These tyre traction bottle are very good to contain the tyre traction of some brands who give you a shit bottle. I really like the concept, and i've buy it 2 times, but, Yeah Racing, please change the plastic of the white piece, or change the dimensions, because every times i put one of these bottle in the bin, it's because the white piece is over because it's not strong enought when you tighten this piece.
Otherwise, this product is perfect!
Neat little bottles. Good for creating your own tire solution and storing. Try mixing up 2/3 water with 1/3 of Coca-Cola and use that on your tires. As the Cola dries you will get an enhanced grip on your tires. Great product!!
