What are the best non-invasive weight-cutting techniques for a 911?

[p7guru]

If you were going to modify your 911, and try and cut some weight, what would you do if you didn't want to ruin the car's enjoyability?

1. Maybe a aftermarket exhaust? Especially on the 964 it looks like the factory unit is heavy.

2. Delete the rear seats?

3. Race battery

4. Tools, etc.

5. Aluminum rear lid (delete 964 tail).

What are some good ideas?

Remove sound proofing.....go with glass fenders, hoods and bumpers, lose the AC, stereo, carpets.....

[byfdinky]

Delete Air Conditioning!

[Oh Haha]

What is your goal? Track days or just spirited driving adventures?

All items posted already will reduce weight.

Some more:

Race/lightweight front seats, replace the sunroof(if equipped) with a panel, lighter wheels.

What is involved in deleting the ac?

[Joe Bob]

A couple of wrenchs and cutters.....time.....

[James Brown]

Just remove everything you don't need to win.

Look at what the factory did with the Euro 964 RS, then look at the Cup cars, and find a place in between that you can live with.

A healthy diet and exercise. You can even carry the weight savings around to use in other vehicles :-)

Unless you're doing burnouts to the rims. Then fill with hydrogen.

Huh? how so?

[stormmaster]

Loosen and remove the nut just behind the steering wheel....keep it as far away from the car as possible....good for a couple hundred pounds in most cases

electric seats are heavy

the windshield washer bottle could carry 2 gallons

They scratch easy, as in whenever you try to clean them.

Even at their best they are much cloudier than real glass.

If you use them for the side windows, you will need to make custom window raisers to get them to go up and down.

The rear Lexan is too thin for the gasket so the fit is poor, and aerodynamics are not as good I suspect. I would like a flush mount rear screen.

They are flexy and bulge with wind pressure.

I was going to have some Lexan side windows but I would have to fab up some window raisers for them in my fiberglass doors and then I do not know how well they fit in the frames meant for glass. I left the paper on during the project and it took longer than expected. The paper glue bonded to the Lexan and was not able to be taken off so they went to the scrap pile.

I am running Lexan for the rear quarter, rear, and front quarter windows. No side windows and a glass windscreen. I would not want to use Lexan for the front screen for the poor visibility. I would like some side windows sometimes, though.

For a track car, they are a good way to take off weight up high.

For someone looking for weight reduction on a street car, no. Swap out the heavy seats, bumpers, AC, radio, battery, rear seats, etc.

Driver weight is the best place to loose it.
