It's sharper, sturdier, and gives a closer cut than the previous model. Durability is greater, allowing you to cut several sets of tires for that instant grip feeling on new tires!
Why is it better than sanding?
Sanding damages the centre of the tire, as it heat cycles the rubber, and also leaves a rough finish. Using the Tire Line Remover V2, you aren't adding heat, and are leaving the rubber in it's natural form with its natural shiny finish. So when you hit the track you are getting 100% performance on a new set of tires.
Easier, faster, cleaner, with more grip... what's not to love!
