I what to lighten up my new 964, I do what to keep A/C for the those hot track days. Please let me know what you have done.
In the past I removed all the things I don't need, and change parts for Fiberglass.
I got my longnose down to about 2100#s
But I don't know these new cars Thanks for the help!!!!

You can gut all the "easily" removed pieces (AC, all climate parts, all interior, etc) and get to about 2500 lbs. Below that, you need to strip it to the tub, clan the tub and start from scratch. If you keep the AC and heat, I doubt you'll get below about 2800 lbs. Fiberglass does not save much weight (except for the doors, engine cover and hood).

There is an Allied Trucking rental office near me that has a calibrated scale (what they use it for I'm not sure). My '90 weighted in at 3040 with a 1/2 tank of gas. Cost me $5.00 to get it done. I might do it again now that I've stripped some exhaust.

Mine gets weighed each time it gets an alignment (with a corner balance). That's been pretty frequently lately since I've had many changes to the car and the suspension that required the alignment and balance.

At the track during test days (Roebling Road).

At least in Oregon, the trucking scales on the highways are open to the public, just drive on. No charge. Especially on the weekends, there is never anyone waiting. Quick and easy.

My car was on a diet until I bought it. Keeping the heat but no AC the PO got it down to 2,813# I have since re-installed the AC. My race mechanic weighs my car for me but here in the Dallas area I would think RUF, Zims or Mayo would be able.

William,
Are you going to the DE this weekend, I would like to know how the new track feels.

I am not, and I would like to know about the new surface also. I might slip away on Friday the test day, but it is unlikely.

They are re paving Road Atlanta early next year, I can't wait. Hopefully they don't raise the prices on the DE's

I'm assuming you've emptied the front compartment completely (for more understeer and less crash resistance!).
At the back taking away the undertray, rear wiper and motor, and cat bypass plus primary or secondary silencer bypass gets rid of a surprising amount of weight in the right place.

For the pho schizzle on lightening, do a search for posts by a German RS pilote with 'pauline' in his user name. This is a chap who would drill his wedding ring.

Another user, Robert Linton is gradually making an entire 964 out 'unobtainium', which is fun but not practical for most of us..

The rear interior saved me some weight (interior quarter panels, the large leather matt behind the rear seats, the rear seats themselves, rear wiper (plugged hole with a stopper). Also, RS door panels (get rid of your front speakers!: ) will save you a few lbs also (I believe 7 lbs/side).

I had thought about removing the spare tire from mine but was of the mind that it was taking weight out of the wrong end of the car (being already rear-weight biased). What is the general consensus of lightening the front end in terms of affect on handling? I've already replaced my secondary with a J pipe and the stock cat with a bypass. Not sure how many net pounds that shaved from the rear. And is the spare really of any use in practical terms if you do get a flat?

Removing the spare reduces crashworthiness - to what degree I don't know. While rear weight removal is ideal, anything you can take off the front is good too - you can dial out any resulting understeer (if there is any) with suspension adjustments.
