These are simple parts but having them pre-made saves a lot of time when your sprint gets run over and that top wing is torn up. Ron at Rocket Products researched and tested several materials to find the best combination of strength and flexibility and is now releasing them for your Sprint Car! Available in black or white, and packaged in quantities of four (you always need spares!). You will need to supply the hardware (none included).
Also shown is a handy tool (in orange color) to drill the holes for the struts to assure your side plate is 90 degrees to the wing top. This tool is NOT INCLUDED but available for purchase by clicking this LINK.
