A great product which is important to a vehicles handling that cost only afew dollars. This is a Graphite look alike balancing weights which you would use to balance out your vehicle. I bought this to use on my Touring GP car, but you can also use it on EP cars also. Dont waste money by buying weights like these but from a brand name company because your just blowing your hard earn money away, because it does exactly the same thing, but this one probaably looks much nicer then the other lead ones. It also has a adhesive backing on it so you can apply it anywhere without it falling off. The Graphite pattern makes it look really nice aswell, because it looks like it is supposed to be there although alot of people look at it and dont know what it is. I use this when i using my Tweak Station ..
