i just got done puttin my front suspension back together.i have 77 nave spindles on my metric car.everything went together fine but i use regular 9'' racing springs and now they seem to have some "slack" in them.is this a normal thing?i think when i put the weight of the car on it the slack will disapear.what do you think?

I don't understand what you mean by "slack".

marple, Your car will sit at the same ride height as before the change.......the thing that will be different is the upper A-frame angle when finshed setting it all on the ground. This will change your front roll center location.

as you bolted on the new parts, because the spindle is "taller".......longer from top ball joint to bottom ball joint........as the front susrension hangs it allows the lower A-frame to hang farther down......this is why the spring has 'SLACK" as you called it.........

hope that helps you understand what changed.

Marple, I did this myself with cutlass spindles from a 77. I to experienced the slack. My spring spacers ended up only being about an inch tall. This give me a decent ride height, definetly could have been lower but it was ok. However, if I jack the car by the frame or crossmember the spring unsettle and "pop"whenever you set it back down. Just one of the drawbacks I guess. Tell me if you will, how did you get enough neg canber on the right hand side. I figured it out, I just wanna see how you did, I will offer mine to you later. Thanks.

as far as the camber on the right.i'm gonna cross my fingers and hope there is enogh room for shims in the uppers.if not i might grind some off the inside of the shaft.

Don't you have to run a shim on top of a 9" front spring? What kind of suspension travel do you have? I might not be clear on what you are doing, but I have to run a shim on mine or I only have about an inch of travel

i had those hidden adjusters in there when i first built the car in 2000.when the local track champion felt sorry for me and came to set my car up he MADE me take those out.this got the car a lot lower and i dunno if it was his setup or that lil adjustment but whatever it was, it made the car handle 10x better.

but i got a plan for keeping the springs from "popping" like redneck said

Ok marple heres what you are gonna need to know. It aint gonna work. Pretty simple huh? You will end up having to add longer bolts and then they will hit the manifolds. Take you pass side upper a arm off. Remove the ball joint and weld up the 4 holes where it was bolted in. If you have access to a plasma it will come in handy here, if not use a grinding stone on a die grindr or drill. "Oval" the ball joint hole towards the shaft, you can keep putting the ball joint in to check and make sure you can go further. Do this until it hits the angled part of the arm. Mark the new mounting hole locations and drill them. You should be able to get 3/8" to 1/2" extra here. If you want more(which you shouldn't but I did it anyway to keep the number of shims down) remove the lower a arm. Drill or cut new holes as far outboard as possible in the frame. On the front you will get about 1/2", on the rear go ahead and move it all the way out, it will be about 1". This will help build in some caster. You can use a washer but I choose to use some 1/8 or 3/16 plate to go over the area. Make sure that you use a drill here, no slack allowed. I welded it all up and then added a little grease and dirt to age it. The bolt that use to go in the front will now need to go to the rear, I used a motor mount bolt for the front, they will be a little short if you use plate to reinforce. Good luck, any more info post here or email me.

thanks redneck .i was tryin to avaoid that but i guess i guess i gotta do it.
to avoid the popping without using a spacer think about what you do in the rear to keep the springs in there seats.thats right cut an appropriate length of chain and weld to the lower control arm,then to the frame.wala no popping,and no need to give up ride height.
