New to the forum, can't believe how much valuable information I've gleaned from it. I'm building a 72 Chevelle coupe rust-free Arizona car. The car will be driven by my son. Have a fresh 327 smallblock from a previous project. (Car came without a motor). TH400. 12bolt, Eaton posi. Have had the lower trailing arms boxed, front and rear swaybar ready to bolt up, new rubber bushings on trailing arms and a-arms. Wanting to lower the car about 2" all the way around, under the impression that drop spindles are the way to go. Car is going to be a cruiser, no racing, no track days. I may install big block and go closer to Pro Touring when the son is done with it. I know at least springs will need to be changed, however want to build with that in mind. Thinking about the following:
CPP front and rear disc brake kit w/2" drop spindles.
Undecided about wheels, may go 17"s may go for something more from my generations like 15" 200S Americans so will stay with 'small' 12-13 inch brakes.
Question: Is drop spindles the way to go to drop? What about springs? Thought I would use springs to drop rear. Seen other posts with talk about 750#front, 150#rears. Seems a bit stiff for a cruiser. Anyone want to throw in? Please?

Welcome :beers:

The 2" drop spindle kit from CPP uses 10" S10/G-body brakes, and a cast steering arm (in a less than optimal position). I would avoid that kit like the plague :eek:

You'd be better off with a stock spindle, stock 11" brakes, and 2" drop springs. Some 12, and all 13" brakes will interfere with 15" wheels. 13" usually requires a 17" wheel, and many 12" require 16" wheels.

What size sway-bars did you intend to run?

With springs and sway-bars, there are basically 2 ways to get the job done - soft springs/big bars or stiff springs/small bars.

I'm going through the same thing. I am having a heck of a time finding any springs that offer more than 1.5" drop. What does everyone else here use??? The only brands i can find are Hotchkis and Eibach.

Derek, thanks for the reply. I have noted your other posts and respect your opinion. Let me add some wood to the fire. The front sway bar is the 'stock' one, not certain how many diameters they had. Two, the rear is one I bought from OPGI with the box kit for the lower trailing arms. I would give you measurements, but they are at the powder coater, will pick up tomorrow. I will post diameters tomorrow evening. Please stay tuned.
What is the optimal set-up? I would be willing to 'undo' (read through away some of the plans I had) to make sure this thing goes together right. I think the boxed lower arms are good. I do want to stay with rubber bushings, I don't feel like I'm after the added performance of uruthane and don't want to create too much of a beast.
So, in the rear it looks like a need a pair of lowered springs. The front, Stock lowers. SPC uppers? Tall ball joints? Spring suggestion? Adjusters? Where is the best place to get the stock components you suggest? Spindles, brake setup. Ebay? Sorry so many questions, just trying to find my way.... Thanks!!!!

Afco, BlackMagic, and others selll 9.5" springs that yu use an adjuster with.. you can go as low as you want... Cut and past this link and you'll get all the info you want on springs.

Chaos, Derek, the sway bars measure .93 inch front, .99 rear. (1 inch). I have read the link that Chaos supplied. Looks like 5x9.5 for front with adjusters and 5.5X11 for rear are the hot setup. Looks like the softest rates I can go are 150 rear, 750 front, which still seems stiff, especially compared to the stock f41 rates. With this setup, it looks like stock spindles, 11" disks are the way to go, if i want to have the option to fit 15" wheels. Still not sure the hot setup for rear disks. I believe Derek provided a link for DYI discs by modifying the stock front drum spindles in another thread, is this a good path? Will the alignment geometry be O.K. with lowering the front with the adjusters? There are so many variables and options, my head is spinning. I believe I've seen claims that certain big brake setups conflict with a-arms... Arghhh. I've almost lowered my expectation from optimal, to just not throwing money away on parts that will not interoperate... At what point or why do the SPC uppers with the tall balljoints come into play? Can I use the stock modified drum spindle with them? Thanks guys, I appreciate the help. Between springs, and brakes for all four wheels, I'm about to spend some major bucks.... Anyone else is welcome to throw in too...
