Specialy designed for the 1.3 Jconcepts Ruptures and Bossmans.The reason for our design: Deformation is one of the major issues with 3D or molded inserts. Rotating and conforming are two things inserts are required to do. Our design seems to be the only one that keeps that in mind. Deformation on the contact surface is a big issue for constant grip, as well as conforming. When sub par desings deform they clump, and leave conformity very inconsistent, right on your contact surface! Our Performance Insertz deal with deformation correctly, directionally. As the insert rotates, it does a few very interesting things. First it opens up the Double Barrel Profile in front to promote conformity to the upcoming surface. Then transfers deformation, by design, to the rear of the tire. This deformation gets released at the very back of the conforming surface with a forward pushing action. This gives us our Forward Propulsion Technology, simply powered by clever design, the rotation that's provided by your motor and conforming that's provided by gravity. Now that you know what makes our design superior, the real reason for 3d inserts is side wall strength, this gives you side hill stability, and if done correctly, increased steering performance. There are a few designs that simply don't use stacked layers to thier benefit. When stacked layers are left behind, the structure for side wall stability is missing, and fails as a 3d insert completely. Our design uses stacked layers, and is finely tuned with bevels hidden throughout our protected design. This, along with limited and fully tested stage heights, and our tight fit center rings, gives us superior side wall stability and turning performance. The package contains 4 tire inserts. We recommend venting your tires or wheels when running Slymeballz. They are waterproof, temperature resistant, and designed to give support, so there is no need for sealed setups. ***All products are made to order.
