Hi guys!

I just purchased brand new KYB shocks/struts and Eibach springs to lower my 1986 Se FIERO V6.

1st question: After installation, do I have to make a new alignement?

2nd question: If yes, can I use these factory specs?

FRONT:
Camber: +0.5
Caster: +5.0
Toe: +0.15

REAR:
Camber: -1.0
Toe: +0.15

Car has 16" rims with 225/50 on it!

Thanks a lot for your help
Regards from France!

After lowering the caster will be off. Not sure if it will have a big impact though...
A way to correct this: replace the single thick original washers on the upper control arm bolt with thinner ones, adding more at the front and less at the rear, like just visible in this pic:


This will move the upper arm slightly forward, compensating caster change by the lowering.

Even here in europe the alignmentshop should have the specs for the Fiero in their software. Make friends by using WD40 on bolts and threads that may need adjusting, before you drop the Fiero off Good luck!

Some workshops have the fiero listed in their software and some dont - However if you go to a good bodyshop they should be able to set up the fiero using 4 wheel laser alignment to any specification.

Thanks all for yoour help

OK for rear Toe = 0°, but what about Front Toe?
I had Front Toe specs should be +0.15°.

Is that right or should it also be 0.0°?

Thanks again

A slight bit of toe out in the front, will make your car dive into the corners a little better.

So you recommend keeping the +0.15deg for the front?
Thanks

Toe OUT on the front? Shouldn't it be toe in for a RWD car?
