Actually, early Porsche 911 CS racers built by the factory had a weight-saving window dealee - the window crank mechanism was gone and in its place was a leather strap belt. To raise the window, you pulled on the belt and latched it into place at the height you wanted. I have a picture of it around here somewhere, I will look for it..

Good idea. Done.

So what are the easy things to do to drop weight? I am wanting to make my 80 into a more sporting toy. Is there a thread on this already?

Nope. That was me in her car. This was a special purpose trip. Otherwise I would have been in a 928.

It weighs about 3100 pounds. 6th gear is 0.56:1. At ~70 the lump is turning about 2000 RPM IIRC. Most of the time the mileage is a LOT lower.

You kiddin'? Sleeping in my bed is more fatiguing that a long drive in a 928. But, the Z06 is pretty comfortable on trips.

There's a reason we call it the Fantastic Plastic.

Lowering weight not only improves power to weight, but also reduces lateral forces in turns. However, for top speed guys lowering to weight allows it to lift more easily.

Isn't that what upside down wings are for?

Top speed guys do not want the drag associated with those upside down wings...

"BTW the new bilstein suspension is awesome."

I just put my bilstiens in the other day. You are completely correct- they're flat out AWESOME.

My GT weighed a portly 3700lbs once, at a real race..(one of my first with PCA) With driver and rollcage, as we came off the track. I now race at about 2700lbs, again with driver in all my gear. You will get your a** handed to you by many many lighter, but less powerful cars, if you try to run with them at "full weight" in a 928. Look at it like this..it'd be like having the front four of some pro team in your car as you try to get it going, stopped, and turned. Well, maybe just 3 of the front four..And 50 lbs of wiring is very conservative as an estimate. I just got an additional 50 lbs of wires out of my car after three years on the track. Finally got around to taking the time to really go through the chassis and remove all the crap I never used anyhow. I have heard of 928s in Europe racing at 2300 lbs..now that would be nice.

Do you know who? Seems way to low, especially if it has a full cage.

Speaking of wiring.... other than the essential wiring for making the beast stop and go - motor (EFI, Alt, etc.), gauges, abs (?), what other electrically-driven equipment and associated harness are left (either from a 'is desirable' standpoint or 'required by the regs standpoint?'

Headlights? Marker lights? Front wipers?

Here is an article I found while surfing the net. Just some info in general on weight reduction of the newer cars.
