These integrated mid sponsons were designed after our tried-and-true #219 mid sponsons which drastically increase rail grip and stability in turns and provide a tighter turning radius. These mid sponson blades are only required if you are racing in an IJSBA sanctioned event. IJSBA requires the mid blades to be attached to the rear sponsons in order to be considered 1 sponson. These are a direct bolt on to your existing JCRACING SXR1500 Rear Sponsons. Get the added benefit that mid sponsons offer while remaining race legal.
If you do not plan to race any IJSBA events, try our detached #219 mid sponsons which come with full instructions for mounting them on the SXR1500.
