With A/C, radio, full interior, carpets, no rollbar, no fuel, that car hit the scales at 2,880 lbs. Exactly, 250 lbs lighter than a stock 996 GT3 with no fuel.
I ran it with no carpets, no glovebox, no door panels, no passenger airbag, no side airbags, no passenger seat at the 2006 SCCA Solo Nationals, it hit the scales at 2,770 lbs.
These days there are parts to make it even lighter. The 997 GT3 RS wheel carriers (4 of them) allow the 996 to run 10mm lower and the save a total of 10 lbs. There is a lighter flywheel that saves another 6 lbs. The Aluminum doors from the 997 Turbo/GT3/CayR/Spyder fit the 996 GT3 and save another 34 lbs. There are seats from Recaro (Pole Position Carbon) with aluminum hardware that save another 8 lbs per seat. The Li-Ion batteries (I have one on my Fiat) can help on another 8 lbs over the LW battery I had in that car. It is very easy to get the car on the 2,800 lbs range with no fuel and full interior.
I had 2 sets of BBS Magnesium wheels that saved 30 lbs over the CCW wheels. With these wheels, dry weight would be 2,770 lbs with the additional parts above.
Then you can add GT3 Cup bumpers, rear deck lid, carbon hood, carbon fenders, cargraphics carbon doors, lexan RS rear window, Cup lexan rear side windows, and the cargraphics LW carpets. All these modifications get the car 180 lbs lighter. A little under 2,600 lbs with no fuel, and full street legal with AC, radio, airbags, cats, upholstered interior, power windows/locks/mirrors.
...I'm thinking on building another.

Good GT3's going in the 40's plus what you already learned would make for an awesome street / track beater!
I would just buy a 996CUP and 996street and move plates and drive it to the street anyway.. I don't think it would be an issue in Florida.

I'm actually looking for one with a Salvage tittle, to put it back on the road. Something with flood damage or a minor accident.
The thing is that with the IPD plenum and headers, sport cats, the 996 GT3 gets on the 420 Hp range.
I drove this car at 380Hp (bone stock engine ecu, headers, cat) and 2,770 lbs on 285/335 tires. It was a monster. My car had the 4.00:1 R&P gear back in 2005. The acceleration was insane. I chased a F430 Challenge at California Speedway with this 996 GT3 (at 2,880 lbs) and the Challenge could not build any distance on the straight. The F430 Challenge is faster than the Scuderia in straight line.
At Englishtown when it was on the 2,950 lbs range with Dunlop SSR 245/285 tires, it ran 11.82 on the 1/4 miles at 120.6 mph, or something like the times posted by the 500Hp GT3 RS 4.0. However, I kept working on lightening the car.
At the track it ran even with the 996 GT3 Cup cars on straight line, and then gaining on them beyond 130 mph.
2,600 lbs with a rollbar and full interior is feasible, 420Hp and a re-geared tranny. Cup bumper and splitter, Cup decklid and Wing. A street legal 996 GT3 Cup with no nannies like the newer beetles.

I like where you are going with this. You have the knowledge to tinker it to perfection. Build the final track car. dependable lightness, the best suspension and handeling car and just add the 4.2 Orbit keeps talking about..

Just saw it on a previous page - Front: 18"x10" ET32, 6 3/4" back spacing. My front CCW is 18x9 +50mm 7" backspace and it does not seem to be any space left at all there, even considering 225mm front eibach springs and rotated upper mounts to move shocks deeper inside. i do not understand really how could 10" wheels fit there.
Or was 996 gt3 front different from current 997 NB car?

Rad, did you have 10" rims to put 285 in front? How did you manage that, I mean even 9.5" wide wheels do not seem to fit there? Or did you roll your fenders to make it fit?

Rad , many thanks for all that info
Many questions come to my mind
1 camber and toe
2 damper and rebound on the moton
3 lithium ion, what where
Note: the exhaust system on the seal gray seems to be stock am i right?
nium
i just looked in to the ipd plenum hummm interesting
Thanks in advance
Marc

996 is different than the 997, the 996 is actually narrower. I fit 10" wheels to a friend's 997 GT3 last year with 285/335x18. Wheels are Cayman rear from OZ plus a 5mm spacer and stock suspension (18x10ET35). Strut mounts rotated, 7mm shims, PCCB car (different carriers), and fenders rolled. He's still running them.
so you say CCW in 18"x10" ET32, 6 3/4" backspace will fit into any 997.1 NB car without rolled up fenders? or does it need more space on outer side?
Does it also need a spacer like a cayman wheel?
As I rotated strut mounts my 9" wheel moved inward for a about of an inch, but it is just 9" wide rim, 10" wide rim still probably will protrude out no matter what...

Your car uses a different wheel carrier, it is a Boxster/Cayman/Carrera hub with different track width, so the GT3 geometry doesn't apply. The Boxster/Cayman/Carrera use a different front fender as well.

yep, i did not replace hubs. I am quite OK with how 275 rubber sits on 9" rim now so I will keep it like this for a while as i do not want to touch fenders yet anyway.

Front: -3.5 degrees
Rear: -2.5 degrees
Toe:
Front: 0.15 degrees toe-out per side
Rear: 0.25 degrees toe-in per side
Moton:
Front: 3 clicks compression 5 clicks rebound (starting from 0 or full soft)
Rear: 4 clicks compression, 5 click rebound
Warning: I like my cars loose. Loose is fast, tight is slow.
Li-Ion:
Many brands, I went with LithiumPros for their Mosfet circuit protection, I tested it and it works. My Fiat is a deep battery consumer when parked. Porsche makes one, that's what I would use for the 996 GT3, straight swap.
I had muffler bypass pipes, I never liked the 45 lbs hanging behind the rear axle. These days I would do headers, sport cats, and an Akrapovic Titanium muffler, quieter and more power.
Do the Intake plenum, it was one of the biggest changes with the 997 GT3, tune the car on a dyno, then check for power around 8,200 rpm, and if everything looks healthy, move that redline to 8,500 rpm. Buy spare engine just in case.

The CCW 10x18 ET32 doesn't need a spacer in the 996 or 997 GT3. The 10x18 ET40 rear Cayman wheel (OZ) needs a 5mm spacer on both the 996 and 997 GT3. Both chassis need the fenders rolled and pulled to run 285.
Your car uses a different wheel carrier, it is a Boxster/Cayman/Carrera hub with different track width, so the GT3 geometry doesn't apply. The Boxster/Cayman/Carrera use a different front fender as well.

In the 996 and 996 both the Carrera and GT3 use the same parts. Then at the showroom, I have noticed the Carrera has a thick fender inner lip, and the GT3 has a rolled lip. It is like Porsche rolls these fenders on the production line, but I cannot confirm.
