+80lb weight loss for the track hounds...

Weight loss is a building block approach. 80lbs here, 70lbs there, all added to the 50, 45, 37, 6, etc, etc, removed elsewhere will add up to significant saving these. With enough seat time, you will be able to discern 80 to 100 lbs for sure. Probably not on the street, but certainly on the track. My car will sneak just under 3000 lbs which is very low considering the fact that it has a 997GT3RS clubsport roll bar, 380 brakes, etc, etc. A stock 996GT3 is around 3150, a GT2 around 3200 and a stock 996TT 3400-3450 by comparison. Keep in mind those #s are without roll bars or any other safety equipment.

So yes, accordingly this kind of weight would turn it an entirely different car !!

The weight loss wont help you much in terms of excelleration but on the brakes and in curves it will help for sure.

Thanks Steffen. Fundamental physics will tell you that it will take less time to accelerate less mass to a given speed with the same hp. There is a simple formula for that. Same principle applies to braking and cornering. Lighter cars simply perform better on all fronts.

I know, but the effect will turn out more while braking and building up g-force in curves, Probably you shaved 0,1 sec off from the 60-120 mph time. Thats like full tank against empty tank.

Burning Brakes
I wonder how those would hold up on a cab? I can tell you for sure the cabs flex......when I exit my driveway at a 45-degree angle (to avoid front lip scrape) with the top up, I can hear groaning at the latch point....the car is twisting. Would repeated stresses such as those eventually crack those doors? I am not in any way knowledgeable regarding carbon / Kevlar, just wondering..............(and bored at the moment)

Also, less weight helps on your consumables.. Less stress on the tires, the brakes, all the other wear items. It may not be a lot, but every bit adds up.

Gorgeous doors. I've been perusing the Manthey site and can not find reference to 996 or 997 parts, just 991 and 981 parts. Did you special order them? I've been looking for something similar for 997/987 fitment.

They are not on their website but you can call them and order them. They are in their older catalog. They do make them for a 997 also. Let me know if you need help sourcing them as I can get them stateside with about 4-6 week lead time. Manthey will NOT ship directly to the US so you have to figure out a workaround to get their stuff here.
I have a 2012 Cayman R, it already has the aluminum GT3 doors, so I my weight saving is going to be less; according to Porsche the GT3 doors save 33 lbs. over the steel 997/987 doors. Currently, I only have a harness bar, but a half cage is planned for this year, but I do not have plans for side intrusion bars. I do wonder how safe these doors would be in a side impact compared to the OEM doors?
