Totally newb question im sure and i think i know but i wanted to confirm before i buy body parts, whats the difference between aero and non aero. The pointed nose fieros are non aero and the curved front nose is aero im guessing? or is it between fastbacks and notchbacks?
Also is there any difference between years on the doors?

The doors are interchangable. The nose is also interchangable. The issue is the ground effects. The Aero nose ties into the GT ground effects. It wouldn't look quite right on the car without ground effects.

Hope this helps.

There are differences under the noses..Not just a swao bolt on.

As mentioned, all doors are interchangeable.

There are essentially three different fascia configurations on Fieros.

The first is the bumper pad bodywork.


Next is the "aero" coupe that replaced the bumper pads in the later years


And then there is the aero that's on the Indys, GTs (except 85), and aero SEs


Each one mounts slightly different. For each model, whichever you decide to switch to you will need the inner fender liners, and as Old Lar has said under each nose they have a piece that runs under the bumper that helps with directing air for cooling, so you'll have to have that as well. Depending on what you're going with, you may also need the egg crate absorber. If you're going to a aero fascia you should be fine with any of them, but if I remember right the GT's is slightly larger than the other noses (could be the rear fascia. can't quite remember...).

Aero is anything with the lower ground effects throughout, starting with the '84 Indy. There are two types of Aero panels too - square molding and round molding - the square stuff is normally found on notchback Aeros, round on fastback Aeros - doublecheck your parts beforehand to make sure you have the right thing though. The doors are all structurally identical, just with minor differences again with the moldings and extra holes for ground effects. The bumpers and skirts are all interchangeable too, just remember to take all the support hardware that goes with. I think the front wheel wells go with the front bumper, and be aware that the rear bumpers change between fastback and notchback.

Alright so i have an aero SE then. The previous owner hit a snow bank and the door is all banged up, figure id swap the outer part of the door so my car looks normal again. Whats a decent price for the outer door skin? The one i was looking at is 120 shipped and already silver.

The 85GT's also had the aero nose

Nice this thread is what I have had on my mind for awhile. I have an 88 Formula (like the white formula pictured earlier), and I want to convert it to the notchback GT (85?) look. I bought an aero GT nose (like the red one posted a little farther up).

Can any of you fiero gurus tell me what I will need for the conversion. When I bought the new nose I guess I didn't notice the difference in the side skirts between the formula and GT's. Has anybody just swapped the front fascia without the sideskirts? or would that be an eyesore?

If anyone knows of a thread that a nose conversion is covered in, or just wants to give me some instructions. I would most definitely appreciate it.

I believe that this is correct for the most part, isn't the lower trim piece different on the aero door than a non-aero door?

quote Originally posted by Fiero84Freak:There are essentially three different fascia configurations on Fieros.

This is correct as far as fascias but there are actually 4 body configurations. The original (bumper pad, Mark Corbin's Fiero Spotter's Guide calls this "Standard I") coupe, the later coupe (MC/FSG calls this "Standard II"), the aero coupe (MC/FSG calls this "Aero Notchback), and the '86 thru '88 GT (MC/FSG calls this "Aero Fastback").

quote Originally posted by Fiero84Freak:Next is the "aero" coupe that replaced the bumper pads in the later years

I disagree with this, the Formula is a coupe with a wing, not an aero coupe. The aero coupe is the Indy Pace Car, the '85GT, and the '86 and '87 SE.

I disagree, the aero is only the 86GT, 87GT, and 88GT

Yeah, there is a slight difference with '84 doors, but they'll still work. You just have to do a bit more work.

Notice that I put quotes around "aero" in my original post when referring to the '87 coupe and '88 coupe/formula body style. People still refer to those as "aero", just not THE aero that we typically refer that word to.

I was thinking of fastback for some reason when I mentioned GTs, so in that thinking left out '85 GTs in the aero. Why do they have to be so different?
