I am planning a fairly aggressive front wing for hill climb use to make sure I can ensure I have good turn in. I also wanted to have the nose cone hinge so that I can have access for service and repairs. I bought again from B&Q some heavy duty stainless door hinges which could be disassembled and the parts arranged to suit my needs. They were £20 but they work a dream. As my proposed front wing will be fitted to these mountings I used M8 bolts to make sure all the downforce would go through to the chassis without being lost in any flexing.
Next step is to bond the alloy strip with resin and matting to spread the load and stop the nose cone cracking where it is mounted.
