low unless something is broken (or the springs have been cut, which takes us back to the previous owner's interesting modifications).

On a level surface, what are the ride heights at the front and rear of the car? (Measure from the center of the wheel straight up to the fender lip.)

Is that a 9 inch diff and 3 inch pipes? This car has had some SERIOUS mods done. Take this car to the best tuner/performance shop you can find. Don't let a regular mechanic mess anything up. You may be sitting on a high-end build there.

Edit-- i don't even recognize the sub-frame.

Thanks! That's a C3 diff. with richmond 390s. The car is at Late Model Throttle in Waukesha WI. The "O" in throttle is of a GM 6spd shifter knob, They love their LSXs, I'm glad I found them. It is a big build, the guy I bought it from told me that it was the fastest 1st gen up until about a year ago, and told me to look it up on dragtimes.com, but I couldn't find it.

Oh, the car is at the shop because I had a collapsed lifter, He is taking the IAT out of the airbox and putting it into the manifold. And adding a place to fill the intercooler. And then up the boost a bit and dyno tune. It's only a Maggie 112, but I'm thinking 10-12lbs will put down 600+

Here is a link to a little more about the car, like you can't find it on the first page lol, but anyways:

Here is a pic of the stock shocks (along with another pair). Have the stock shocks been modified? I think when I get the car back, I'll put them in and snap a couple more pics so that you can see exactly as it sits.

The blue ones are QA1 shocks. The stock ones look stock except the QA1s look tiny in comparison.

So I could very well put the stock ones back in and that would raise the rear up?

Without knowing what dampers are on the car now it's hard to say what installing the stockers will do. However, it seems to me re-installing the stock bits would be the logical thing to do - that way you'd be starting from a known combination.

If you were to install an aftermarket shock with the stock springs, might that lower the car? The PO never stated the springs to have been changed, only the shocks. I'm not familiar with struts that change ride height though...

----------

And the QA1s, are they supposed to change the ride height?

AAIIIC

A strut can affect ride height to a little bit, but a shock shouldn't. In either case, the springs are mainly responsible for the ride height. But since you've got a very different rear end, my suggestion is to go back to stock with the dampers and the springs to see where you stand. If the ride height (which we still don't know, as we have no pictures or measurements to go by) is too low, then the springs aren't stock (or are stockers that have been cut).

The original thread on this car http://www.cadillacforums.com/forums/2004-2007-cadillac-cts-v-general/284959-i-bought-one.html said it had adjustable drag shocks. That typically means a set 90/10 (70/30 or 60/40) shocks up front and a set of 50/50 shocks in the rear, all to facilitate weight transfer. If the rears are stock, and the fronts are QA1s, the fronts may conceivably be "drag shocks."

carsaremytoys

The fronts are the QA1s, what is on the rear atm is unknown. I don't have any spare springs, but I'll get pics to you guys as soon as I get the car back.

Car is still at the shop, progress is being made, but in the meantime I am doing some research. The GC kit sounds pretty good, not sure what spring rates yet, or what shocks I'll use, but I found the a good price on the kit here:

I'm a little concerned about the maker of the CTS-V though... lol
