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 :mrgreen:

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?

Regards,

Allen

Well, car is mobile (if not actually mot'd :shock: ) 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 :mrgreen:

Guess a full cage will add a good 25KG

Anyone else weighed anything recently?

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 :mrgreen:

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

Total weight saving so far 30.5 KG
