In my auto 53 class, we have a hunter GSP9700 balancer, but the instructor doesn't carry wheel weights for alloy wheels, specifically, Audi wheels. I would think that the stick-on types would be best, because then I wouldn't need to provide a huge assortment of ENC or ENS type weights, which only come in boxes of 25; i could just snip on/off what i'd need from stick-ons. Should I check harbor freight? Or see if a tire shop will let me buy a bunch of strips of the stick on type? Would NAPA carry these? I was looking at these but i dunno how long they take to ship. ebay perhaps?
