Carl, I just weighed my GT4 with reg seats, steel brakes, extended leather w/ platinum stitching, fire extinguisher, carbon trim, smoker's pkg, and a full extended tank of 93 at 3117 lbs. What is your take on this vs the Porsche claimed curb weight of 2955 lbs?
Not too far off...
Weights:
Radio delete- 9 lbs
AC delete- 18
Small fuel tank- 20 (when both are full)
Lightweight buckets- 24
PCCB- 36 (est)
~107 lbs total.
So your 3117 becomes 3010. Fire extinguisher- 10? Trim, smokers package, etc another 10? 2990. Then Porsche weighs per DIN, meaning a 90% full tank. 1.6 gallons is another ~12, so we have ~2978. Call it a 20 lb gap. If the lithium battery was allowed for the measurement then we're more than there (30 lbs). Not sure what the tolerance is on the DIN standard, but realize that Porsche quotes weight for the lightest possible configuration.
I would say you will not find a lighter car than the one Porsche gave sport auto For ring lap. This car is small 54l tank, delete klima, delete stereo, and its no clubsport pack, but its bucket seats and ceramic brakes. Hard to find them gt4 lighter than that i guess. Its 1378,5kg full tank fuel. My car is 1430kg full tank fuel. This is without driver in car!

3039 lbs. Lithium battery saves 30, 11 for 10% less fuel... 2998. Where's the missing ~43 lbs? No other options? Need to look up the DIN EU6 reg this is weighed to.
3037 lbs with all the lightest spec. Mine 3083 stl brakes and std seats. 46lbs less for deleting the AC,radio adding LWB and PCCB plus an additional $12,000?carl

I don't think that car was such an extreme stripper. From the pics it looks like it did have the standard AC and Radio/PCM. Also Sport chrono and even leather. So the weight saving would only be from PCCB and buckets (~60lbs). Plus probably more fuel weight if they tested with either 90% or full tank (of the smaller tank) vs your half bigger tank.

AC and radio are 27 lbs, leather and sport chrono might add 10? Add those to the 2955 lb base weight and you're at 2992. I came up with an estimate of 2998 above- I'd call that essentially the same.

What I am saying is more or less its not going to be easy to find many accuall cars on streets lighter than this. As it not that common people Will totaly skip even ac, sure klima but not ac. And the small stero. This car is also small 54l gasoline tank wich was full when it was on scale. Most common is bigger 64l gas. I remember the M3 CSL it was only ap 15-20 % of all they produced that totaly delete radio/klima. My guess is it Will be even less % that skip these things in gt4. But it Will be intresting to see if we ever see this car on the streets.
Checked the strut mount to see how much adjustment is left with -1.5. as you can see its almost maxed out . i dont think you can get much more than -1.6 without adding shims. i may try a track day with the -1.5 and see how the tires look?

he has the headlight nipples. This means extra large washer bottle to the tune of an additional 6 kg or 13 lbs. First thing i do when i get the car is to drain it to the minimum level.
