It's got a 20 litre capacity, this will be a prototype and once it is fine tuned I will be able to offer them for sale.
The rear discs are excellent (I'm just about to swap the drop brackets from steel to ally, so there will probably be a set up for grabs if anyone is interested), I'm using Ford rear calipers with a standard mini disc set up.
I don't have anymore photos at the mo, but I will take some more when I swop over the drop brackets and post them in Photobucket.
Cheers for the comments
