I bought a set of 250,300,350, 400 and 450 for testing and settled on the 450 in the back and 400 in the front.
I bought all sets in 12 inch lengths but later had to get another set at 450 pounds in the 10 inch length for the back. The 12 inch didn't allow me to lower the car enogh.
I set my ride height in the back with a level on the 1/2 shafts.

I know that a few have done this mod, and since I will be pulling the body off I thought this would be a good time to approach this project. I did a search but all I came up with was info on the front. Can any
one point me in the right direction for the mounts I will need for the rears??
Also has any one ever made their own control arms for the front???
Thanks in advance,

Hello Norval
I sent you an e-mail about the possibility if you want to sell some of your springs
My coil overs are behind the rear end, straight up and down
take care
Tom
hope to see you this coming summer at a cruise night

Here are a few pictures of my rear coilover mounts. They are welded to the trailing arm. They also place the shock in a straight up and down position. I used 1/8th material, boxed it in and welded a threaded mounting boss to the bottom'
Everything falls inside the 18 inch rim so no chance of bottoming on the ground. they are also no lower then the strut rod mounts.

That is not yellow overspray on my 1/2 shafts. I purposely spray like that so when I remove and replace anything it goes back on exactly as it came off. Alot of removable parts are oversprayed over the black powdercoating so I get it back in the same orientation as it came off.

As for literal...if you want 1150# springs, hypercoils have them.

For an upper mount I put it in the same location as the stock mount. I cut the stock mount off, plated the frame both on the bottom and side and then welded a solid billet mount in the same location.
I ran a 140 pound leaf spring that mounts to the back of the trailing arm. With the coilover and the spring mounting in FRONT of the axle you require alot more spring pressure. I tried everything and kept bottoming the suspension. The 450 pound spring ride about like 140 pound rear spring

Norval, is that your emergency brake caliper? was it you who was thinking of mounting an emergency brake & small emergency brake rotor on the front of the differential? or was that TT?
What calipers and rotors are you running? In the last pic the calipers look stock.
Your coilovers didn't hit the battery & storage boxes?

TT is losing his edge, i think DB caused him to have a small stroke.

No my coilovers do NOT touch the battery boxes. No paint on the boxes has ever been scratch. They clear under the worst conditions by about 1/4 inch

My son puts the parts together to make a hydraulic emergency brake. It consists of 2 light weight rotors with 2 live pistons, 4 brake pads with free replacements in the future, 2 master cylinders, one for each rotor, 2 flex lines and an assortment of banjo bolts and washers, he just grabs a handfull and throws them in the box.
You have to make aluminum spacer to spread the caliper for our larger rotors, a mount for the trailing arm , a spur for the parking brake, mount the master cylinder and slightly space the back of the brake cover up at the back for clearance.
It actually comes together quit nicely and works. Who can say that about the stock setup???

thanks Norval, The trailing arm is a lever and has much more mechanical advantage at the convenient coilover mounting position in front of the axle. The leaf acts upon the very end of the arm behind the axle.
TT is losing his edge, i think DB caused him to have a small stroke.

You just said you need a 600# spring to do the same as a 420# fiberglass one. There was no mentioning of spring location so in that respect alone the whole statement was moot. Now, i know you're going to say I'm being **** and what not..

And there is no way to mount the springs behind the rear wheels,huh?

No booster, no leaf spring. I just said the leaf spring that mounts to the back of the trailing arm was 140 pound per inch spring. With the coilovers mounted in front of the axle I required a 450 pound spring because of the mechanical effect.
I just want to save someone money and not buy all the sets i did for testing. Springs here run $172 per set and I bought 6 sets or about $1000 worth just to find 2 sets that I could use.

I can see from the amount of mods on your car that you have much more ability than I do at this time. I also believe you probably learned these skills by just jumping in and doing it, and I guess that is what I will have to do also. I have a lot of questions but the channels of communication become muddy here from time to time.
SO I think I will look into someway, if poss, to mount the shock and spring to the rear of the axle.
Thank you for your time and patience again!
