Pro-Line soft SC closed cell inserts
While at the Dirt Nitro Challenge we were given a sneak look at the soon to be released soft SC closed cell inserts. After extensive testing with Pro Short Course drivers like Ryan Cavalieri, they found that a softer insert is desirable in racing conditions. Like all of Pro-Line’s closed cell foam, this insert is ultra-durable, water-proof and shaped to exactly match the profile of the tires.
