why not to sell this product as for racing purpose only??,not for street use,without any warranty and at owner risk,this could solve the legal problem,with sticker with write"install at your own risk"The issue is a lot more complicated than that I'm afraid.
I'm not saying what is out there is dangerous (I use one myself) but if they won't stand by the product (legally) then more needs to be done before I'll supply it.
