I think I'm the MIKE you are referring to , Nice job, and very nice PICS.... ........I can't believe someone actually believed me .......good for you, you won't be dis-appointed.......I only use ONE on the rear wheel ...But I'm a dare Devil .....The only thing I would caution about is the distance of the front wheel anchors from the front tires / wheels. I don't think it's possible that the Spyder can move forward though.....and this is only as strong as the weakest LINK which is the ANCHORS .....I think your's are FINE....................Mike
