Hi All!

Anyone know what the approx weight of a Mk3 MM is? I'm thinking of getting a trailer for mine, & was trying to find out about legal towing weights etc. Anyone any experience/info?
btw, don't worry, I'm not thinking of woosing out (is that a word?) completely - just might be handy for the odd long distance event...

Why not drive to your local waste recycling/refuse  centre, they usually weigh cars going in and coming out to determine the charges.

Thanks guys, that helpful - I'm sure it must be similar to Tom's, the cage will more than make up for the lack of trimm & passenger seat I'm sure

Don't worry Joost, I'm just jealous of your posh trailer - Doubt if I'll end upi with anything that grand

I'll try Neil's tip of checking out the local tip - Hope they won't want to keep it...

It is very light! No carpets etc, but a roll cage of ChrMo is very light but youre still adding weight. A standard MM could be lighter.
A MM is very light at the rear. Very bad front-rear weight ratio. So if a MM is becoming lighter at the rear the handling will go down. 100%
In BCT in germany the racing Minis handle better because the cars are more balanced. If you want a better or lighter race MM then you should make a mid mounted engine behind your seat!

Tom's right - That's pretty light!!!

My car has a steel cage, so probably a bit heavier than Tom's,.. We'll see when I've been to the weighing place...

I was thinking of going down the beam axle route too - maybe it's not such a good idea?

Re IMM cd - Sorry, been very busy with work all summer so far    I'll make it up soon - Let me know if anyone would like a copy - pm me your address & I'll add you to the list No charge - It's only a CD!

Guy,

My car weighs 600 Kg with a steel cage. It is about 400 Kg on the front and 200 Kg on the back.

A beam axle is a good idea, you just need to find someway of removing the same amount of weight from the front.

For Guy: tnx for the cd ill send my adres etc ill wait on it  

For Allan: I have a normal steel beam axle because an aluminium would be too light! it has adjustible radius arm holes. BUT you have to use coilovers for it... I have ordered the lowered gaz ones! For the front you can save weight on many thinks: aluminium radiator, Aluminium cilinderhead, mini sport alloy calipers, magnesium rims, a lighted subframe (tom's subframe) and coilovers instead of the alloy tubes and ruber cones (dont think it make much differance  ) How lighter you want to make the car the more pricie it gets... Ill make photos of my rear setup when its finished, first I need to finish the body nearly finished with it

Cheers

I just wonder how much it's worth trying to save a bit of weight when you still have that big lump of A-Series iron at the front?

Actually I chopped out quite a bit of weight when I rebuilt foggy's front end. Now the original flat nose panel and lump of wood supporting the new panel are gone, and it's much easier to get at the radiator and the front of the engine.

Now that is a saving, steel app 7,9kg/liter, aluminium 2,7kg/liter, so you will save on that, but new problems occur when you copy a steel A/A+ and make an alloy one. The technique is 1950s, the best to do is fit a new engine from honda, fiat or whatever. Alloy A engines are non original, then one could also drive with honda engines imho.

New front end looks good Rich

Do you fancy sorting mine out, seeing as how you're such a dab hand with the fibreglass???

Got to stay original I'm afraid - cast iron block it has to be... maybe I can loose a bit of weight myself...

i did hear someone had got hold of the rover ali A series block and was measuring it up, there is a propper couple of ali blocks in existence but i presume there is no decent tooling for it!

i will be building a 1380 A series with a TWIN CAM BMW K1100 head on it in the future, has anyone tried one of the ali heads that are available?

There are normal A series alloy heads for sale. You can buy them new and are the same as a normal one! But they weigh a lot less!

at the imm in 1999 there was a rough machined aluminium A series block (can't remember on who's stand it was),
I have had it in my hands, something you can't so easy do with a cast iron block...

I actually 1 ally a series block.  It was made in the sixties as a BMC project a total of 7 were cast.  It weighs very little but is 998cc.  I did bring it to Castle Combe a few years ago.  I also have a ally aquaplane head to go with it!

Pete

By the way Granny is 593kgs ready to race, should be possible to build a road car in the 530kgs bracket and a Mk3 or ealier racer to about 550.  The Mk4s are quite a bit heavier.
