are you using the F40 6 speed manual? ive read up on it and heard people say that 1st gear is really short so i figure you would get a lot of wheelspin going around those tight of corners since it allows the motor to rev up so quick. also what did you do to the suspension?

[Zac88GT]

@xTHExWASPx Yes it was the F40 6 spd. 1st gear is really short but with R-compound tires it would just hold the power. 2nd gear is also quite tall and the northstar has a fair amount of torque down low so most of the autocrossing I did I would shift to second right off the start and leave it there for the whole run. Suspension was koni shocks, 350lb/in springs all around and poly bushings.

[xTHExWASPx]

@Zac88GT where did you get the springs from? the stiffest ones i can find are 300lb/in. other than the struts/shocks, springs, and bushings its all factory fiero parts? no sway bar upgrades? because that thing is really flat through the corners and doesnt seem to understeer.

[Zac88GT]

@xTHExWASPx The front springs are 350lb/in West Coast Fieros lowering springs, and the rear struts have been converted to coilovers with 10" 350lb/in QA1 springs. The sway bars are original. The car was setup fairly neutral with the alignment I used: ~9* of caster (I did the 2.25 turn lock to lock F-body steering rack swap so increased effort wasn't an issue) and -1.5* camber in the front and -2.5* camber in the rear.

this is the fiero that pontiac ment to make

HOLY SHIT...THAT'S BAD ASS.

@Zac88GT I recently bought a cadillac deville (2001) and all I really want to do is make it a manual transmission. I found this transmission on craigslist, the getrag f23, is that a good tranny? Also how would I go about doing as in like where the pedal goes, how to install that, or how I would get the stick in the center etc? I have been curious about this for a while

[V8Fiero2M8]

@HEMIH3AD I did something similar to what you're talking about. I got a V8 in a Fiero and I put a cowl (exhaust) scoop on the hood to make the air flow go from under the bottom of the car to exit the hood onto the windshield and roof. If you draw a picture you will see this creates down force onto the front of the car when it moves forward, and it does work at high speed. Not only this works. But the headlights don't pop up.

[Zac88GT]

@HEMIH3AD It would certainly help but I still wouldn't trust a Fiero at high speed. Another way to improve the aerodynamics on the fastbacks is to add an additional rear window that follows the 1/4 windows back, sort of like an older lotus esprit.

[HEMIH3AD]

@Zac88GT what if you install a functional aero front bumper+hood scoop to increase the downforce ? is there definetely no way to build a fiero to be stable at (let´s say) 200mph (like a supercar) ? I mean - the wheelbase itself is only 7cm shorter than the wheelbase of a Corvette C4 which was the basecar for the Sledgehammer Corvette which has been the world´s fastest street legal car (top speed 410kph/close to 255mph)

[Zac88GT]

@HEMIH3AD Short wheelbase+front end lift = unstable at high speeds. I don't know what the theoretical top speed is with the northstar but it's much faster than I would feel comfortable with. The Fiero actually has pretty poor aerodynamics.

[HEMIH3AD]

very dry question: what´s the top speed of this fiero in theory ? I´ve never seen a fiero going over 120mph eventho they seem to be quite well when it comes to the aerodynamics.I mean cmon - there are even street driven VW Golfs with a top speed in the 300kph range (190mph) so a fiero should be able to do the same with ease (with the power to match, ofc).
