lol, okie dokie, you weren't kidding

That's awesome.

You can:

-Remove the rear chrash bar (or drill it out, as I have done)
-Switch to a 987 Engine cover, saves 1.7 kg
-Remove one of the two horns, Saves basically noting ;-) But still..
-Remove passenger side wiper
-Get lighter wheels?
-Make the "Gt3"-center console delete
-Go for a Lithium battery
-Carbon hood / trunk
-Carbon fenders
-Remove the fog light bulbs..

Ok, now I´m struggling.. ;-)

My 99 base is at 2415, goal is 2200 lbs. or less?, street legal. Then I'm taking a Sawzall to the body, chopping off almost everything overhanging past the front and rear tires.

WizardSmokey, nice, did you remove the roll bar? Edit; answer is custom welded in roll bar. I remember your thread now. Need to re-read it.

For the points Robert986 mentioned:

1: I had no engine cover at all, unless I was at an SCCA event, but the one I did have was about halfway cut away to make room for the intake.
2. Horns long gone.
3: Windshield wipers, linkages, motors, hell, the whole damn assembly was gone.
4: My wheels are already pretty light, gonna be harder to go much lighter without spending BIG money.
5. I have the GT-everything delete.
6. Lithium battery would save a solid 30 lbs or so.
7. Carbon body panels are hideously expensive.
8. Bulbs? Hmmm......

2,200 lbs is going to be very, very difficult without already chopping a lot off. Mine was at the absolute minimum needed just to drive around (much less street legal) and was still 2,460 (but still perfectly balanced!). You could shave a few pounds more with a lightweight battery and lighter wheels, but that would still have you at about 2,400 or so. I even had a power steering delete and a/c was completely removed except for the lines under the car, and those are aluminium and weigh nearly nothing.
