Since no aftermarket spoile can for fill my need
So I decide to build one by myself
And with swan neck it generates much more down force compare to traditional mountings
Because it smooth out the turbulence at low pressure zone
Here are own inhouse design bolt on swanneck wing no welding reguire , keep ur trunk space for track wheel and tool !!!
On my RX7
Hows every one think ?😀
As for me I think it look freaking cool!!!
Still trying setup the suspension with this spoiler

PS: the reason I mount higher then normal is I have 100L fuel cell , with 3 fuel pump , surge tank , dry brake tube , so inorder not to knock out my fuel man , I have to mount wing higher and that also rule out to mount the wing at trunk

And the wing stay is maching from 10mm of 6061 and the base plate (the part u bolt on to trunk) is 6mm of high Carbon steel so is rock solids even over 150mile

 

Looks like some crazy *** no rule time attack stuff!

You could add a few more elements for more downforce or go with the zero drag downforce device below





Ha ha ha.

Anyways, if it brings your times down, bring it on. Who cares how it looks.

 

U can always use at track day
To get fast is more important then it look
