Obviously, the idea of carbon or fiberglass parts is to save weight overall, cost nonwithstanding.
I am also not a big fan of the carbon look. Except as an accent. If you use if for weight savings, or strength, it is great. I just prefer to paint it... It would be nice to give him all the 928 parts to mold, so we can have CF fenders, bumpers, hatches, hoods, etc.. Not for looks, but as lighter replacements. And if he could also use fiberglass in those molds, it may even be cheaper than new items... And great for racers on a diet...

I like the idea of the hood, especially if it has a functional intake...
But it seems hard to do a hood on the 928 that looks better than stock.
So I'd love to see how it looks when all is said and done.

And I would like to see more interior parts, like the door panels...
It might even be possible to wrap the panels in leather,
with some of the parts visible in CF, for accents...

And replacement pods, and dashboards, is something anyone with a cracked dash or pod should be interested in...

Normy,
As stated before the hood would not only be carbon fiber. I already have the sunroof filler that i got from this guy Constantine from Florida and im also getting the dash and pod done as we speak. If your talking about looks then yes i do agree with you that a carbon fiber hood wouldnt look good but only if your car is anything but black. See my car is black so it hides the carbon look alittle. Now if your talking weight and price, well so far im into the dash,pod and hood for $4500 (nuts right). I would love to do engine modifications but until i see impressive rwhp for a 16v going lighter is my way right now. If you want the hatch done send yours in so a mold could be made because i have no garage to keep my car in without a hatch on.And a diet well i can consider that but the heineken is winning right now.

Doing the hatch with a seam suitable for a Lexan window would be ver' nice.

I think the hood cant weight more than 15lbs or so. CF for that is kind of a waste, BUT, that darn rear hatch. I would buy a carbon fiber version of that in a heart beat!!!! that things is near 40lbs with lexan and not the glass.

Jacquemond ( http://www.jacquemond.com ) are showing this 'new' fibreglass hatch. Looks like a rework of one from the old Strosek catalogue. It's bound to knock a few lbs off, although I'm not sure how good it would be for rear visibility. It looks as if it's designed to still allow enough head room for the rear seats so it probably has enough clearance to not clash with a roll cage either.



I've emailed him to get a figure for the weight of it, I will post it once I get a reply.

Cheers

Thats it!!! if its fiberglass, it shouldnt weigh that much.

Heck, what i would do is cut out the coverd part, although, that is kind of neat as it would basically hide the gutted interior in the back.
I would probably just cut that window out and the side panels and just mount the lexan sheet to the opening with screws

talk about a few lbs!!! only problem the entire rear of the car will weigh almost nothing. thank god for the rear transmission location

We need this!!!!!!!

any help with getting hooked up with these guys would be much appreciated!!!!!!!

Mr. Kibort - put the down, and step away slowly!



I agree, I would rather replace the whole steel hatch lid, rather than just the glass. Molded in reinforcement window straps/rib(s) down the middle would be cool too.

i dont know about that hatch on a 928. I have seen the same style on a 89 style camaro and well it just looked bad. i think i like the carbon hatch idea better. So whos donating a hatch to get a mold made. My guy will definitaly do a group buy. Im game if your game

Here's the reply from Jacquemond:


"Thank you for your mail.
Price of the Hatch back : US $ 1999.00.

Weight 17 kg.
We don't make a carbone fiber hatch back, but we can do one for you.
This will be a bit more expensive, but you ll same more weight. Because we
can do it ( if this is a real racing car ) without the internal part. You ll
only have the external skin.

LEt us know.

As usual from Jacquemond the price is quite steep. This glass fibre hatch weighs 17kg / 37.5 lbs so we are not much better off as Mark's saying the standard hatch with lexan is 40lbs... I also just weighed my spare hatch and glass (no trim or wiring) at 19.8kg / 43.6lbs

However from the email it seems this hatch has a seperate internal skin that can be ditched - let's guess this is 1/3 of the weight as it's probably a smaller and thinner component - so were down to 11.3kg / 25lbs. If you make it from carbon you will probably half the weight (guesstimate), so were down to 6kg / 13lbs. If you're getting rid of the middle and fitting a big lexan window there's probably another few lbs to lose.

Personally I quite like this look and it might work well at disguising/hiding a stripped interior! I've never seen one up close though!

Here's a couple of pics of a german racer with this hatch fitted. Looks good to me. Looking at the shape of the Strosek mods on this car I would guess that Jacquemond has bought the old moulds now that Strosek doesent make 928 parts any more.

DaveW - looks good with the wing.



Looks like you can still see out the quarter windows.

Regarding the Strosek GT Cup, the use of glassfibre gives a saving of 41.7 kilos (91.74 lbs) against the standard car.

Strosek can still sell those parts.

Which one of you has removed the engine firewall to save weight? This was one of the Club-Sport specification.

I´d buy a "standard look" hatch in carbon fiber and lexan window in a minute. I´m in if there is a group purchase or something like that!

Regards!

["""""""""""""" no i wont step away!

anyway, how is this possible . Now, I dont have the details of the rear hatch, but Im almost sure it was around 45lbs. removing the glass and putting in lexan saved 14lbs (so the glass alone is 18lbs) Im going off memoryhere, but if that is the case, the steel hatch weighs 30lbs or so without glass. how is it possible for this fiberglass section to weigh 7lbs more at 37lbs??????

Ill look up the numbers I had before. In any event, if the 37lbs is correct for just the rear shell and maybe even that strip of glass, this mod is not for weight but for looks.

whatcha think?

I'll bet you money that part was built for looks, not for racing.

And I would also bet you that a fiberglass panel that would fit back there could
be made to weigh very little. Imagine a big panel of fiberglass all the way across.
Even that would not weigh that much. The Jacquemond piece may indeed be heavy,
but that is because it was made for looks, not for racing...
