Re: fiberglass front bumper cover 89 GTA ??

Thanks , I am looking to shed weight out of my car . My factory bumper cover is still nice but for racing I would prefer a fiberglass piece . I dont know if I am going to have to get a special mold made or if someone makes one already . I see alot of one piece front ends but that is not really what I would like . Thanks

as far as I know noone makes a fiberglass bumper cover unless you want to buy a knight rider kitt style one, I know some companies make those out of fiberglass, but I think they are quite pricey though

Re: fiberglass front bumper cover 89 GTA ??

Yeah I did not think anyone does. I have vfn and glasstek local to me. I am hoping that if I supply a front bumper cover they might be willing to make a mold for me . I would also like a fiberglass stock hood, but none that i see accept the factory hood vents into them . My car needs to retain the factory appearance due to my own preference and just not alot of nice pieces seem to be available for my needs. If i want a 4" cowl or 4th gen WS6 hood not a problem but a nice stock light weight factory appearing hood is an issue.

I know you said why you want a glass front bumper cover, but I have to tell you I sure never want one. Glass does not hold up near as good a urathane and like to crack. I don't think is all that much lighter if any really.

I can agree on a lightweight fiberglass TA/GTA hood. I want one, no one makes one. I suppose a good body man could probably modify a fiberglass firebird hood to accept the vent inserts and such but then you are out of luck if they do crappy work.

As for a fiberglass front bumper why would you need one? It won't be any lighter than a stock one, and it will certainly be much less damage resistant. The stock one gives a little and moves so if something does it it, it will flex. Not seeing a real reason to have it.

Re: fiberglass front bumper cover 89 GTA ??

I want it to be rigid because at 170 mph the front starts to deform and does not keep the aerodynamics . If the cover does not distort it will travel through the air cleaner and take less horsepower to mph. For a factory car yes fiberglass would not be ideal.

it doesn't deform that much. Polly uses a stock/modified cover on his 253mph TransAm.

With the impact bar behind it, even when the cover compresses it hits the impact bar with before the cover deforms much.

Re: fiberglass front bumper cover 89 GTA ??

It distorts pretty good. I have pictures of it deforming on the top end of the track. I have enough power to overcome the drag if I was a top speed car, but with only 1320 ft a little flex is a significant drag on the car in a short distance. Also the angle of the nose on my car would be upward as the car is trying to lift the front up. Polly I am sure rides at a different angle , low and level creating less distortion of the front.
