Newton,
Go to GM Parts Direct: Your direct source for Genuine GM Parts. Enter that part number and it will tell you if its good or not. Also Reeds FAQ has a '03 to '04 CTS Parts List in it. Good luck.

I am looking to buy these to get rid of the nivomats and lower my car with the Eibach springs.

Someone out there has to have done the same thing??

Odysseus(Ody) as he has done it on his '03.

I went to the FE4, CTS-V Nivomats and lowered them with WildWhls spacers. I don't know the part number to the FE2 rear shocks, but the price looks right. Perhaps Dubbed Stealth can confirm the part numbers, or one of the Lindsay Cadillac technicians on this forum.

$160 plus S/H for FE2 rears, or $100 for a takeoff set of FE4's from a V owner and install the 'free' WildWhl spacers. Either option will get the car down with the Eibachs.

I practically stole my FE4s at $40 for all 4

That's to my Pal OldRoadDog.

I paid $120 for my V springs including the S&H. I'm about to call for the installation figures!

Ody, would there be any advantage to replacing all four at once and not just the rears? I want to go with new parts, price isn't the biggest consideration for me. I like knowing that the parts I swap in are new and shouldn't have any hidden problems or rough use on them.

Yes, PLEASE, one of the Caddy dealer persons on the forum if you can confirm the part numbers in this thread that would help me out very much.

How bout some FE4's? I have a set, PM me if interested.

Robert CTS, will the V springs lower the car at all? I was planning on buying new shocks and the eibach springs which should lower it about an inch from what I can tell from the forum posts.

Oysseus told me it should lower my CTS by 1/4" At least I can now tell everyone my ride has been lowered, slammed or dropped!!

My first estimate was $300 for the four wheel installation!!..ouch!

Alignment of the 4 wheels is another $80

A set of 'take-off' FE4's will be as new as it gets other than getting them from GM. Basically, many V owners have the shocks upgraded to FG2's prior to taking delivery of their new cars from the dealer. They put the original FE4's in the trunk. I've yet to hear of a V owner who put the FE4's back on, so they end up sitting in a closet for a year until the owner decide to offer them for recycling on this forum.

The FE2's will be about 25% less firm than the FE4's (basically the same damping rates as the FE3 nimovats, but no self leveling). Eibach will tell you that their springs are designed for use with stock CTS shocks (but not self levling ones). The issue is that the rear spring is the same part in the CTS and CTS-V kits. So which shock is it designed for??????

As far as V springs lowering the CTS, here's the logic I discussed with Robert. A stock V sits about 1/2" lower than a stock CTS, but the V is 300 lbs heavier. That's 75 lbs/spring. The spring rates are 400 lbs/in, which means a CTS will sit somewhere around 0.2" higher on the same springs because of the less weight. 1/2" lower springs plus 0.2" higher because of less weight is about 1/4". The V tires are about 1" taller (1/2" more radius) than the stock CTS 16" or 17" tires, so it may actually end up a little lower than 1/4" lower. Since I know of no one who's done it, they'll be the pathfinder in this. Once we have real numbers, we can compare apples to apples, and not rely on simple assumptions and math, as I have here.

Eibachs will lower your car about 1.2" if you don't have nivomats. With the WildWhl spacers on FE4 shocks, you'll only get about 1" drop in the rear. I wanted to lessen the 'stink bug' look, so I shimmed my front springs up 6mm (about 1/4") to make the drop around 1" front and rear. It sits lower without looking slammed at all. Ground Control says that when they researched ride heights for perfect suspension geometry for handling on the CTS-V, they came up with numbers that translate to fenderwell-to-ground heights of 26 7/8" Front and rear. That's right about where my car sits now.

Using FE2's and no shimming would sit about 1/4" lower than this.

Odysseus, thank you for all of the explanation on this topic. What size are your wheels from your pic? The setup looks great.

Does the 1/4" difference between front and back make it look like a stink bug? I do not know if I would even notice that.

Mannyiac, I got your PM, but I do not have rights to send PM's back. Please send me another with your email and I will be in touch.

I'm running 18"x8" Mille Miglia's with 40mm offset and Bridgestone Potenza 050's in 245/45R18. I wanted to keep the stock sidewall height for ride comfort, but get a larger overall diameter. This is the same size tire/wheel as the CTS-V runs, so I figured if it's the factory size, it's good enough for me!

My car sat ass-end high when I got it. I wanted the rear to lower more than the front, so it sat more even. I was worried that with the WildWhl spacers only allowing 1" lowering in the back, that going -1.2" in the front would only add to my stink-bug look.

I just went out and re-measured my car. It sits at 26 3/4" in the rear and 26 5/8" in the front (ground to fenderwell). If I didn't put the 1/4" spacers in, the front would probably sit almost 1/2" lower than it is (the struts mount about halfway out on the A-arm, so the overall effect would be doubled). Using FE2's in the rear would have dropped it almost 1/4" more out back.

Currently, it has very nice wheel gaps that are constant from the rear, the top, and the front of the tires, with respect to the fenderwells. To me, this is what the sport model should have looked like from the factory.
