Hood from fiberglass or similar will cut ~15 kg
Trunk lid ~10
Front fenders ~10
Windows ~20

Sum 55 kg or 120 lbs.

Stripping the doors easily another 55 kg!!

Thanks for the numbers!

Stripping the doors easily another 55 kg!!

I suppose you are referring to the "inner" sheet metal and the "thick" reinforcement? I know the doors have this heavy-duty metal inside, running the length of the door. Along with the welder I was contemplating cutting it out...

Off Topic (as usual)

Can I flat tow the transaxle car? All 4 wheels on the ground.

I'm afraid of gear lubrication (or lack of it) since the oil might not get to all the rotating parts.

Alternatively I was thinking of detaching the 2 halfshafts on the tranny side before towing.

Opinions?

Otherwise I'll get a dolly and put the rear wheels on the dolly.

OK back on topic

I may just sell the recaros and put in the King Dragon race seats in an effort to reduce weight.

OK off topic again

Micke for the rollcage, in the back section is there a rule (let say for your racing organization) which says the bar from the main hoop to the rear section of the car has to be straight? Or can it be slightly bent/curved (kind of like JimGreek's cage) so I can have more room in the rear? I didn't see any rule like that here.

Micke: The fenders I have weigh in at just over 2Kg a piece. How can you save 10Kg on that?

Zamani: Tow away, how do you think the GB is lubricated normally?

Doors:
sound barriers
inner sheet
window mechanism
thick window frames
side protection

My GTV doors were 27 kg each including windows. I guess the Milano doors are about the same.

The only change to the drive shaft is the addition of the "plate" at the front coupling to reduce the "twisting". Again, we'll see if I'll be changing couplings daily...
Oh, and I have an inherent weight advantage against JJ (the secret: running daily). Though, can't match Zamani

Jes,
You need to get some of these..... Solid prop u/j - proven with big power/torque. Also notice the extra beefed up webbing on the Autodelta factory clutch cover - another weak point, with high revs and power.

Mats:
didn't weigh the 75 doors so it was an educated guess. My GTV fenders were 20 kg so that's "where I pulled my numbers from"

Z'man:
When you tow the car the gearbox will rotate quite normally (unless you go real fast with wheels off the ground). So, the lubrication will work normally but without any power from the engine. It will last approximately 2 374 562 km (or miles for ye yanks).

I'm not sure about the cage but the front tubes are often bent for clearance. I think it's allowed. Stiffness will suffer of course. The diagonal bar is always straight as far as I've seen. This you can make removable if you need transporting power.

So, now point in touching those!
Does anyone know how close you can get in weight of carbon fiber hood and trunk lid by simply cutting out "excess" sheet metal from the backside of stock hood and trunk lid? Any guesses at the weight difference of gutted stock hood and trunk lids and carbon fiber parts?

20 kg.. i need fiberglass ones on my gtv baddly then

? how u remove them Micke they are welded

yes 75 fenders are very light=thin

Some more solid prop, and re-enforced rear g/box mount - with nylon bushing. Group shot of my fast fleet

Jes,
If you are using composite parts for rull race application, then hood and trunk lid strength and rigidity may not be very important. (bums dont jump on your hood at the track the way they do on some streets). If this is the case, a carbon/kevlar part could be extremely light. I dont want to speculate on the exact weight, however.
I just spent all of my money on a big roll of IM7 carbon fiber which is about the strongest by weight that exists. I think it is used on the stealth bomber! Arms manufacturers buy the entire world supply so it is very difficult to aquire. I bought a roll that was the excess trim from a military aircraft supplier (they wouldnt tell what project they were building...top secret

). They get it in 100foot wide rolls and they cut a few feet of excess off and roll it up.
When I get it I will be able to estimate the weight of projects to some extent.

That is a stunning collection of whips!

One more point about body kits:
Evo kit integrated corner pannels would save some weight, but more importantly allow wider rubber.
I dont know how much wider though.
I am done now...

Andrew,
Are those pics from your Rouse GTV6? What do you have in the center, or is it a one piece solid shaft?
