I have recently bought my first fiero it is a very well done Ferrari f355 replica.

At some point someone removed the front springs and shocks and put a coil over in the original shock location.

The car has a terrible shake in the wheel when cruising and I suspect this is the culprit

Just seems wrong to me.

With all the force of the cars weight on the rear leg of the lowe a arm common sense says it will be prying up on the front leg of the a arm instead of dividing the forces between both legs.

Also the shock mount on the sub frame does not look strong enough to handle all the forces of the front suspension.

Could someone please give me some advice here I'm concerned that this set up is wrong and possibly unsafe.

Any advice is greatly appreciated.

That is probably your problem, and I do believe you are right about it being unsafe, I would find a set of stock springs and get a set of Rodney's lowering ball joints and some new upper ball joints too. New rubber for the arms would be a good idea while you are at it, but may not be necessary depending on condition of the rubber. Welcome to the forum.

I'm deep in the cornfields of Iowa so everything is mail order out here

Do you know of a source for the lowering ball joints?

I was going to say Rodney Dickman at http://rodneydickman.com but he does not have them listed anymore for the pre 88's.

Rodney has been a great resource for the Fiero community but I know he was looking to wind up/sell his parts business a while ago so that may be why.
You could try contacting him to see if he has any hidden away or knows of another supplier.

That does not look safe at all. The control arms are made of sheet metal. The forces being exerted by the coilovers are going to twist the control arm back and forth. And now, the entire weight of the front end is resting on those sheet metal brackets. Not good!

If you're looking for a project, you could make your front suspension ride height adjustable, using the stock mounting points. I did that on my '87 Fiero. I removed the upper spring perches (the metal cones with the rubber bump stops on them), and replaced them with adjustable spring perches. The shocks were left in the stock location. If you're interested in building something like that, there is some info in my build thread.

The front suspension build starts about halfway down the page.

I just went to Rodney Dickman's site and it shows both the 1" and 1/2" lowering BJs.......Check with him- he probably still sells them.

...and none of us get paid a commission from Rodney either. We're all just satisfied customers.

Update

This is the bolt I removed from the front a arm rear lower bushing.

As you can see it has been under excessive stress

The bushing came out in chunks

The front bushing and bolt showed minimal wear

By the looks of everything I'm guessing it's only been like this for maybe ten thousand miles

One good pot hole
and this bolt would have likely broke
Putting me in the ditch

If I was lucky.

Yikes! That is really scary and bad....That is not the right location for a coil-over system...It can handle shock duties but not the spring forces......

Seeing disasters like this is why I prefer to avoid modified used cars... bone stock is my preference.

A lot of the time you don't really know what you are buying, even when you know all the main trouble spots, there's a lot that's easy to miss, and this is his first Fiero.
Still, he's found it and hopefully will be able to save yet another one from the bodge it school of repair!

Anything I might say is probably worth what you paid for it, so treat it accordingly!
