If we're all worried about downforce loading, then it should have stanchions from the wing through to the frame.

The design of the gurney creates the maximum amount of down force. The metal has the advantage that it will weep and give warning signs whereas the CF will most likely crack and fail either once or for a short number of loads. The rear wing is fabricated from ultra-lightweight high quality dry carbon fiber. BOTH are going to deflect and squish the trunk seal as it loads, and from there it's a matter of whether the dogbone footrprint will overwhelm and fail on CF before it would materially fail on thin gauge metal. 2015 Subaru WRX STI The production version WRX STI will be displayed next week at the 2014 Detroit Auto Show, just a few months after the WRX was unveiled in L.A.

Subaru says that wing isn't just for showit adds downforce. It's there to give the intercooler some air. In summary, I'm not certain the track wing and associated loads at speed are any better suited by flimsy metal in the OEM lid either. The hood scoop on the 2015 Subaru WRX STI isn't just for looks. If the mounting points were inboard where the lid bridges the three sides, I'd be much more concerned.īesides, let's be honest, if we're really worried about 500 lbs of distributed load (one for each leg so 250 lbs of load on each side) then there'd be some sort of direct structure through to the chassis.

Given the outboard location of the dogbones directly over the lid seams and supporting body seal/shelf underneath it, I find it difficult to believe that the OEM metal deck lid would fair any better than the CF one.
