I bought my car fitted with a SPA digi speedo. It suddenly stopped working recently and i have discovered the little magnetic piece for the sensor to
pick up has gone missing
I got intouch with SPA and was told they do not sell them as spares but Demon Tw££ks do, and sure enough it is.... @ nearly £30+vat+postage 

for
a frigging magnet?
So i have found a few places which will supply me a load of magnets for less than a fiver
but i need to know how big it is?
So if anybody has one of these Speedo's could you please measure your magnet and let me know?
I have a feeling though at that price this magnet must be something special!
and my idea may not work
but to save me £30-40 its worth a try 
Cheers
Mike
You could always ask these guys for a sample when you find out how big you need it.
ABEL MAGNETS
Hope it helps!
I'd stick a fridge magnet on to see whether it works or not. It does with Sigma type speedos. You can always take it back off again.
I should think it has to be a little more powerfull than a fridge magnet. i have found several places including Abel Magnets who can supply me with a
disc shaped magnet, all i need to know is how big? I'll probably take a guess and get some around 10mm dia and 3-4mm thick.
Thanks
It is 6mm dia. and 3mm thick. Make sure the poles are marked because it needs to be mounted north pole down or it will not work correctley.
Cheers
Unfortunatly Abel Magnets are out of stock for that size

Update:-
Had an email back off Demon Tw££ks saying the price for a magnet is £2.86 +vat not the £29+ in the catologue
But still, i can get 10 of them for £4.99 elsewhere which works out at 49p each
