Default New front wing stays, old ones broke again

The front wing stays rusted and broke again, did a temporary fix a few months ago, but finally itís time to make some new ones which will hopefully be more resilient to the elements.

Started with two 1 meter 10mm diameter solid rods


A piece of bar to turn into the bracket that will hold the rod on to the front uprights with a U clamp (51mm u clamp)



Bracket cut shown with U clamp.



Test fitted to the uprights



Used a clamp to hold the round bar to the bracket to get a it roughly lined up.



Used a caliper to evenly space the round bar away from the alloy wheels



Held in by hand for a better view of the bracket and round bar



Tack welded the round bar to the bracket



My temporary workshop setup Ė donít recommend using a workmate for welding due to the risk of burning wood and fire. Use a metal welding table, which I donít have in my garage. Grabbed the round bar quite far away from the weld so it was fine. Also used a TIG so no splatter.



Iím still a total amature at welding but these are OK



The main thing is that is holds together well. The angle grinder hides the bad.



One of the most time consuming parts of the build was creating a jig so that all four final bends ended up very similar.



It may only look like two bends, but there are hours of measuing, eyeing up and carefully deciding where the bends need to go.



The rod lines up with the holes on the carbon wings.



Now hereís one of those things that happens all too often on a project Ė the rods ended up 10mm too high on the first go. This is jig MK2 with the height adjusted. It did mean having to straighten out the rod and rebend it to the right position.



Hereís a test fit of the front of the rod bent into place



The jig is holding the back up.



Left to right the mount positions are little way off on the back, so some creative bending and P clip positioning evens out the rod placement.



The back bent into shape, again two bends took many hours to get to the right position.



Here are the P clips that will mount the wings to the rod



First test fit of the driver side, got some really nice new A4 grade cup washers, bolts and nuts from Westfield Fastners to finish it off.





Test fit on the passenger side. The wing was too close to the tyre so this one needed a bit more fine tuning to get it right.



A view from underneath with the wheel off.



There is enough gap between the tyre and the carbon, looks quite close from this angle. If there are problems it is easy to tweak the bends to create more clearance.



Before and after, the before is version 3 of the mounts which also failed eventually.



Ahh shiny parts!
