More on how to make it fit. The good news is that it requires no modification to the car. The holes are already there to utilize for the front brackets! I used the existing holes in the rear crossmember and added 1/4-20 nutserts. From there I fabbed some simple brackets:
Installing nutserts-these things are the best thing ever!

Then fabbed up simple brackets using 1/16 aluminum flat stock which I riveted to the diffuser.

Not until next week unfortunately. The car is on the lift at home and the seats are out-so it can’t move (don’t want to trip an airbag light). Once the seats are back next week (doing some cool stuff) I will reinstall and get the car on the ground.

All in all, install was not too bad and the diffuser is held in place with 4 allen head bolts. Even with just 4 bolts-this thing isn't going anywhere-I almost hung off the back of it with my full weight (215 lbs) to try to adjust one of the brackets by force and it did nothing. Overall, very pleased with the outcome and I will post some pics of the car next week when its back on the ground.

What is the ground clearance? Looks like you can bottom out easily.

Ground clearance is low for the fins-I would say 3-4 inches max. Keep in mind, my car is on the lowest spring perch setting in the rear with h&r springs. It’s lower than most gt3s...so I am probably an extreme example. Thankfully I have lots of experience with very low cars but even still I am sure it will get some road rash (the fins)

Looks really good. Waiting on pics of it on the ground. I had a shop install my H&R springs. What is your rear wheel gap? Trying to see what level they left the rear perches at. Also did you check to see if there is aftermarket units of this, I hate cutting up perfectly fitting OEM stuff ><
