I know in 88 the GT's got reworked suspension thats suposedly better. I have 2 questions.

1. Did all 88 fieros get this upgrade or just the GT's? So would that mean all 4 cyliudners, SE's, and formulas, or just the GT's?
2. Is it really worth it to bother? If yes, how easy is it to swap into an older car or is it impossible? (Thoguh i think nothing is!)

Also just for fun,
Whats the best brake upgrade for any year fieros? I know some are out there, anyone with personal experiance?

Thanks!

I asked the same question LOL All 88s have the same suspension except for four cylinder coupes do no have the sway bar

Yes... all 88s. Yes it was much improved. Yes you can swap, the rear is doable, the front is another story. Most people don't.

Here is a list of the revisions...

1988 Fiero New Engineering Highlights:

- Completely redesigned indepenent front and rear suspension systems
- Revised four-wheel disc brake system (vented)

Front Suspension:

Elimination of the steering damper assembly
Relocation of shock (inside spring)
30% shorter spindle length (90 to 64mm)
30% shorter scrub radius (49 to 35mm)
20% reduction in king pin angle (7 degrees to 6 degrees)
20% longer upper control arm length (177 to 214.2mm)
25% longer lower control arm length (280 to 350mm)
Larger stabilizer bar (22 to 28mm)
12% shorter turning radius (11.4 to 10.2m)

Rear Suspension:

Redesigned chassis cradle for suspension attachments
Cradle is hardmounted
New tri-link design allowing for specific tuning of each component
Increased rearward rear wheel motion with jounce for reduced impact harshness
Lower spring rates (44N/mm to 25N/mm)
Inclusion of 22mm stabilizer bar with the WS6 suspension package

Here's a site about do-it-yourself alignment that has front and rear pictures of both suspension types.

Some people think that the coupes got softer springs, while others say that all the springs had the same rate but were different lengths to account for differences in ride height. Personally I think the coupes got softer springs.

In the rear, definately. Swapping in an 88 rear cradle and suspension has always been received with accolades, even by those who have tuned their early model cars for racing. Supposedly, this is an easy swap for the shadetree mechanic. If you ever come across a spare 88 rear suspension, you'll kick yourself later if you don't grab it up.

In the front, probably not worth it. The front suspension on the 88 is definately better, but the early model front suspension isn't really bad as far as sports cars go. There are plenty of things you can do with the early front suspension to improve it's performance dramatically. Not to mention that all the "rare and expensive" parts for the 88 fieros seem to be in the front suspension. And so far everyone that I've ever heard about swapping in the 88 front has had to do tons of work to get it to fit, with very little benefit to show for it.

Thanks for the replies guys!
