Thanks mattjo, I got the set on ebay for around £20-30 for a full set If I recall. They aluminum and ultra light. Although the colour fade, so for a while they where pink lol they now aluminum with a slight red tint. Because they are soft if you use a wheelnut drill and don't put it on correctly they can twist. so have one slightly twisted nut. still able to screw them on. When I say light its like a a difference between a full can of coke to an empty one. (well you get the idea) 
On ebay i went for the slightly cheaper version so not sure if the more expensive one holds it colour.
ah ok found them here they look better quality than the ones i bought just make sure its 12x1.25 hmm might have to get a new set, these look proper anodized. Think i got ripped off
