i didn't really get why Cwiz wanted this particular wing till i saw it on his car at zdayz this year. it looks great and it fits the car really well.
i saw y'all mentioning adjusting the wing earlier. i don't know a whole lot about wings but i can tell you from what we've learned on the world challenge car i shoot for, on wings like this you are better off to leave it at zero * angle of attack. if you can find info on the downforce provided, it will probably be in japanese, that can help take the guess work out of it. even for HPDE/track days, you are better off leaving it at 0* AOA until you truly feel you need more rear downforce. the APR wing, which is a similar wing, will stall once you get more than a few degrees higher than 0. at that point you are just producing drag and not much downforce. however, i will say that on the race car, changing from the stock nismo wing to the aeromotions wing made a vast improvement in rear grip, especially under braking. it helped a lot with the "ice mode" problems. when driving on the limit, the rear brakes on these cars lock up before the fronts and the ABS freaks out. adding downforce to the rear helped counter this. now we have a standalone ABS unit so we don't worry about such things
