Fiberglass body parts, how far to go with my 6 conversion Options

[billd]

I'm moving the oil cooler on the front of my 914-6 conversion and started a dangerous train of thought that is likely to keep my car on jack stands for months longer and empty my wallet (even emptier than it already is).

Rather than cut a notch in my existing steel bumper and valance I thought, why not buy a fiberglass 916 bumper (or a 914GT bumper and valence). That would save a few pounds.

While I'm at it, I could also get some fiberglass flares, fiberglass front and rear deck lids, and a fiberglass rear bumper.

I hope you folks can help me decide how far to go by answering a few questions:

1. How much weight is saved by replacing the steel bumpers with fiberglass?

2. If I go for flares, do you recommend 7 front/9 rear or 9 front/11 rear?

3. How much more weight can be saved by going to fiberglass deck lids, etc?

4. I assume that I give up all of the protection of the steel bumpers if I go FG. Right?

For reference, I'm buildling a 3.2L short stroke engine for this car with twin-plug heads, 9.5:1 compression, and Megasquirt fuel injection. It should be over 250hp.

remember, I'm talking about a race car...
so on a street car I would start with all of the floor board insulation/tar

next take out the insulation in the engine bay

then the rubbber insulation matt behind the seat back pad

then the headlights, fog lights, horns, headlight motors, fresh air ventilation, rear heat system and heat exchangers, door glass, rear glass, door regulators, dash, interior....

heck I pulled the full wiring harness and saved about 20lbs right there.
(rewired only what was necessary with aircraft grade wiring that is lighter weight)

like I said, I'm talking about racing.
a lot of things would be nice to have still if it was a street car
still you can take all of the insulation and tar out of a street car and save about 75lbs, with the only trade off being road noise.
