Title: Lowered my 87, but she leans
Post by: 86caprirs on October 15, 2006, 05:39:20 PM
She already had the left side lean. I got some new springs.I cut them the same on both sides front and rear. When I was done....she still leans to the left. What gives?????What should I be looking for???

did you reuse the rubber isolators on both sides?

You should have cut less from the left side then ; )

The lean is common in Foxes....

You may be able to cheat it up with spacers or get another spring and try again.

Not fond of cutting springs myself.

What causes this? I have never experienced this myself, but I hear of it all the time.

I am not a fan of cutting either but it sits so high in the front and low in the rear.It has a nice ride though. It got a we bit stiffer but not alot.I will get another spring and do a 3/4 cut instead of a full cut. That should level it out or maybe just cut a 1/4 more out of the pass side.I will see on next say on shop day.

Yeah. What does cause the lean......

Any number of things.  Age.  Compounded manufacturing variances.  Chassis twist. 
My Z-7 requires 1" of spacers in the pass rear to make it sit level.

What's wrong with cutting springs?  It's cheap, firms up the ride, and is "adjustable." ;)  Plus, if you get a lean, it's easy to fix. :D

This is a local guy here that does a lot of Fox body stuff.  One of his "things" is lowering.  He can get it this low without riding the bumpstops and riding like a tank.  He uses stock V8 springs (cut) and makes adjustments to the spindles, shock mounts, and uses aftermarket struts/shocks to get the ride dialed in properly.  All with no tire rub.

I think I'm gonna try to get my '84 this low in a few weeks, just to see if I like it.  I can always put it back.

Wow. That stang is low. I never went to that extreme.I have about and inch or less clearance between the top of the tire and the top of the wheel lip. I will get pics later. It has a nice lowered look with a little rake to it.

I was attacted by my daughters cat and have been at the hospital 4 times for intervienis(sp). It seems better today but the swelling in the fingers is killing me.

When you cut springs, you will almost always change the temper of the spring material, which will have an impact on the spring rate and strength of the metal.  I've seen way too many cars lowered by cutting the springs which ended in severe handling problems, and even accidents from loss of control.  Yeah, it's cheap, but is it worth the risk?  Not to me.  Cutting springs is a very bad idea.

thats pretty f'n low with spring and shock mods. does he fix the geometry too?

Well I have to say that the ride is a little stiffer,not much, but it handles great. It does not feel like I am trying to drive 72 Lincoln Continental.It has a nice responce to steering input.

I don't understand how you change the "temper" of the spring.I cut the spring on a water chop saw for metal. The spring did not even change temp.I guess I could change the spring rate but the spring was the same size thickness at the bottom of the spring to the top.

Temper?  lol.  There isn't sufficient heat to turn the spring brittle.  So any time you want to change your car's ride height, you need to buy a new $200 set of springs?  Please.

Yes the geometry is changed significantly.  Before I speak out of my ass about the specifics, I'll just tell you what I do know.  It uses '94-95 SN95 spindles, caster/camber plates with additional adjustment for caster, and he does not raise the rack for bump steer - which I thought was odd.  But I've driven the car, it is fine.  No woogedy wheel over speed bumps and such.  Not sure on the rear yet.

It's probably not the hot setup for autocrossing or tire wear but it looks cool.  Who gives a shiznit how many Gs it can pull...

I had an issue with the rears, but it was because of the way I rotated the springs when I reinstalled them (tails were pointed the wrong way - doh!). Of course I have the adjustable height lower control arms anyway - lol.

I just put a before and after pic in my domain site.I don't know why my pics are dark when it is light out.

"Tempering" a helical spring has no effect on its spring rate. It will change the yield strength and at what point the spring will "set".

That's what coilovers are for. :grinno:

So he would spend the money on hardware to assist a lowered vehicle, but not on the springs themselves? Not that I'm against cutting springs, even planned on doing it myself, but I figured if I got to spend the money on the other parts I may as well cough up the dough on the springs as well.

BTW, the Mustang looks good. Like the wheels.

Spring rate isnt just determined by thickness, but by the amount of material in a given distance. By reducing the distance, it effectivly alters the spring rate.

Yeah...cutting springs is awesome, since everyone here drag races, and drives straight only! No turns for me!

I don't drag race mine because I daily drive her.

It lowers the car and stiffens the spring rate.  Yes, that's what everyone does for drag racing their Fox cars.

Some of you guys are.... funny.
