Vigor 3,0mm Gear Diff O-Ring Cutting Tools For Yokomo BD8/7

Sometimes the o-rings in the diff are too tight and then they create too much pressure on the outdrives. This influences the driveability of the car as it is not as consistent as you may like! With the new o-ring cutting tool from Vigor you can cut the o-rings down a little bit and this will make the outdrives turning lighter in the diff case! Just place the o-ring onto the tool and cut it down with a sharp blade! It is very easy and you will achieve great results with this tool from Vigor!
