Sounds like a plan
I will post you some pictures of my car in the next few weeks.
My son is at uni and is useing it as a chassis project.
I dont want to show the frame untill he has run it through the computer and confirmed it is safe.

My Mk2 Rossa in road trim was well over 800 Kilos. I seem to remember that a selling point of the K3 was that the body tub itself was lighter than a Mk2.

And my Mk2 without its roof bolted on had the torsional rigidity of trifle. So be careful where you remove weight from.

http://www.ijohnson.demon.co.uk/gtmoc/rossa.htm quotes Rossa at 700kg and K3 at 820kg, wonder if they're the wrong way round?

Anyone got original brochures with quoted weights?

I have an original brochure for the Mk1 and it says 700 kgs in road trim.

If my Rossa II was driveable right now I'd put it on a weighbridge to find out.

Anyone got any more weights quoted or actually weighed?

I did say body tub and it was a magazine quote.

As for my car it was fuelled to go with spare wheel, roll hoop, roof etc. But I put it on a proper weighbridge with no driver or luggage 840kg.

840 kg - interesting, seems like I'll have to work harder to save weight and aim for more bhp

Hello
These figures sound alot when you consider that a standard Mini in road trim weighs 720
How did they ever sell it as a sports car?

Mine was never remotely intended as a lightweight. I think I could easily have dropped 40kg without a lot of work at all. But I only actually measured it the once and I thought I'd let you know what it was.

I'd be interested to know if anyone else measures theirs.

OK, I weighed a few bits (bathroom scales).

Rear lower section of bodywork (bit with bumper, lights and luggage bay) - 15KG

Engine cover section 12 KG.

Will weigh other bits as convenient - would anyone else be able to post weights?

Allen

Well, car is mobile (if not actually mot'd ) Weighed on local public weigh bridge, accurate to 20KG I believe)

All up weight (hard top, tank 1/4 full, no driver or tools) = 780KG

Not very scientific but front of car
(edge of bidge to middle of wheelbase) = 390KG

Rear of car (edge of bridge to middle of
wheelbase) = 430KG

(as I under stand it the front and rear weights should add together to make the total )

Good news is that I've saved 300 grams fitting a new set of different wheel nuts

Guess a full cage will add a good 25KG

Anyone else weighed anything recently?

Yes - 14 stone +

Further weight savings:-

Removed engine cover hinges and now fitted with dzus fasteners - saved 2 KG

Recaro seat weighed at 19 1/2 KG One seat

Remove seats replace with non recliner seats at 6 3/4 KG each seat

Total weight saved so far 27KG and 800gms

Only down side, new seats are a bit on the snug side

Now stripped out the dash and mini heater. Replacing heater (4 KG) with one weighing 1.2KG.

Also have an Acewell digidash to fit, so should save more weight.

Total weight saving so far 30.5 KG

Acewell dash and heater fitted, complete with new dash, saving about 5 kg. Total now approx 35.5 KG
