hi dave, i saw those cosmics in ebay they went for over a ton in the end, was tempted but they need special bolts and you can't get them anymore. i used to have Cosmic superslots (coppies of the original wolfrace slot mags) on my reliant robin,
but in those days you could still get the bolts in most motor factors and as the reliant shares wheels and hubs from a Mini there were quite a common size. You can hold the wheels on with the bolts from nomal alloys but they are dangerous.
in the end i thought the CC Sporting alloys would look like standard wheels when fitted to my Bis. I am not getting the 165/55 tyres with the wheels as it costs nearly as much as a set of tyre to get them sent down, so i will be getting new tyres and face the choice between 155/65s and 165/55s, the 155s seem a lot more common and cheaper and would appear to fit without any problems so i'll most probably go for these. i am guessing the tyre presure would be the same as standard?
