    lowering advice on my 86 brougham?

    This spring, I would like to lower my 86 brougham. I have used 9C1 rear springs that I was going to install, but have been thinking about just buying some new SS springs for all 4 corners and lowering it since I've been advised by both my dad and my mechanic to replace the front springs as well as the rears (due to the car having blown shocks for 15+ years). I was wondering if I decide to use SS springs instead of stock height springs, will I have to do anything to the front to compensate for the shorter ride height? What would I have to do to make the springs fit and keep the tires from being tilted inwards? Is it just as easy as installing the new springs and getting an alignment?
    Also, does anyone have photos of their lowered brougham to give me an idea of how these look on SS springs?

    Re: lowering advice on my 86 brougham?

    Jamco makes springs wound for specific amount of drop. A year or so ago their web site showed a 70-80's era Deville, with the available 1-3 inch drop. I just looked at the site, and now they are not showing that era car. They sell a whole kit, springs, shocks, etc, tailored to your specific car. Even though they are not showing the kit on their website, it might be worth a call. I have read positive reviews of Jamco in the past in different car magazines.

    Drop a 500 in it. Front lowers : )

    Always made things OK with just an alignment with the extra front weight. The drop was less than 2 inches.

    Come on, it took him long enough to get this​ engine in. I'm sure he's not ready to do another swap anytime soon.

    Impala springs and Bilstein shocks have been good to me for the tore up streets above the salt belt. I like the feel of the setup. Stiff enough to take the edge off but enough give to still test the driver.

    were putting in the impala springs as easy as removing the old springs and installing the impala springs? Just want to make sure I don't have to do anything special when I install them.
    Also, does anyone have any experience with kyb gasajust shocks or monroe SS shocks? I dont have the cash for bilsteins right now but want something stiffer.

    Yep, very straight foward, just gotta index the springs correctly and you're set. Lube the two lower shock mounting bolts a couple days ahead, mine broke and the dremel had to come out. I hear the monroe ss shocks have good reviews. Cant remember if I left the sway bar links together or took them out.

    I love and adore my Monroe SS shocks on my wagon. Some say they are too firm, but I disagree. YMMV. No, you don't have to do anything "special" to swap the springs. Do the rears yourself. You can do it with jack stands and a floor jack in under an hour. It is very easy.

    The fronts, I'll let you know after Spring Break how that goes. lol

    I don't know. I did my Pontiac, acquired an engine for the Cadillac, swapped the engine on my bike twice and am considering purchase of a Custom Cruiser and dropping a 455 in it (like we had when I was a child) and the 500 isn't even in my Cadillac yet.

    A friend who is getting his Hearse back in order was curious about dropping it. I suggested most of the proposed methods in this thread. If anyone has a reference photo of a Brougham on the lower Impala SS springs though, I am sure he would appreciate it.

    Re: lowering advice on my 86 brougham?

    If the roads are smooth where you live, the Monroe SS are a good choice, like Sting says. I used them on my old RMW, but they were bouncy over our rough roads. I now have Bilsteins on my Caprice wagon and they are better (and they should be for the price!).

    A hearse might be heavy for stock SS springs...

    Re: lowering advice on my 86 brougham?

    ^I said the same thing actually and suggested he find some beefier springs. He only wants to go "like two inches lower, at most", so I figure right around where the rear, skirted fender would rest just about level with the rear wheel, given his current ride height.

    Re: lowering advice on my 86 brougham?

    Pics of my setup. Stock Impala springs, Bilsteins up front, Monroes in back and 255/55/17s. Tires are about half inch taller than stock, I think.




    These tires are 215/70/15. A little smaller than stock




    Mine has 215/70s, White one has 225/75s




    I think these were 235/70s but I cant remember. Air shocks in the rear to make the ass sit higher.






    Now I'm just posting random pics

    Stock height and tires

    Thanks for putting up the pics Sam....I really like the way your 84 CDV sits. Thats the look I was going for.....it's subtle, unless you know what you're looking for.

    No problem, hopefully Angry Matt can post some pics of his 2" Impala drop springs. His looks good too.

    Put the car back together today and finally took it to a flat parking lot, just for you Sam. Perfect weather for it. This is with the Eibach springs for the Impala, and 235/75's on the back, 215's on the front. Why don't we have a reference thread for lowering these cars? It seems the subject always pops up.
