How aero is this ?

[daring4]

I guess I'm asking the Aero experts on here if mods will help this car? Should I pull the spoiler off, or does it help air get off the car? I've lowered it 1", full grill opening block and blocked the turn signal pockets with clear tape, removed antenna and wiper blades.

I think your model benefited from much of the development work done on the Trans Am Firebird.
If your engine's okay with the grille-block,then that's a keeper.
The Firebird R&D demonstrated that the openings for the turn-signals don't increase drag.They create pools of dead air that the surrounding flow just skips over.I think it will be same for Fiero.
If you can get a good side photo of the car,you could compare it to the Aerodynamic Streamlining Template Part-C at EcoModder Search above.
Just looking at the photos,I'd say stick with the rear spoiler.Maybe extend the ends down closer to the rear quarter panels so they don't 'leak' so much.
The 'Template' will give you an idea as to whether or not you will want to extend the spoiler straight back a bit ( GOOGLE the Mercedes-Benz 1990 190E 2.5 EVO II ) and see what they did.
There's a ton of ideas to look at with the stickys here at the forum.
The Fiero,being a mid-engine may require special handling with the cooling dept.
It looks like a great project car.I've driven in the Fiero and I wondered about the decision to let it go.Sales figures might clinch that,don't know.
Keep us posted!

Aerohead was the one I hoping to hear from! Cooling should be no prob, rad is at 45 deg to the ground with an airdam and a large opening in front of it. I'll see what I can do to attach the wing to the quarters. As far as dropping the car from the lineup its rumoured to be the 3.4l DOHC designed for the 89 model that killed it, outperformed the 89 vette. I think of it as a porvette! I was thinking the turn signal pockets were acting like little parachutes, can't hurt to leave 'em covered.

That's funny! I've read where,when speed limiters were removed from Camaros and Firebirds,that their top speed could come very close to the Corvette.

The area between the buttresses (over the engine bay) is empty, correct? I don't think that's so good for your Cd. Perhaps an experiment with a Lexan or polycarb sheet that joins the C-pillars would be in order....

It is empty between them but that is the only place engine heat can get out of the engine bay. I see what you mean though turn that area into a sloping back window, right?

Seems the rear wing could be leveled a tad.
Rear wheel skirts and full moons.
Check for a rear "parachute" bumper, just watch engine temps etc.

Good ideas Jason, I just went out and checked under the back end and the rear bumper is not in the way of airflow. It is up higher than the trunk floor so it should be ok.

I would like to get full moons but I have heard of people losing them on the road, that would suck!

Watching temps like a hawk! Its getting warm here so I gotta be carefull!

good luck with this. it is a nice looking fiero.
i almost bought a fiero this winter. it was an 88 GT.
it was in excellent condition and cheap.. it was a tough decision. - i envy your project.

The REAL aluminum racing disks are screwed on and won't fly off. But you have to drill and tap the outer lip of your alloy wheels and not everyone is comfortable with that. I think it would look fantastic on an AeroFiero though.
