I think the main thing that makes a fiero stable at high speed is a lowered car with better shocks and really good tires .The pop up lights have either got to go or tape them up before you try a run .And a vent to get the pressure out behind the rad .Other than that , the natural wedge shape works pretty good .I wont bore everyone with my mods , you can look them up if you want .I had my car doing 130 on a bumpy road and it was rock solid .4500 in 5 th and still climbing fast . I would love to find out how fast it will go , but there is no place around here to do it .Someday I would like to take it to a Texas mile type event but I dont know if that will ever happen .

I would abandon any goals of very high top speed, unless you are going to redesign the suspension I would not want to go that fast in any Fiero. I topped mine out once and I have all polyurethane bushings, all new ball joints and tie rods, new KYB shocks, shop alignment, newish tires, and it does not feel good up there compared to a lot of other cars, I think my minivan is more stable at high speed than the Fiero.

Instead I would focus on neck snapping acceleration since the Fiero has the weight over the rear and can really put some power down

not yet im afraid...sorry.

I'll ask for some more tomorrow.

In the meantime, what do u guys think of Blue Fiero's? I always thought they looked kinda tacky (no offense to those with blue fieros) but i found a really nice blue...its 3m matte metallic blue. Might look good on a Fiero??

I like the really, really, dark royal blue color on the Fiero and just about any car...

Yeah some ppl have done really nice things with blue on the Fiero. like that blue chop top from v8 archie looks cool, but again, i think the matte looks cooler (to me anyway) but noone has done it, so i cant say for sure. Ive seen a few matte black/red Fieros. but thats it. So hard to imagine what your car will look like with original idea's and noone has tried them, u dont wanna waste your money if it fails. bah.

Airflow management is the key to high speed stability.

The lift coefficient a car makes changes with the 4th power of pitch attitude. Longer wheelbases make pitch attitude easier to control, as a given suspension movement results in a smaller angular change of pitch attitude.

That doesn't mean it can't be done on a short wheelbase car... it just means that you have to have your aero very well sorted. Air under the car is the enemy of high speed stability.

no...ive been trying to get ahold of the mechanic. He said a week ago that he should be able to start the engine last wed. So im trying to see if that happened. He has no cell reception at his shop. So i have to wait till he comes to the city for updates. Sorry guys!

I don't see a problem with having a lofty goal, as long as you know that it's going to get pricey with diminishing returns. I will add though, before you start pumping out the power you should start by making sure you've taken care of all the safety related upgrades (such as brakes, suspension, tires, roll cage?)
