5660 Springs 9/25/2021

This great stuff. But...............one good piece of info that is missing for me is front end weight because all of our stuff has T6 turbos and related stuff up front, but no A/C or heater boxes.

I'm very curious what your front end weights are. Are the turbo and intercooler/piping equivalent to having an A/C compressor and related heater box items?

Added pics and some more info for weight reference.
I would love to throw my car on scales as it is now and when "I finish it".

My stock F41 fronts (left) and 5660's (right)

It should work fine but actual ride height is a crapshoot. The 5660's are stiffer and shorter so if you have a factory v6 car and swapped a V8 into it the OEM springs have probably sagged over the years and the car rides lower than it did new. If you don't put tall lower ball joints in it will probably raise the car if you put stock spindles on. (plus there is literally no reason to not put the tall lower ball joints in)

I'm really interested in what my ride height will be. My car was a V6 auto car with sagged springs, but it sits higher now with an iron head 350 and T5 trans. I'm expecting it will sit even higher with the Moog springs.

Think I might cut a half coil off before even trying them. And if that's wrong I have a set of low mileage springs out of a Grand National I can throw in.

My car has a very serious lean towards the driver's side that I've gotta try to work out of it soon.

Well, its been over a month and my cars still sitting on jackstands in my garage. My own doing. I wound up having my lower control arm sandblasted due to the way the SEM Hot Rod black dried. Two coats of primer, two coats of paint. Too many coats and a pain to sand. Blasting was so much easier. I also pressed in a new Moog ball joint. Now its hanging on my rack right next to the coil spring while Im still waiting for the free quart of paint coming from SEM. I dont think the customer service guy is screwing me. He said they were making a fresh batch and it would be shipped soon. We'll see.

This front suspension/spring/tire and wheel size issue is still going to hold me up. Lots of answers on this forum. Tons of info. To be honest, its lack of experience on my part. Theres a lot that I can do on my own as you can see when you look at both of my projects but this spring crap has held me up.
The spindles, the different springs. Im not dumb but I really dont understand how this comes together.
This picture was taken last month. Its how my car is sitting right now with 2" dropped spindles and 15.50" tall springs that might be factory. Its up a little in the front but Im thinking it might drop a little once things settle. It was pretty low before I took everything apart. The tires are 205 60 15s. Theyre 24.6" tall.

Many suggestions for the Moog 5660 springs. I think theyre 13.25" tall. Thats 2" shorter than the springs in the car now. If the stock spindles are going back in wont that basically put me at the same ride height that it is with the stock springs and the 2" dropped spindles ? Wont I be in the same situation that Im in now ? And if I switched to taller ball joints wont it be even lower ?

This whole thing is holding me up and basically its just because I want to run a nicer set of tires and rims. SMH

Im running out of things to do. Yesterday I cut out the Ozite for the cargo area. This morning I got a call from New England Chrome Plating. The back glass handle is done and being shipped today. It might be here tomorrow or Friday. Im so close to being on the road. I want/need this car to be finished. At this point I cant even move it because I took the left spring, spindle and control arm down. This is VERY frustrating.

5664s, 1/2" taller lower BJs, and 2" drop spindles are the cat's posterior. Plus, the ZQ8 bump stops. The 1/2" taller upper BJs are a nice addition too.

What wheel size & back spacing are you using w/that set-up? I have wondered if the additional ~1/2" from a tall lower BJ in addition to 2" drop spindles would cause the TRE to contact the wheel lip depending on the numbers/dimensions of the wheel used.

I like the sleeper look of your wagon! Those fronts are shorter than stock tires, so that will lower it too. For comparison, I've got uncut 5660's with tall lower ball joints and stock tires, I'm at just under 7 1/2" to the frame right behind the front tire.

But what did you do for tires and rims ?

Went back and looked at my post from when I installed 5660's in my Cutlass (305 sbc, auto., A/C, aluminum hood and bumper supports, 225/50-17 tires, 25.9" tall, on 17" x 8" 0 offset rims, so 4-1/2" backspacing) they raised the front end 1/2" over the original springs. Took them back out and cut off 1/2 coil. I have since installed +1/2" taller UBJ's and LBJ's with Summit upper control arms. The only rubbing I have is the rear of the drivers side wheelwell, and the Stabilizer bar at full lock.

235/60/15 on 15x7 with 4 1/2” backspace.

Im so confused. Stock springs. 2" dropped spindles. The previous owner switched to the 205 60s because the larger tires rubber through the inners on both sides. How the heck can a larger tire work on your car and rub on mine ? It cant be just the ball joints. The 5660 springs are 2+ inches shorter that whats in the car now.
