carbon fiber hoods

[j.fro]

The hood (that's what we call it over here ) clam shell, and trunk lid are the big winners. If the hood saves just under 40lbs, I'd put the clamshell at 10 and the trunklid at 15-20. The fenders would probably be worth another 20. The doors are a different issue. Those shouldn't be swapped unless you have a full roll cage with significant side bars. On top of that, you'd have to lose the windows.
The front and rear bumper covers in FG are actually slightly heavier then the stock plastic.

So j.fro, if your numbers are right, we would be looking at a weight saving of around 90 lbs (about 40kg "down under")? I know how different my car feels with 90 or so lbs of groceries (a few boxes of bottled water) in the front boot (trunk). It doesn't sound like much, and I suspect straight-line speed would not be improved by a great deal, but the car would feel much more nimble.

Has anyone here been serious enough about weight reduction to get their cars below 1,000 kg (2,200 lbs)? So many threads on this board are concerned with people going to great lengths (and great costs) to extract a few hp. I am yet to see someone spend the same sort of time and money dropping serious weight, which in my opinion, would make these cars a LOT more fun.

As my Boxster is a 100% dedicated racing car, I am constantly looking to reduce weight - I would love to get under 1000kg, and hope to do so one day.

But I also have to make sure the car does not get to light as that will push me into the same class as the 997 Cup cars and then I will have no chance

What are you weighing in at? I saw the pics on facebook, roll cage looks fantastic.

Currently it is 1140kg dry. Factory hard top etc does not help

I would like to replace most of the body panels with fiberglass, but the cost is a bit to high for me at the moment. Getting the parts shipped to me in Finland is very expensive, and there is not much available used!

I think getting under 1000kg is hard with a Boxster. SVP have one racing car they have built which has had the shell acid dipped to remove all the rubber stuff from under the car etc, and that is siting at 1030kg. But like I said, would be cool to manage to get under 1000kg one day

I was thinking about doing this but never found one that lined up perfectly. There always seemed to be a fit issue.
