The mounting bracket to the trunk for the replica is a one piece design that the wing arms are bolted too while the authentic is a two piece design that sandwiches the arm. Although in the picture you have linked it is a sandwiched design so maybe they have changed over.

Besides that I think it is almost spot on. Easiest thing to install on the car was this wing.

Definitely no wobble at sub 100 speeds, it's on there solid.

Havent gone 100+ so can't speak +100. I've only put probably 40 miles on the car since the kit was installed a year ago -.-.

I have a few pics I could dig up for you
