Product Description
Out with the old, in with the new....Black Edge from Nall Speed Prep takes everything good about Black Sand and makes it better. Gone is the separation you get when you mix Black Sand with other preps.
Black Edge is designed for sandy tracks with low bite. Best results with tires reading between 45-52. The more wipes you put in the tires, the more grip you will get. Also really good to use when tires are hard and you just want to put an aggressive bite on top to make the tires fire off.
