Nope, Spacers have threaded pieces on them, by using washers you only take thread off making your wheel less secure to teh axle.
Just wondering if it would be a good or bad idea to use washers for wheel spacers? I need about 1/2 inch clearance.
I found some 1/4 in wheel spacers on ebay. I really didn't think the washers would be the brightest idea either. I'm pretty sure 1/4 in will be enough. Where can I get longer studs if I need them?
