Being low has nothing to do with whether or not added camber is needed. Additional camber aids in getting more contact patch from the tire to the ground during cornering. Being low simply lowers the center of gravity. Two totally different aspects of suspension design. MINI's are notorious for having to little front camber. This results in uneven front (and sometimes rear) tire wear when driven hard. Adding camber will reduce this wear considerably.
They are not bothering me to have them sitting around. I may take them to the dragon for the swap tent.
Bet they sell quickly down there. You could use them as paper weights, but too much camber will make the papers slide off your desk.
